Viewer discretion
is advised.
3
00:00:12,033 --> 00:00:14,066
FISHBURNE: It is, perhaps,
the most famous expedition
4
00:00:14,200 --> 00:00:16,033
of the twentieth century.
5
00:00:17,500 --> 00:00:20,367
Ernest Shackleton's
disastrous mission
6
00:00:20,500 --> 00:00:22,100
to cross Antarctica.
7
00:00:23,734 --> 00:00:26,700
When Shackleton's ship,
The Endurance,
8
00:00:26,834 --> 00:00:28,166
got snared in polar ice...
9
00:00:29,133 --> 00:00:32,333
The mission became an all out
fight for survival.
10
00:00:34,400 --> 00:00:37,567
The ship disappeared
beneath the surface.
11
00:00:39,033 --> 00:00:42,900
Tonight's mystery: What happened
to Shackleton's ship?
12
00:00:44,200 --> 00:00:45,467
Can we find it?
13
00:00:46,433 --> 00:00:48,200
And what secrets might it hold?
14
00:00:50,367 --> 00:00:53,133
Now, for the first time
an expedition
15
00:00:53,266 --> 00:00:55,867
is heading into the frozen
waters of the Antarctic.
16
00:00:57,000 --> 00:00:58,433
Put it in the water!
17
00:00:59,000 --> 00:01:00,734
This is pretty much
the Holy Grail
18
00:01:00,867 --> 00:01:02,433
because it's so inaccessible.
19
00:01:03,066 --> 00:01:05,200
FISHBURNE: Armed with
the latest technology...
20
00:01:05,333 --> 00:01:06,633
Ready for armed state.
21
00:01:10,400 --> 00:01:12,800
FISHBURNE: And
a century old logbook...
22
00:01:15,100 --> 00:01:17,734
They'll use sonar
and drone submarines
23
00:01:17,867 --> 00:01:19,967
to track down
Shackleton's famous ship.
24
00:01:21,367 --> 00:01:23,133
But with winter approaching...
25
00:01:24,467 --> 00:01:26,333
There is no margin for error.
26
00:01:26,934 --> 00:01:28,900
MAN: Oh, well... What the hell
is going on?
27
00:01:29,033 --> 00:01:30,800
This is the start of it here.
28
00:01:30,934 --> 00:01:33,367
FISHBURNE: The hunt
for The Endurance.
29
00:01:33,500 --> 00:01:33,600
Tonight on
History's Greatest Mysteries.
30
00:01:55,433 --> 00:01:56,533
FISHBURNE: Antarctica,
31
00:01:59,667 --> 00:02:01,633
the most extreme place on Earth.
32
00:02:04,367 --> 00:02:06,333
Temperatures reach 100 below.
33
00:02:09,266 --> 00:02:12,000
Wind whips across it
at 200 mph.
34
00:02:16,767 --> 00:02:19,633
This frozen continent
surrounds the South Pole.
35
00:02:21,533 --> 00:02:25,533
It's a vast land,
entirely covered in ice.
36
00:02:28,300 --> 00:02:30,033
Somewhere in these frozen seas
37
00:02:30,166 --> 00:02:32,300
lies the Holy Grail
of shipwrecks,
38
00:02:33,600 --> 00:02:34,734
the Endurance,
39
00:02:35,867 --> 00:02:38,133
the ship that carried
legendary explorer,
40
00:02:38,266 --> 00:02:41,834
Sir Ernest Shackleton,
south in 1914.
41
00:02:43,667 --> 00:02:46,100
(MAN SPEAKING
INDISTINCTLY ON RADIO)
42
00:02:46,433 --> 00:02:49,100
Down here,
the water is so cold,
43
00:02:49,233 --> 00:02:51,767
the wooden ship is likely
perfectly preserved.
44
00:02:55,667 --> 00:02:57,400
But it's so hard to get to
45
00:02:57,533 --> 00:02:59,200
that no one's ever been able to
46
00:02:59,333 --> 00:03:01,533
hunt for the wreck.
Until now.
47
00:03:06,400 --> 00:03:08,166
Flying in from across the globe
48
00:03:08,300 --> 00:03:10,800
is an international team
of ship hunters,
49
00:03:10,934 --> 00:03:12,900
explorers, and scientists.
50
00:03:16,166 --> 00:03:18,400
Two years in the planning
51
00:03:18,533 --> 00:03:23,300
and over $250 million of
cutting-edge technology
52
00:03:23,433 --> 00:03:27,500
make them think
they can pull off a world first.
53
00:03:27,633 --> 00:03:31,333
If the data that we have for
the wreck site is correct,
54
00:03:31,467 --> 00:03:32,834
then we'll find it.
55
00:03:36,500 --> 00:03:38,100
Maritime
archaeologist Mensun Bound
56
00:03:38,233 --> 00:03:39,900
is heading up the search.
57
00:03:41,834 --> 00:03:44,300
He's got 40 years' experience
excavating shipwrecks,
58
00:03:46,633 --> 00:03:49,467
but finding the Endurance
is the ultimate challenge.
59
00:03:50,767 --> 00:03:52,233
BOUND: The Endurance is,
to my mind,
60
00:03:52,367 --> 00:03:54,633
the most famous wreck
of all time.
61
00:03:54,767 --> 00:03:58,834
You know, she's up there
with the Titanic.
62
00:03:58,967 --> 00:04:00,233
If anybody can find
the Endurance,
63
00:04:00,367 --> 00:04:02,734
it's going to be
this expedition.
64
00:04:06,433 --> 00:04:10,233
This is the greatest wreck hunt
that there's ever been.
65
00:04:13,367 --> 00:04:14,967
FISHBURNE: The first mission
for the team members
66
00:04:15,100 --> 00:04:16,834
not arriving by chopper...
67
00:04:17,300 --> 00:04:21,533
...is just getting onto
the ship with their gear.
68
00:04:24,000 --> 00:04:25,433
Three meters, closing.
69
00:04:25,567 --> 00:04:28,500
FISHBURNE:
Access from a 100-ft ice cliff
70
00:04:28,633 --> 00:04:30,233
is not for the faint of heart.
71
00:04:32,767 --> 00:04:34,467
-Okay, everyone happy?
-Yep.
72
00:04:34,600 --> 00:04:36,400
Good to go.
73
00:04:36,533 --> 00:04:39,367
You'll be in the centre like
this, holding here and here,
74
00:04:39,500 --> 00:04:40,667
-basically
-Okay.
75
00:04:40,800 --> 00:04:42,233
And then the other guys
will surround you.
76
00:04:43,266 --> 00:04:44,767
It's quite interesting.
77
00:04:50,700 --> 00:04:53,834
This expedition will face
the same risks and dangers
78
00:04:53,967 --> 00:04:56,266
that Shackleton did
a century ago.
79
00:04:57,834 --> 00:04:59,800
But today's team
has come prepared.
80
00:05:01,734 --> 00:05:02,667
The ROV has the tension.
81
00:05:02,800 --> 00:05:04,633
-You can release it.
-Got it.
82
00:05:04,767 --> 00:05:06,367
It's just going to go under.
83
00:05:07,600 --> 00:05:09,233
Steve Saint Amour,
84
00:05:09,367 --> 00:05:11,633
leads one of the elite teams
of sub-sea explorers.
85
00:05:12,867 --> 00:05:14,467
SAINT AMOUR:
Our job will be to document
86
00:05:14,600 --> 00:05:17,333
the condition of the wreck
on the sea floor.
87
00:05:17,467 --> 00:05:19,700
FISHBURNE: Based in Maryland,
his team has found
88
00:05:19,834 --> 00:05:24,200
missing plane wrecks and most
famously, surveyed the Titanic.
89
00:05:29,166 --> 00:05:31,166
But hunting Shackleton's wreck
90
00:05:31,300 --> 00:05:33,033
is their most challenging
mission yet.
91
00:05:38,567 --> 00:05:41,533
A ship has not been to the
Shackleton location primarily
92
00:05:41,667 --> 00:05:46,000
due to the ice pack and how
difficult it is to get here.
93
00:05:47,300 --> 00:05:49,500
This is the equivalent
of going to Mars
94
00:05:49,633 --> 00:05:53,567
and looking for, you know,
the wreckage of a space craft.
95
00:05:53,700 --> 00:05:55,367
It's just that remote.
96
00:05:58,266 --> 00:06:00,633
To help him search,
Steve's got a secret weapon.
97
00:06:03,300 --> 00:06:06,233
A purpose-built,
remotely operated vehicle,
98
00:06:06,367 --> 00:06:08,166
or ROV.
99
00:06:12,500 --> 00:06:15,734
This $2 million bot weighs in
at over 6,000 pounds.
100
00:06:18,066 --> 00:06:20,166
It's equipped with
deep sea cameras
101
00:06:20,300 --> 00:06:23,066
and two articulated
titanium arms.
102
00:06:26,266 --> 00:06:31,300
Its mission: to dive to the
sea bed and explore the wreck.
103
00:06:32,500 --> 00:06:35,667
It can descend to nearly
four miles under the water
104
00:06:35,800 --> 00:06:37,333
and withstand pressure
105
00:06:37,467 --> 00:06:39,633
that would crush a human
in an instant.
106
00:06:42,133 --> 00:06:44,266
Before the ship sets off,
107
00:06:44,400 --> 00:06:47,300
Steve's team needs to give
their robot a health check.
108
00:06:49,767 --> 00:06:52,533
And so one of the things we do
to prepare for the mission
109
00:06:52,667 --> 00:06:54,533
is go through and double-check
all the connections,
110
00:06:54,667 --> 00:06:57,233
and tighten up hardware.
111
00:06:57,367 --> 00:06:59,834
FISHBURNE: Dave O'Hara,
from Northern Ireland
112
00:06:59,967 --> 00:07:03,100
-is Steve's pilot.
-[Dave] Through there.
113
00:07:04,433 --> 00:07:05,967
In there.
114
00:07:06,100 --> 00:07:08,433
An ex-British
navy engineer,
115
00:07:08,567 --> 00:07:11,467
he's been working on robot subs
for 12 years.
116
00:07:12,333 --> 00:07:14,133
O'HARA: We've had the brains
of the system out,
117
00:07:14,266 --> 00:07:16,400
put it back in
and we'll hook her back up
118
00:07:16,533 --> 00:07:18,400
and give it a test
again in a few minutes.
119
00:07:21,433 --> 00:07:24,133
For me personally,
it's a bucket list job.
120
00:07:24,266 --> 00:07:26,533
The shipwreck side of things
have got me inspired
121
00:07:26,667 --> 00:07:30,734
to come do this for a living,
watching guys find Titanic.
122
00:07:32,400 --> 00:07:34,100
Just for the
history behind it, the story,
123
00:07:34,233 --> 00:07:35,900
the human aspect of it.
124
00:07:36,800 --> 00:07:38,500
And I think that's the same
with Endurance.
125
00:07:38,633 --> 00:07:40,900
Okay, guys, just let her be.
I'm gonna start the hydraulics.
126
00:07:42,767 --> 00:07:45,633
FISHBURNE: Dave's confident
he can get the sub 10,000 feet
127
00:07:45,767 --> 00:07:48,200
down to the wreck.
128
00:07:48,333 --> 00:07:49,600
But first they've got
to find it.
129
00:07:53,166 --> 00:07:55,967
Fortunately, the team has a big
clue to where it could be.
130
00:07:59,633 --> 00:08:02,033
To find the exact spot
to search,
131
00:08:02,166 --> 00:08:03,467
wreck archaeologist
Mensun Bound
132
00:08:03,600 --> 00:08:05,633
is investigating nautical charts
133
00:08:05,767 --> 00:08:08,066
and the ship's original log
134
00:08:08,200 --> 00:08:10,533
kept meticulously
by Shackleton's captain,
135
00:08:10,667 --> 00:08:11,834
Frank Worsley.
136
00:08:14,133 --> 00:08:17,400
These record Endurance's
position on the day she sank.
137
00:08:19,667 --> 00:08:22,166
It gives us the coordinates,
a latitude and a longitude.
138
00:08:23,500 --> 00:08:25,033
If we look at the chart,
139
00:08:25,166 --> 00:08:27,834
here we have it, right here.
140
00:08:29,767 --> 00:08:31,467
This is where she sank.
141
00:08:31,600 --> 00:08:33,600
This is "X marks the spot."
142
00:08:35,734 --> 00:08:37,233
FISHBURNE: Using the data,
143
00:08:37,367 --> 00:08:40,967
Mensun calculates a target
1,200 miles away
144
00:08:41,100 --> 00:08:42,934
across the treacherous
Weddell Sea.
145
00:08:43,734 --> 00:08:45,000
It's a minefield
146
00:08:46,533 --> 00:08:49,400
of giant waves and jagged ice.
147
00:08:53,266 --> 00:08:57,133
LARSON: The Weddell Sea is
a churning bed of sea ice.
148
00:08:57,266 --> 00:09:01,467
This sea ice breaks into pieces
and it floats around
149
00:09:01,600 --> 00:09:05,333
and runs into each other,
throwing up pressure ridges,
150
00:09:05,467 --> 00:09:08,467
and you never know when it will
turn totally solid again.
151
00:09:11,667 --> 00:09:14,133
FISHBURNE: The expedition is
also in a race against time.
152
00:09:16,166 --> 00:09:18,700
The Weddell Sea is
full of ice year round,
153
00:09:19,667 --> 00:09:21,300
but as winter approaches,
154
00:09:21,433 --> 00:09:23,900
the ocean around the continent
freezes over.
155
00:09:25,834 --> 00:09:29,200
Impassable sea ice
covering an area
156
00:09:29,333 --> 00:09:32,433
one-and-a-half times the
size of the United States.
157
00:09:39,667 --> 00:09:43,300
The team has a short window
to get in and back out
158
00:09:43,433 --> 00:09:46,100
or they'll get stuck
in the ice.
159
00:09:46,233 --> 00:09:48,834
Anyone going
into that area with a ship
160
00:09:48,967 --> 00:09:52,166
is putting their ship
and their crew in jeopardy.
161
00:10:01,233 --> 00:10:03,467
FISHBURNE:
In 1914, two years after
162
00:10:03,600 --> 00:10:05,000
the sinking
of the Titanic,
163
00:10:05,133 --> 00:10:09,200
British explorer, Sir Ernest
Shackleton, heads south.
164
00:10:11,500 --> 00:10:13,166
ERNEST SHACKLETON:
I believe it is in our nature
165
00:10:13,300 --> 00:10:17,200
to explore,
reach out into the unknown.
166
00:10:17,333 --> 00:10:20,867
The only true failure
would be not to explore at all.
167
00:10:23,700 --> 00:10:26,533
FISHBURNE: It's the golden
age of polar exploration.
168
00:10:27,767 --> 00:10:30,233
Shackleton is full of ambition,
169
00:10:30,367 --> 00:10:33,166
seeking glory for himself
and his country.
170
00:10:35,233 --> 00:10:37,934
He was really driven
by the fact that
171
00:10:38,066 --> 00:10:39,900
it was one of the last few
places on Earth
172
00:10:40,033 --> 00:10:41,734
that hadn't
been touched by man
173
00:10:41,867 --> 00:10:44,367
and he wanted to be one
of the first persons there.
174
00:10:48,533 --> 00:10:52,967
Antarctica was the last place
to show this sense of adventure.
175
00:10:53,100 --> 00:10:54,700
It was the last challenge left.
176
00:11:00,333 --> 00:11:02,700
FISHBURNE: Shackleton's aim,
to make history
177
00:11:02,834 --> 00:11:06,233
by crossing the entire
Antarctic continent
178
00:11:06,367 --> 00:11:09,767
from coast to coast
for the first time.
179
00:11:09,900 --> 00:11:12,000
A hundred years ago, crossing
Antarctica would be more
180
00:11:12,133 --> 00:11:15,000
difficult than us
going to the moon today.
181
00:11:18,333 --> 00:11:20,333
I think it's the nature of man
182
00:11:20,467 --> 00:11:24,066
to always see something
we haven't seen before,
183
00:11:24,200 --> 00:11:25,867
whether it's the moon
or the South Pole.
184
00:11:30,166 --> 00:11:32,734
ANKER: Shackleton
and his 27 men,
185
00:11:32,867 --> 00:11:36,600
they sailed off
what we knew of the world.
186
00:11:39,767 --> 00:11:42,266
FISHBURNE: But Shackleton
will never even make landfall.
187
00:11:43,700 --> 00:11:46,600
Here at the end of the Earth,
188
00:11:46,734 --> 00:11:50,133
Shackleton's ship,
the Endurance, will sink
189
00:11:52,633 --> 00:11:55,133
in a disaster that will
capture the world's attention.
190
00:12:01,567 --> 00:12:05,200
Fully loaded, the Agulhas II
finally sets off,
191
00:12:05,333 --> 00:12:07,500
ready to take on
the Weddell Sea.
192
00:12:09,600 --> 00:12:11,433
So much has gone
into this project,
193
00:12:11,567 --> 00:12:13,867
so many years of work,
so many dreams.
194
00:12:14,000 --> 00:12:19,633
It feels like my whole life
has come down to this moment.
195
00:12:22,000 --> 00:12:25,000
FISHBURNE: Now it's time
to put everything to the test.
196
00:12:26,900 --> 00:12:28,800
The team will battle ice...
197
00:12:28,934 --> 00:12:31,500
SAINT AMOUR: Roger,
I got a berg right on the stern.
198
00:12:31,633 --> 00:12:33,734
-Hurry, please.
-...bitter cold...
199
00:12:33,867 --> 00:12:37,533
-We are now stuck.
-...and extreme depth.
200
00:12:37,667 --> 00:12:39,567
Guys, we're gonna
bring it back.
201
00:12:39,700 --> 00:12:43,667
With so much at stake, how will
they overcome the challenges?
202
00:12:43,800 --> 00:12:45,667
Pod's gone. I don't know
what to say, really.
203
00:13:04,900 --> 00:13:06,333
FISHBURNE:
After five days at sea,
204
00:13:07,400 --> 00:13:09,166
the expedition to find the ship
205
00:13:09,300 --> 00:13:10,934
of legendary explorer,
Sir Ernest Shackleton
206
00:13:12,567 --> 00:13:13,867
is making good progress.
207
00:13:18,600 --> 00:13:20,934
Now 1,500 miles
from her starting point
208
00:13:21,066 --> 00:13:22,100
at Penguin Bukta,
209
00:13:23,333 --> 00:13:25,633
the crew is zeroing in
on the wreck site.
210
00:13:31,000 --> 00:13:34,367
On deck, Louisiana native
and former Air Force engineer,
211
00:13:34,500 --> 00:13:38,133
Devon James, is part of
a second elite team
212
00:13:38,266 --> 00:13:39,934
hunting the 100-year-old wreck.
213
00:13:42,967 --> 00:13:46,500
It's his job to look after
a critical set of equipment,
214
00:13:46,633 --> 00:13:52,100
two autonomous
underwater vehicles, or AUVs.
215
00:13:52,233 --> 00:13:54,500
JAMES: It's basically a drone,
just like an aerial drone,
216
00:13:54,633 --> 00:13:56,333
but we use it in the ocean.
217
00:13:56,467 --> 00:13:58,867
So this is used
all over the world
218
00:13:59,000 --> 00:14:02,433
to survey the sea
floor without an operator
219
00:14:02,567 --> 00:14:04,166
going below the surface.
220
00:14:04,300 --> 00:14:06,100
Coming to you.
221
00:14:06,233 --> 00:14:08,800
FISHBURNE: Also working
on the subs is Chad Bonin.
222
00:14:08,934 --> 00:14:10,734
Like Devon, he's ex-military.
223
00:14:10,867 --> 00:14:12,734
-Forward.
-Roger.
224
00:14:12,867 --> 00:14:15,400
We haven't dealt with ice
conditions like this before.
225
00:14:16,967 --> 00:14:19,867
We were hand picked
to come onto this job,
226
00:14:20,000 --> 00:14:22,533
so there's a lot of pressure
to complete the task.
227
00:14:23,667 --> 00:14:25,800
FISHBURNE: Despite
the challenges of sending
228
00:14:25,934 --> 00:14:29,767
their AUV subs under the ice,
Chad's got a good attitude.
229
00:14:29,900 --> 00:14:31,700
As long as we're
layered up we're okay.
230
00:14:31,834 --> 00:14:33,734
We're from South Louisiana,
it's usually hot weather.
231
00:14:41,767 --> 00:14:43,867
FISHBURNE: The team
knows where to head,
232
00:14:44,000 --> 00:14:46,567
but getting
there is tough.
233
00:14:49,600 --> 00:14:52,567
The expedition's hopes
rest on the Agulhas II.
234
00:14:56,367 --> 00:14:58,166
Weighing in at 14,000 tons
235
00:14:59,667 --> 00:15:01,700
and costing $170 million,
236
00:15:04,367 --> 00:15:07,767
this ship is designed to smash
through ice three feet thick.
237
00:15:16,767 --> 00:15:19,467
A double hull
of extra thick steel protects
238
00:15:19,600 --> 00:15:25,166
the Agulhas II,
and in the engine room,
239
00:15:25,300 --> 00:15:28,000
second engineer,
Mark O'Reilly
240
00:15:28,133 --> 00:15:30,266
is pushing her four engines
to the limit.
241
00:15:31,633 --> 00:15:34,600
These deliver 12,000 horsepower.
242
00:15:36,066 --> 00:15:37,500
O'REILLY: This is one
of two prop shafts.
243
00:15:37,633 --> 00:15:40,100
six thousand horsepower
available on each
244
00:15:40,233 --> 00:15:43,800
and that will give us
enough power to break through
245
00:15:43,934 --> 00:15:45,533
one meter of ice
at seven miles per hour.
246
00:15:58,233 --> 00:16:00,133
FISHBURNE:
The Agulhas II is built
247
00:16:00,266 --> 00:16:02,467
for the worst
conditions on the planet,
248
00:16:02,600 --> 00:16:04,400
but even for this beast,
249
00:16:04,533 --> 00:16:06,700
hitting ice at speed
is bad news.
250
00:16:08,934 --> 00:16:11,800
Captain Freddie Ligthelm,
is the ice pilot.
251
00:16:11,934 --> 00:16:14,133
Part of the South African crew,
252
00:16:14,266 --> 00:16:17,867
he has 15 years' experience
in the Weddell Sea.
253
00:16:18,000 --> 00:16:21,266
If we should hit any sea ice
here at 15 knots,
254
00:16:21,400 --> 00:16:24,967
it could possibly cause heavy
damage to the vessel.
255
00:16:25,100 --> 00:16:28,033
So we are continuously
looking out.
256
00:16:28,166 --> 00:16:30,367
FISHBURNE: The Titanic
famously sank in 1912
257
00:16:31,600 --> 00:16:34,934
because it hit an iceberg
at speed.
258
00:16:35,066 --> 00:16:37,734
One wrong move could bring
this ship to the same fate.
259
00:16:39,633 --> 00:16:43,000
But unlike the Titanic,
the Agulhas II
260
00:16:43,133 --> 00:16:46,000
has an arsenal of
modern navigational tools.
261
00:16:47,934 --> 00:16:50,333
LIGTHELM: This is us here
and this is our speed vector
262
00:16:50,467 --> 00:16:52,266
and you can see
that this iceberg
263
00:16:52,400 --> 00:16:54,500
is at a distance of 8.8 miles.
264
00:16:56,934 --> 00:17:00,233
Sometimes you could get
100 targets on the radar
265
00:17:00,367 --> 00:17:02,100
at a 12-mile range,
266
00:17:02,233 --> 00:17:04,667
and you would try to then just
skirt as much as you can.
267
00:17:06,700 --> 00:17:09,333
FISHBURNE: To reach
the wreck site, the Agulhas II
268
00:17:09,467 --> 00:17:12,500
has been sailing around the
northern edge of the ice pack.
269
00:17:12,633 --> 00:17:15,467
She will only head into
the thicker ice when she has to.
270
00:17:18,900 --> 00:17:22,133
This sea ice is what explorer
Sir Ernest Shackleton faced
271
00:17:22,266 --> 00:17:23,967
more than 100 years ago.
272
00:17:28,000 --> 00:17:31,433
LARSON: When Shackleton took
his ship into the Weddell Sea,
273
00:17:31,567 --> 00:17:34,800
he knew the tremendous risk
he'd never make it out alive.
274
00:17:38,500 --> 00:17:40,500
FISHBURNE: Caught on camera
by photographer Frank Hurley,
275
00:17:42,233 --> 00:17:45,233
the Endurance picks her way
through hundreds of miles
276
00:17:45,367 --> 00:17:47,033
of pack ice.
277
00:17:48,166 --> 00:17:51,400
But how could the 144-foot
wooden ship
278
00:17:51,533 --> 00:17:55,567
avoid the fate of the Titanic
just two years previously?
279
00:18:00,100 --> 00:18:02,133
Wreck archaeologist,
Mensun Bound,
280
00:18:02,266 --> 00:18:04,800
is studying the ship's plans.
281
00:18:04,934 --> 00:18:08,000
This is the original design
for the Endurance.
282
00:18:08,133 --> 00:18:11,400
She really was
a beautiful, beautiful vessel.
283
00:18:11,533 --> 00:18:13,967
If you look at her bow,
you can see it's got
284
00:18:14,100 --> 00:18:16,800
four huge oaken
timbers here.
285
00:18:16,934 --> 00:18:19,467
That's two times more than any
other ship that I know of.
286
00:18:21,133 --> 00:18:22,567
FISHBURNE: Her bow
is over four foot thick.
287
00:18:24,433 --> 00:18:27,567
The keel or spine of the ship
is seven foot of solid oak.
288
00:18:29,967 --> 00:18:32,467
And to stop her being
ripped apart by ice,
289
00:18:32,600 --> 00:18:35,266
her hull is cloaked in a wood
called "greenheart",
290
00:18:37,066 --> 00:18:40,633
so durable and strong
that it's heavier than iron.
291
00:18:42,500 --> 00:18:46,066
It is extraordinarily hard.
292
00:18:46,200 --> 00:18:49,800
It's so hard, you can't
even drive a nail into it.
293
00:18:49,934 --> 00:18:52,333
But this is what
Shackleton needed
294
00:18:52,467 --> 00:18:56,433
because it is resistant
to the kind of wear and tear
295
00:18:56,567 --> 00:18:59,200
and abrasion that this hull was
going to have to withstand
296
00:18:59,333 --> 00:19:01,233
once it got into the Antarctic.
297
00:19:01,367 --> 00:19:04,166
FISHBURNE: Shackleton named
his ship Endurance
298
00:19:04,300 --> 00:19:07,100
after his family motto,
299
00:19:07,233 --> 00:19:08,700
"By endurance we conquer."
300
00:19:10,300 --> 00:19:12,967
And the Endurance
will need all her strength
301
00:19:13,100 --> 00:19:14,600
as she sails
further into the ice.
302
00:19:20,467 --> 00:19:22,266
While the ice makes
getting to the wreck site
303
00:19:22,400 --> 00:19:24,834
a massive challenge...
304
00:19:24,967 --> 00:19:27,700
these frigid waters
are also the reason
305
00:19:27,834 --> 00:19:30,367
Shackleton's wooden ship
is likely preserved
306
00:19:30,500 --> 00:19:32,233
at the bottom of the sea.
307
00:19:32,367 --> 00:19:36,533
In warmer seas, marine
creatures eat wooden ships,
308
00:19:36,667 --> 00:19:41,100
the most destructive,
a mollusk called "shipworm".
309
00:19:41,233 --> 00:19:45,367
Shipworm can be incredibly
destructive to wooden ships.
310
00:19:47,367 --> 00:19:49,100
And they are voracious.
311
00:19:49,233 --> 00:19:52,000
They just eat anything and
everything in no time at all.
312
00:19:52,133 --> 00:19:55,367
They can be up two feet long
and they just eat, eat, eat.
313
00:20:01,233 --> 00:20:04,066
FISHBURNE: Recent experiments
have revealed that shipworms
314
00:20:04,200 --> 00:20:06,734
can't survive in the freezing
Antarctic waters.
315
00:20:09,266 --> 00:20:11,767
Newly-discovered wrecks
from Northern Canada
316
00:20:11,900 --> 00:20:14,800
prove that icy seas can
preserve wooden ships
317
00:20:14,934 --> 00:20:16,567
even older than the Endurance.
318
00:20:21,033 --> 00:20:22,967
But even if
it's well preserved,
319
00:20:23,100 --> 00:20:26,100
the Endurance
rests 10,000 feet down.
320
00:20:26,233 --> 00:20:30,400
And right now, the sea there
is entirely frozen over.
321
00:20:32,900 --> 00:20:34,934
Getting the subs under the ice
322
00:20:35,066 --> 00:20:37,767
will push the team
to the limit.
323
00:20:37,900 --> 00:20:39,333
BONIN: It's armed
and ready to go.
324
00:20:42,000 --> 00:20:43,934
JAMES: AUV in the water.
325
00:20:44,066 --> 00:20:45,500
Kill the lights and see
what we've got.
326
00:20:46,500 --> 00:20:48,033
Whoa.
327
00:20:49,166 --> 00:20:50,700
We lost it.
328
00:21:10,066 --> 00:21:13,033
FISHBURNE:
For 11 days, the expedition
329
00:21:13,166 --> 00:21:15,266
to find
Shackleton's lost wreck
330
00:21:15,400 --> 00:21:17,934
in the frozen waters
of Antarctica
331
00:21:18,066 --> 00:21:22,066
has risked raging
storms and ice fields.
332
00:21:31,433 --> 00:21:35,000
Now the crew is beyond
the reach of helicopter rescue.
333
00:21:35,133 --> 00:21:37,533
If something goes wrong,
they're on their own.
334
00:21:41,100 --> 00:21:44,300
They've reached the west side
of the Weddell Sea,
335
00:21:44,433 --> 00:21:48,834
as close as they can get to
the wreck site in open water.
336
00:21:48,967 --> 00:21:52,667
Beyond their position
is pack ice up to 16 feet thick.
337
00:22:01,967 --> 00:22:05,433
Before they break in,
Louisiana boys Chad and Devon
338
00:22:05,567 --> 00:22:09,934
want to test their AUV
subs under a nearby ice floe.
339
00:22:10,066 --> 00:22:12,400
We're going into sea trials
where we're actually going
340
00:22:12,533 --> 00:22:15,867
to launch the AUV and
we'll go ahead and release it,
341
00:22:16,000 --> 00:22:18,233
send it underwater.
342
00:22:18,367 --> 00:22:21,533
FISHBURNE: At the wreck site,
the AUVs will dive down
343
00:22:21,667 --> 00:22:24,600
and use sonar to scan
the sea bed for the wreck.
344
00:22:26,233 --> 00:22:27,767
It may sound simple,
345
00:22:27,900 --> 00:22:32,400
but even testing the AUVs
like this is risky.
346
00:22:32,533 --> 00:22:34,367
They've never been
under Antarctic ice.
347
00:22:36,066 --> 00:22:39,100
AUV team leader Channing Thomas
knows the dangers.
348
00:22:41,000 --> 00:22:42,433
THOMAS: There is
a lot of pressure.
349
00:22:44,200 --> 00:22:46,500
If this works,
it's going to be extraordinary.
350
00:22:49,300 --> 00:22:52,734
Two years of planning
and tens of millions of dollars
351
00:22:52,867 --> 00:22:55,900
rests, on the AUV sub
doing its job right.
352
00:22:56,500 --> 00:22:58,500
JAMES:
We're being extra cautious
353
00:22:58,633 --> 00:22:59,934
before we put it in the water.
354
00:23:00,133 --> 00:23:02,934
Once we launch it,
there's no turning back.
355
00:23:06,767 --> 00:23:08,567
BONIN: Alright, let's go get us
a successful launch.
356
00:23:10,000 --> 00:23:11,867
FISHBURNE: Chad is taking
no chances.
357
00:23:12,000 --> 00:23:13,433
Ice is a constant threat.
358
00:23:17,166 --> 00:23:19,834
The fast response craft,
or FRC,
359
00:23:19,967 --> 00:23:21,834
is the only way he can hope
to protect
360
00:23:21,967 --> 00:23:25,000
their multi-million dollar sub
at the surface.
361
00:23:25,133 --> 00:23:29,467
We're on standby in FRC
in case anything goes awry.
362
00:23:32,033 --> 00:23:33,834
Alright, crank up hydraulics.
363
00:23:38,066 --> 00:23:40,934
Yeah, we definitely don't see
this in the Gulf of Mexico.
364
00:23:41,066 --> 00:23:42,400
(LAUGHS)
365
00:23:44,066 --> 00:23:46,934
They'll do a quick test
366
00:23:47,066 --> 00:23:48,700
to make sure all of our
settings are correct,
367
00:23:50,300 --> 00:23:52,166
and then send it
under the ice.
368
00:23:52,300 --> 00:23:53,633
This is the start of it here.
369
00:23:53,767 --> 00:23:55,967
MAN: AUV is in armed state.
Go ahead, Shane.
370
00:23:56,100 --> 00:23:57,667
BONIN: They put it
in armed state.
371
00:23:57,800 --> 00:23:59,433
It's armed and ready to go.
372
00:24:04,133 --> 00:24:06,400
MAN: AUV in the water.
BONIN: Like a torpedo.
373
00:24:08,800 --> 00:24:09,834
Alright. Looking good.
374
00:24:11,333 --> 00:24:12,500
FISHBURNE: All systems are go.
375
00:24:16,834 --> 00:24:18,734
Stay back here and monitor.
376
00:24:18,867 --> 00:24:20,266
Roger that. Ready to dive.
377
00:24:22,400 --> 00:24:23,967
Alright, 30 seconds
till it dives.
378
00:24:38,400 --> 00:24:39,834
Come on, cowboy.
379
00:24:43,133 --> 00:24:46,166
MAN OVER RADIO: It's not going
down. Start making some waves.
380
00:24:49,767 --> 00:24:51,834
JAMES: It's very, very flat.
381
00:24:51,967 --> 00:24:54,233
When it's flat calm like this,
it has a tough time diving.
382
00:24:56,133 --> 00:24:57,934
FISHBURNE: The only way
to make the AUV dive
383
00:24:58,066 --> 00:25:00,066
is to make their own waves.
384
00:25:00,200 --> 00:25:03,300
Go create that wake in
front of it as it's travelling.
385
00:25:03,433 --> 00:25:05,867
It's trying to get
the water on top of the bow,
386
00:25:06,000 --> 00:25:08,767
at the forward end of the AUV
to get it to start digging in.
387
00:25:14,667 --> 00:25:16,000
Go, baby, go.
388
00:25:23,033 --> 00:25:25,500
Keep coming,
you're making headway.
389
00:25:28,533 --> 00:25:30,133
It's going down, my man.

-(LAUGHING)
-Good job, fellas.
391
00:25:38,300 --> 00:25:40,166
BONIN: It took a little while,
but it started diving.
392
00:25:42,867 --> 00:25:45,000
So as of now, we have
a successful dive.
393
00:25:47,900 --> 00:25:49,667
It's a great relief to finally
get it under.
394
00:25:49,800 --> 00:25:51,667
We're on our first mission.
395
00:25:56,467 --> 00:25:58,700
FISHBURNE: Now it's over
to Devon's colleague,
396
00:25:58,834 --> 00:26:01,967
Blake Howard,
to communicate with the AUV.
397
00:26:03,867 --> 00:26:05,667
We can pull forward
a little more.
398
00:26:05,800 --> 00:26:07,967
AUV's getting down to
300 meters right now.
399
00:26:10,900 --> 00:26:13,100
Once the AUV gets going
on its pre-programmed
400
00:26:13,233 --> 00:26:14,300
four-hour test mission,
401
00:26:15,266 --> 00:26:17,300
Blake will have no control.
402
00:26:17,433 --> 00:26:19,266
All he can do is track it
with this,
403
00:26:21,967 --> 00:26:25,533
a high-precision acoustic
positioning system or HiPAP.

Dropped through the hull
into the sea,
406
00:26:35,467 --> 00:26:37,667
the HiPAP picks
up acoustic signals
407
00:26:37,800 --> 00:26:39,200
through the water from the sub.
408
00:26:42,433 --> 00:26:44,266
It even pulls in
some curious locals.

00:26:51,834 --> 00:26:53,667
While the team tracks
the AUV sub,

expedition archaeologist
Mensun Bound
412
00:26:57,867 --> 00:26:59,934
investigates how
Shackleton's ship
413
00:27:00,133 --> 00:27:05,033
ended up on this side of
the Weddell Sea a century ago.
414
00:27:05,166 --> 00:27:08,200
Here he is coming down the
coast of the Weddell Sea,
415
00:27:08,333 --> 00:27:11,133
all the while working his way
south, south.
416
00:27:11,266 --> 00:27:14,300
But as he's going, the ice is
becoming more and more dense
417
00:27:14,433 --> 00:27:15,834
and impenetrable,
418
00:27:15,967 --> 00:27:18,333
until eventually he gets all
the way down here.
419
00:27:18,467 --> 00:27:20,834
And right here is where
he becomes beset.
420
00:27:21,834 --> 00:27:25,667
FISHBURNE: Just 60 miles from
the south coast of the Weddell
421
00:27:25,800 --> 00:27:29,166
Sea, the ice pack freezes
solid around Shackleton's ship.
422
00:27:29,300 --> 00:27:31,600
The Endurance is trapped.
423
00:27:41,567 --> 00:27:43,567
HUSSEY: The temperature
suddenly dropped
424
00:27:43,700 --> 00:27:46,133
from 20 degrees above zero
to 20 degrees below it.
425
00:27:46,266 --> 00:27:48,967
The whole sea froze over
and we froze in with it.
426
00:27:49,100 --> 00:27:52,200
Of course, we had no explosives
to blast our way out.
427
00:27:52,333 --> 00:27:53,867
We just had picks and shovels.
428
00:27:55,834 --> 00:27:58,867
FISHBURNE: For 40 hours,
his men throw everything at it.
429
00:28:02,333 --> 00:28:04,200
But they can't free her
from the ice.
430
00:28:06,367 --> 00:28:10,734
And at that moment,
Shackleton's heart sank
431
00:28:10,867 --> 00:28:14,700
because he knew, because
it was so late in the season,
432
00:28:14,834 --> 00:28:16,333
that he was frozen
in place for winter.
433
00:28:19,000 --> 00:28:22,000
FISHBURNE: And in the six-month
long Antarctic winter,
434
00:28:22,133 --> 00:28:24,633
just staying alive
is nearly impossible.
435

00:28:28,367 --> 00:28:30,300
It's trying to kill you.
437
00:28:30,433 --> 00:28:33,400
That cold is physically painful.
438
00:28:33,533 --> 00:28:35,867
Any piece of exposed skin,
439
00:28:36,000 --> 00:28:38,233
just a little gap
in your clothing,
440
00:28:38,367 --> 00:28:40,633
that's like somebody cutting
your face with a knife.

00:28:40,767 --> 00:28:44,767
ANKER: The wind's unrelenting.
442
00:28:46,200 --> 00:28:48,500
And the snow is driven like
needles into your face.
443
00:28:51,433 --> 00:28:53,600
SCOTT: I was at
the South Pole, it was so cold.
444
00:28:53,734 --> 00:28:56,667
I removed my glove
for just about a minute,
445
00:28:56,800 --> 00:28:58,300
maybe a minute and 20 seconds,
446
00:28:58,433 --> 00:29:00,300
and my thumb froze solid.
447
00:29:00,433 --> 00:29:03,400
When you think about Shackleton
and his men, out there
448
00:29:03,533 --> 00:29:05,400
in wool and cotton
449
00:29:05,533 --> 00:29:07,800
and things that weren't really
designed for that environment,
450
00:29:12,066 --> 00:29:14,800
it just reminds me how tough
those men were.
451
00:29:19,834 --> 00:29:21,934
FISHBURNE: The Endurance
is completely stuck,
452
00:29:22,066 --> 00:29:25,900
but she's 550 miles from
where she will finally sink.
453
00:29:27,433 --> 00:29:29,066
So how did she get there?
454
00:29:32,300 --> 00:29:34,600
Turns out the Endurance
is still on the move...

(ICE CRACKING)
456
00:29:36,500 --> 00:29:39,133
...because the ice
is on the move.
457
00:29:39,266 --> 00:29:41,800
LARSEN: While it may
look like a land mass,
458
00:29:41,934 --> 00:29:43,867
it's floating on water.
459
00:29:46,433 --> 00:29:48,734
That means whatever
the water is doing,
460
00:29:48,867 --> 00:29:51,967
whatever the wind is doing,
that affects that surface.
461
00:29:54,266 --> 00:29:56,967
FISHBURNE: Strong currents
and winds in the Weddell Sea
462
00:29:57,100 --> 00:30:00,467
spin the entire ice pack
in a giant clockwise rotation.
463
00:30:03,467 --> 00:30:06,533
For ten months, the Endurance
moves with the ice.
464
00:30:12,967 --> 00:30:15,200
This is the route that
the Endurance was carried.
465
00:30:16,967 --> 00:30:20,467
We can follow the route
very precisely.
466
00:30:21,767 --> 00:30:23,000
The crew was trapped,
467
00:30:24,300 --> 00:30:27,867
but they had reason to believe
they would escape.
468
00:30:28,000 --> 00:30:29,667
Several years before,
another ship,
469
00:30:29,800 --> 00:30:31,200
a ship called
the Deutschland,
470
00:30:31,333 --> 00:30:33,700
had also become
beset down here.
471
00:30:33,834 --> 00:30:36,467
Because the Deutschland
was eventually released
472
00:30:36,600 --> 00:30:39,333
from the ice,
people on the Endurance
473
00:30:39,467 --> 00:30:41,367
thought the same thing
would happen to them.
474
00:30:46,533 --> 00:30:48,934
FISHBURNE: Out on deck in
the early hours of the morning,
475
00:30:49,066 --> 00:30:51,100
the team is waiting
for their AUV sub
476
00:30:51,233 --> 00:30:52,467
to return from its test run.
477
00:30:54,433 --> 00:30:55,700
But there's a problem.
478
00:30:55,834 --> 00:30:57,400
I don't know
what the hell's going on.
479
00:30:59,900 --> 00:31:02,367
They've lost all contact
with their brand new

FISHBURNE: Two weeks
into the expedition
482
00:31:24,133 --> 00:31:26,033
to find Shackleton's lost ship,
483
00:31:26,166 --> 00:31:29,333
the team is within striking
distance of the wreck site.
484
00:31:32,567 --> 00:31:34,033
But their ship
is going nowhere.
485
00:31:36,900 --> 00:31:39,066
Four hours into a test dive,
486
00:31:39,200 --> 00:31:41,834
AUV operator Blake Howard
lost contact
487
00:31:41,967 --> 00:31:45,033
with their multi-million dollar
drone submarine.
488
00:31:45,166 --> 00:31:48,900
Everything started to go well,
we were gaining confidence
489
00:31:49,033 --> 00:31:52,233
and then we lost it.
490
00:31:58,033 --> 00:32:01,200
When we saw that it did not
surface in front of us
491
00:32:02,600 --> 00:32:04,000
or to either side of us,
492
00:32:05,767 --> 00:32:08,433
we figured it had to be
in the ice.
493
00:32:08,567 --> 00:32:11,000
FISHBURNE: The fear is that
the AUV came up
494
00:32:11,133 --> 00:32:14,166
underneath the seven-mile wide
ice floe it was diving under.
495
00:32:20,200 --> 00:32:21,567
The team needs to move fast.
496
00:32:23,767 --> 00:32:26,734
The AUV has 54 hours
of battery.
497
00:32:26,867 --> 00:32:30,433
If the battery dies,
they'll never get it back.
498
00:32:30,567 --> 00:32:33,333
That's a multi-million dollar
loss they can't take.
499
00:32:34,767 --> 00:32:36,233
We're going to search
that area right there.
500
00:32:38,266 --> 00:32:40,533
The expedition throws everyone
501
00:32:40,667 --> 00:32:43,066
and everything they've got
into the hunt.
502
00:32:44,934 --> 00:32:46,166
Boats,
503
00:32:48,100 --> 00:32:49,433
aerial drones,
504
00:32:51,934 --> 00:32:53,700
and the operated vehicles.
505
00:32:55,233 --> 00:32:58,600
The AUV has two flashers on it
506
00:32:58,734 --> 00:33:01,900
and the general idea is
to get the ROV down deep,
507
00:33:02,033 --> 00:33:04,967
turn off all our lights,
and hopefully see those beacons.
508
00:33:08,166 --> 00:33:09,600
MAN OVER RADIO: Okay,
Steve, go into the water.
509
00:33:09,734 --> 00:33:10,934

You know something?
519

There is no way we're
even gonna see a flasher.

of algae beneath the ice
521
00:33:52,467 --> 00:33:55,734
has reduced
visibility to almost zero.
522
00:34:07,500 --> 00:34:09,266

see anything.

come back.

I'm very worried.
526
00:34:23,867 --> 00:34:26,967
From day one we recognized
that our nemesis
527
00:34:27,100 --> 00:34:28,433
was going to be the ice pack.
528
00:34:28,567 --> 00:34:30,767
You know, just as
it was Shackleton's,
529
00:34:30,900 --> 00:34:32,900
so was it going to be ours.
530
00:34:33,033 --> 00:34:35,800
And, I'll tell you what,
it's proven to be just that.
531

FISHBURNE: It's a setback,
532
00:34:41,667 --> 00:34:43,266
but the team can't afford
to give up.
533
00:34:48,066 --> 00:34:49,700
Sixteen hours later,
534
00:34:52,900 --> 00:34:55,934
Blake finally detects a signal
from the missing AUV sub.
535
00:35:01,633 --> 00:35:02,934
I started looking at everything
536
00:35:03,066 --> 00:35:05,900
and I saw that 45 minutes ago
537
00:35:06,033 --> 00:35:09,200
there was a HiPAP hit that made
contact somewhere nearby.
538
00:35:12,200 --> 00:35:15,100
FISHBURNE: The sub is within
a mile of the of the ship,
539
00:35:15,233 --> 00:35:17,100
somewhere under the ice.
540
00:35:17,233 --> 00:35:19,500
The first ping, when it
actually did come through,
541
00:35:19,633 --> 00:35:21,433
was a great feeling
for everybody.
542
00:35:21,567 --> 00:35:23,700
It's extremely
exciting for her
543
00:35:23,834 --> 00:35:25,834
to actually
talk back to us,
544
00:35:25,967 --> 00:35:28,333
and it gave us a direction
to head towards.
545
00:35:29,967 --> 00:35:32,567
FISHBURNE: But with
only one acoustic hit,
546
00:35:32,700 --> 00:35:35,900
team leader Channing Thomas
can't get an accurate fix.
547
00:35:37,133 --> 00:35:39,467
He needs his team
to generate more hits
548
00:35:39,600 --> 00:35:41,633
to zero in on the AUV
sub's location.
549
00:35:43,633 --> 00:35:45,066
That means a radical makeover
550
00:35:45,200 --> 00:35:46,834
to their underwater
comms system.
551
00:35:48,133 --> 00:35:50,667
What we need to do is
create a 45-degree angle,
552
00:35:50,800 --> 00:35:54,533
so the HiPAP is facing
outwards instead of downwards.
553
00:36:04,767 --> 00:36:06,767
FISHBURNE: Making
the comms system face forward
554
00:36:06,900 --> 00:36:09,000
is something they've
never tried before.

00:36:09,133 --> 00:36:10,133

one HiPAP on this ship

to be quite robust,
559
00:36:21,100 --> 00:36:23,200
in fact, it's not.
560
00:36:23,333 --> 00:36:26,100
If we take just
one knock from an ice floe,
561
00:36:26,233 --> 00:36:28,033
that's it.
It's game over.

(SONAR BEEPING CONTINUES)
566
00:36:45,133 --> 00:36:47,700
FISHBURNE: Then the team
picks up a response.
567
00:36:52,433 --> 00:36:54,767
It's almost
definitely a hit,
568
00:36:54,900 --> 00:36:57,800
so it's got to
be within range.
569
00:37:01,166 --> 00:37:03,867
You know, we know
we're within its range.
570

more new signals.

three different locations
576
00:37:21,800 --> 00:37:24,433
to triangulate
about where she's located
577
00:37:24,567 --> 00:37:26,700
and we're figuring she's
about 800 meters ahead.

an exact location,

target zone.

FISHBURNE: Half a mile
might seem close,
581

needs to get closer.

from the ship.

00:45:18,233 --> 00:45:19,667
-You got a hold of it?
-Yep.
682
00:45:19,800 --> 00:45:20,867
Alright,
back down a little bit.
683
00:45:22,500 --> 00:45:23,567
Whoo!
684
00:45:23,700 --> 00:45:25,066
That's cold, buddy.
685
00:45:26,967 --> 00:45:31,233
FISHBURNE: After a very
close call, the AUV is safe.
686
00:45:35,567 --> 00:45:37,333
Alright, coming up easy.
687
00:45:41,633 --> 00:45:42,867
We're good.
688
00:45:45,867 --> 00:45:46,934
Got it, Paul.
689
00:45:48,500 --> 00:45:49,667
(LAUGHS) That's it.
690
00:45:49,800 --> 00:45:51,500
I'm just glad to
have it on board.
691
00:45:53,800 --> 00:45:56,467
JAMES: It's been a rough
four or five days,
692
00:45:56,600 --> 00:45:58,800
so it will be nice to actually
get a full night's sleep
693
00:45:58,934 --> 00:46:00,433
instead of a few hours
here and there.
694
00:46:03,233 --> 00:46:05,200
FISHBURNE: With the critical
gear now on board,
695
00:46:05,333 --> 00:46:06,834
the hunt for the wreck
is back on.
696
00:46:07,767 --> 00:46:09,166
BOUND: Yeah, this is great.
697
00:46:09,300 --> 00:46:13,433
Having her back on board
like this, it's the best.
698
00:46:13,567 --> 00:46:14,967
FISHBURNE: The team can
now press ahead.
699
00:46:17,834 --> 00:46:19,767
But there's still 230 miles
700
00:46:19,900 --> 00:46:21,734
from where Shackleton's
ship went down.
701
00:46:24,667 --> 00:46:28,433
And in that area, the sea is
still entirely covered in ice.
702
00:46:30,967 --> 00:46:34,633
Shackleton and his ship
drifted into this northwestern
703
00:46:34,767 --> 00:46:37,967
part of the Weddell Sea,
in October 1915.
704
00:46:41,600 --> 00:46:44,834
For 10 long months,
they've been locked in the ice
705
00:46:44,967 --> 00:46:46,600
in a bitter struggle
for survival.
706
00:46:48,500 --> 00:46:49,867
It's so damn cold.
707
00:46:51,533 --> 00:46:55,233
If you don't have an elaborate
safety net of equipment,
708
00:46:55,800 --> 00:46:57,000
you'll die.
709
00:46:58,767 --> 00:47:01,834
FISHBURNE: Shackleton's
only safety net is his ship,
710
00:47:01,967 --> 00:47:04,533
but now the mounting
pressure in the ice
711
00:47:04,667 --> 00:47:05,967
is breaking it apart.
712
00:47:08,367 --> 00:47:11,367
LARSON: They're in the ship,
they can hear this ice
713
00:47:11,500 --> 00:47:12,734
moving against the ship.
714
00:47:12,867 --> 00:47:14,734
You hear the creaking
of the ship.
715
00:47:14,867 --> 00:47:17,467
You hear the pressure
on the joints.
716
00:47:17,600 --> 00:47:20,667
You never know if the ship's
just gonna break apart.
717
00:47:20,800 --> 00:47:22,633
(RUMBLING AND CRACKING)
718
00:47:22,767 --> 00:47:26,100
HOWE: The timbers began
to crack and groan.
719
00:47:26,233 --> 00:47:29,100
It was like heavy fireworks
and the blasting of guns.
720
00:47:31,567 --> 00:47:33,667
(RUMBLING INTENSIFIES)
721
00:47:41,000 --> 00:47:42,834
ANKER: To see
the pack ice move in
722
00:47:42,967 --> 00:47:47,667
and just squeeze the life
out of that boat,
723
00:47:47,800 --> 00:47:54,667
it must have been so trying
and so depressing.
724
00:47:57,266 --> 00:47:59,500
FISHBURNE:
Mother Nature overwhelms
725
00:47:59,633 --> 00:48:01,834
the mighty Endurance.
726
00:48:04,000 --> 00:48:07,400
Finally, Shackleton gives
the order to abandon ship.
727
00:48:11,400 --> 00:48:13,467
ANKER: Their only hope
was to take everything off
728
00:48:13,600 --> 00:48:15,433
that ship that they needed,
729
00:48:15,567 --> 00:48:18,333
and put it on their rescue
boats and then
730
00:48:18,467 --> 00:48:20,567
switch into survival mode.
731
00:48:22,734 --> 00:48:25,700
FISHBURNE: The 28 men
and 49 dogs
732
00:48:25,834 --> 00:48:29,800
can only watch as
the Endurance is overwhelmed.
733
00:48:29,934 --> 00:48:31,533
(TIMBER CRACKING)
734
00:48:34,467 --> 00:48:37,000
I can only image what it was
like for him when he sat there
735
00:48:37,133 --> 00:48:39,834
and stood on the ice and watched
it just slowly implode.
736
00:48:43,400 --> 00:48:45,266
Just a piece of his
heart and soul
737
00:48:45,400 --> 00:48:47,000
probably went down
with that ship when it went.
738
00:48:51,700 --> 00:48:54,900
FISHBURNE: The ship disappears
beneath the surface.
739
00:48:59,800 --> 00:49:02,400
Shackleton and his men
are truly alone.
740
00:49:03,934 --> 00:49:07,867
I think they were much more
lonely than I was on Apollo 13,
741
00:49:08,000 --> 00:49:11,800
because I had
communication with home.
742
00:49:11,934 --> 00:49:15,200
Shackleton, he didn't have
a radio, he didn't have wi-fi,
743
00:49:15,333 --> 00:49:17,533
didn't have, you know,
a cellphone.
744
00:49:18,066 --> 00:49:20,100
He was alone.
745
00:49:22,700 --> 00:49:24,600
FISHBURNE: Shackleton's
dream of becoming
746
00:49:24,734 --> 00:49:26,767
the first man
to cross Antarctica
747
00:49:26,900 --> 00:49:30,066
is ultimately crushed
along with his ship.
748
00:49:34,700 --> 00:49:38,934
This is where his real battle
for survival begins.
749
00:49:47,367 --> 00:49:49,633
But if the ice crushed
Shackleton's ship,
750
00:49:49,767 --> 00:49:52,500
what can the team expect
to find on the sea floor?
751
00:49:54,433 --> 00:49:57,166
Mensun Bound is searching
for clues in the records.
752
00:49:58,233 --> 00:50:01,133
BOUND: You see in this
picture here, the stern rose up
753
00:50:01,266 --> 00:50:04,000
45 degrees, the bow
went even further down
754
00:50:04,133 --> 00:50:07,567
and then she just slid
and was gone in minutes.
755
00:50:07,700 --> 00:50:10,000
FISHBURNE:
The Endurance then dives
756
00:50:10,133 --> 00:50:12,533
10,000 feet
to the sea floor.
757
00:50:15,000 --> 00:50:16,433
But Mensun spots evidence
758
00:50:16,567 --> 00:50:19,133
that the wooden ship likely
survived the impact.
759
00:50:21,300 --> 00:50:23,867
All this clutter that you see
in this picture here,
760
00:50:24,000 --> 00:50:26,333
all these masts and yards,
761
00:50:26,467 --> 00:50:29,266
all that was still attached to
the ship when it went down,
762
00:50:29,400 --> 00:50:31,633
and that would have
imposed an incredible
763
00:50:31,767 --> 00:50:34,100
drag on the sinking ship.
764
00:50:34,233 --> 00:50:36,367
That would've kept her upright
and would to some extent
765
00:50:36,500 --> 00:50:37,600
have slowed her down.
766
00:50:38,834 --> 00:50:41,367
I do believe
that the ship itself
767
00:50:41,500 --> 00:50:44,800
is likely to be
in an upright state,
768
00:50:44,934 --> 00:50:47,700
but also
three-dimensionally intact.
769
00:50:51,467 --> 00:50:53,834
FISHBURNE: It's promising news
for the rest of the team.
770
00:50:56,533 --> 00:50:58,533
But suddenly,
there's a new problem.
771
00:50:59,900 --> 00:51:02,467
This time it's not the AUV sub,
772
00:51:02,600 --> 00:51:04,934
but the robot that's supposed
to explore the wreck.
773
00:51:05,700 --> 00:51:07,800
The pod's gone.
774
00:51:07,934 --> 00:51:10,133
FISHBURNE: It looks like
it's suffered a death blow.
775
00:51:29,633 --> 00:51:31,934
FISHBURNE: Halfway into
their mission time,
776
00:51:32,066 --> 00:51:34,967
the team in Antarctica
is under mounting pressure
777
00:51:35,100 --> 00:51:38,367
to reach the site
of Ernest Shackleton's wreck.
778
00:51:38,500 --> 00:51:41,834
Engineers Steve Saint Amour
and Dave O'Hara
779
00:51:41,967 --> 00:51:44,166
are depth testing
their underwater robot
780
00:51:44,300 --> 00:51:45,800
so it's ready to go.
781
00:51:47,567 --> 00:51:49,033
But something's not right.
782
00:51:51,633 --> 00:51:53,033
Guys, we're gonna bring it back.
783
00:52:03,533 --> 00:52:05,600
The pod's gone.
784
00:52:05,734 --> 00:52:08,500
FISHBURNE: A critical part
has imploded under the extreme
785
00:52:08,633 --> 00:52:11,266
pressure, ten thousand
feet below the surface.
786
00:52:13,333 --> 00:52:17,233
The robot's electronic brain
is now mangled metal.
787
00:52:17,367 --> 00:52:19,133
We've had
a catastrophic failure.
788
00:52:20,767 --> 00:52:24,266
We don't have all the
electronics to rebuild the ROV.
789
00:52:26,367 --> 00:52:29,166
I don't know what to say,
really, I just don't.
790
00:52:29,300 --> 00:52:30,467
Yeah, I'm speechless.
791
00:52:33,533 --> 00:52:36,300
FISHBURNE: The aluminum
pod was designed to withstand
792
00:52:36,433 --> 00:52:39,000
pressure nearly three
miles below the surface.
793
00:52:39,667 --> 00:52:41,600
But Steve thinks
the combination of extreme cold
794
00:52:41,734 --> 00:52:43,700
and a material flaw
795
00:52:43,834 --> 00:52:45,533
has caused it to be crushed
796
00:52:45,667 --> 00:52:48,266
like it was nothing
more than a soda can.
797
00:52:49,333 --> 00:52:50,500
This is what we found.
798
00:52:50,633 --> 00:52:51,967
One half of the bottle
has pancaked
799
00:52:52,100 --> 00:52:54,033
into the other half
of the bottle.
800
00:52:54,166 --> 00:52:56,300
There were
quite substantial electronics
801
00:52:56,433 --> 00:52:58,567
and they are entirely crushed.
802
00:52:58,700 --> 00:53:00,300
This is the first time
in my career
803
00:53:00,433 --> 00:53:02,000
that I've ever seen
this first hand.
804
00:53:02,133 --> 00:53:04,467
This is an example of what
hydraulic pressure can do.
805
00:53:07,467 --> 00:53:10,000
FISHBURNE: It's a bitter blow
for expedition archaeologist
806
00:53:10,133 --> 00:53:11,333
Mensun Bound.
807
00:53:12,100 --> 00:53:14,000
The worst possible news.
808
00:53:14,133 --> 00:53:17,066
I mean, to lose our electronics
like that.
809
00:53:17,200 --> 00:53:19,100
There is no replacement.
810
00:53:19,233 --> 00:53:21,133
We can't fly in spare parts.
811
00:53:21,266 --> 00:53:24,100
There's nothing we can do.
812
00:53:24,233 --> 00:53:26,800
This was what I was going to
use to study the wreck, really,
813
00:53:26,934 --> 00:53:28,667
eyeball to eyeball
with the wreck.
814
00:53:37,667 --> 00:53:39,867
FISHBURNE: To add
to the problems on deck,
815
00:53:40,000 --> 00:53:42,367
the bridge has discovered
their closest route
816
00:53:42,500 --> 00:53:46,400
to the wreck site is now
totally shut off by the ice.
817
00:53:47,400 --> 00:53:49,834
Analyzing daily satellite
photographs,
818
00:53:49,967 --> 00:53:54,066
ice pilot Freddie Ligthelm
is hunting for another way in.
819
00:53:55,767 --> 00:53:59,900
He's looking for channels
of open water called leads
820
00:54:00,100 --> 00:54:03,433
on the other side
of the pack ice.
821
00:54:05,633 --> 00:54:08,266
LIGTHELM: It does appear that
there's some leads opening
822
00:54:08,400 --> 00:54:11,066
up in that area, so we're
quite excited about that.
823
00:54:12,467 --> 00:54:14,834
We can actually approach
the search site coming right
824
00:54:14,967 --> 00:54:18,867
around all the ice and
approaching from the south east.
825
00:54:19,000 --> 00:54:22,867
With a bit of luck,
we can be cautiously optimistic.
826
00:54:24,200 --> 00:54:27,033
FISHBURNE: The new plan
is to go the long way round,
827
00:54:28,600 --> 00:54:31,567
skirt the pack ice, and then
head towards the wreck site.
828
00:54:35,433 --> 00:54:37,567
With a clear path
ahead of them,
829
00:54:37,700 --> 00:54:39,500
the ship should be able
to reach the wreck site
830
00:54:39,633 --> 00:54:41,133
in a matter of days.
831
00:54:42,934 --> 00:54:45,100
Out on the deck,
the AUV team
832
00:54:45,233 --> 00:54:47,266
is making
their final preparations.
833
00:54:49,266 --> 00:54:52,000
All hopes now rest on them
to find the wreck.
834
00:54:53,667 --> 00:54:55,300
BONIN: I'm excited about it.
835
00:54:55,433 --> 00:54:58,100
Can't beat the smile off my
face right now, you know.
836
00:54:58,233 --> 00:54:59,533
Finally getting there.
837
00:55:02,066 --> 00:55:04,066
To be in the same area
where he was at
838
00:55:04,200 --> 00:55:07,467
and to finally locate that ship
is just...
839
00:55:10,300 --> 00:55:13,367
It's an excitement
that I really can't explain.
840
00:55:13,500 --> 00:55:15,533
FISHBURNE: Finding Shackleton's
ship is the ultimate goal
841
00:55:15,667 --> 00:55:17,533
of this expedition.
842
00:55:21,133 --> 00:55:23,467
But 100 years ago,
losing the Endurance
843
00:55:23,600 --> 00:55:25,233
was just the start of a journey
844
00:55:25,367 --> 00:55:28,000
that would make
Ernest Shackleton a legend.
845
00:55:34,967 --> 00:55:36,266
Stranded on the ice,
846
00:55:36,400 --> 00:55:38,367
Shackleton's men face
impossible odds,
847
00:55:40,100 --> 00:55:43,200
but they have blind faith
in the man they call The Boss.
848
00:55:44,600 --> 00:55:48,567
There's this classic quote,
and to paraphrase it,
849
00:55:48,700 --> 00:55:51,066
"When the chips are down
and all hope is gone,
850

"get down on your knees
and pray for Shackleton."
851
00:55:56,100 --> 00:55:58,400
FISHBURNE: Shackleton orders
his men to march for land,
852
00:55:58,533 --> 00:56:00,567
two hundred miles
across the ice.
853
00:56:03,600 --> 00:56:08,200
Shackleton has
these massive sleds
854
00:56:08,333 --> 00:56:12,133
with full wooden boats on them
loaded with supplies.
855
00:56:16,100 --> 00:56:20,033
And you could come up to
a massive pressure ridge,
856
00:56:20,166 --> 00:56:23,300
blocks of ice
as big as semi-trucks
857
00:56:23,433 --> 00:56:26,200
that are shoved
up into the air
858
00:56:26,333 --> 00:56:28,133
ten, 15, 20 feet,
859
00:56:28,266 --> 00:56:29,867
and so,
as you're approaching it,
860
00:56:30,000 --> 00:56:31,834
it basically is a wall of ice.
861
00:56:33,633 --> 00:56:35,734
I mean, I don't like to say
things are impossible,
862
00:56:35,867 --> 00:56:38,367
but I don't know how they
would get over that stuff.
863
00:56:38,500 --> 00:56:40,633
(DOGS BARKING)
864
00:56:40,767 --> 00:56:42,633
FISHBURNE: The men
cover only nine miles
865
00:56:42,767 --> 00:56:44,533
of pack ice in
a week.
866
00:56:46,200 --> 00:56:50,333
Shackleton realizes
reaching land is impossible.
867
00:56:50,467 --> 00:56:54,734
To make matters worse, they're
slowly starving to death.
868
00:56:55,500 --> 00:56:58,333
As food supplies run out,
they're forced to eat
869
00:56:58,467 --> 00:57:01,266
the only things that brought
them joy in the wilderness,
870
00:57:02,133 --> 00:57:04,333
their dogs.
871
00:57:04,467 --> 00:57:07,934
ANKER: The companionship
that the dogs provided the team
872
00:57:08,066 --> 00:57:11,166
was quite significant.
873
00:57:11,300 --> 00:57:17,266
That moment must have been hard
in an emotional point,
874
00:57:17,400 --> 00:57:21,467
but it was also a mirror
of how extended they were
875
00:57:21,600 --> 00:57:23,900
and how precarious life was.
876
00:57:24,300 --> 00:57:26,700
If you're shooting
your dogs,
877
00:57:26,834 --> 00:57:28,633
you're on the down and outs.
878
00:57:33,266 --> 00:57:35,433
FISHBURNE: Then,
as the ice they're on
879
00:57:35,567 --> 00:57:36,967
drifts closer
to the open ocean,
880
00:57:38,600 --> 00:57:41,567
it starts to break apart
beneath them.

(CRACKING AND RUMBLING)
882
00:57:49,533 --> 00:57:52,066
And they have to rush
onto their boats.
883

They have to throw
their things on their boats.
884
00:57:54,400 --> 00:57:56,834
They have to get
into these boats
885
00:57:56,967 --> 00:57:59,533
with everything they need
to survive.
886
00:57:59,667 --> 00:58:04,367
They have no choice,
but to go from relative safety
887
00:58:05,600 --> 00:58:07,033
to basically certain death.
888
00:58:09,600 --> 00:58:11,867
FISHBURNE: Shackleton
has finally left the ice
889
00:58:12,000 --> 00:58:13,767
that's trapped him
for 15 months.
890
00:58:15,400 --> 00:58:19,800
But now he faces a new danger,
the open Weddell Sea.
891
00:58:25,233 --> 00:58:27,800
Even today this sea is nearly
impossible to navigate,
892
00:58:30,033 --> 00:58:32,700
as the crew of the Agulhas II
is finding out.
893
00:58:35,934 --> 00:58:37,700
We are now just stuck.
894
00:58:57,734 --> 00:59:01,000
FISHBURNE: To reach the site
of Ernest Shackleton's wreck,
895
00:59:01,133 --> 00:59:03,600
the Agulhas II has powered
around the ice pack
896
00:59:03,734 --> 00:59:05,333
at the heart
of the Weddell Sea.
897
00:59:07,033 --> 00:59:10,200
And she's smashed through
thick ice for the last 24 hours.
898
00:59:15,000 --> 00:59:18,033
But just 19 miles from where
the Endurance sank,
899
00:59:18,166 --> 00:59:21,033
the Agulhas II runs
into serious trouble.

She's stuck in the ice
just like Shackleton's ship.

BOUND: We're stuck.
We're in a white out.
903
00:59:42,734 --> 00:59:45,133
The ice is well over
three meters thick,
904
00:59:45,266 --> 00:59:47,166
possibly even as much as five,
905
00:59:47,300 --> 00:59:49,767
and we're way, way below zero.
906
00:59:52,633 --> 00:59:54,367
FISHBURNE: In the early
hours of the morning,
907
00:59:54,500 --> 00:59:58,967
the ship was brought to a
standstill by impenetrable fog.
908
00:59:59,100 --> 01:00:02,567
The ice moved in around her
and froze her in.
909
01:00:06,867 --> 01:00:08,567
If the temperature
drops further,
910
01:00:08,700 --> 01:00:10,667
the ice could trap the crew
for days,
911
01:00:10,800 --> 01:00:12,467
and the harsh Antarctic winter
912
01:00:12,600 --> 01:00:15,233
is already
barrelling down on them.
913
01:00:15,367 --> 01:00:17,633
But Devon's got an idea.
914
01:00:17,767 --> 01:00:19,900
JAMES: We could do like
Shackleton did on the Endurance
915
01:00:20,033 --> 01:00:22,133
when they got stuck in
the ice and had the whole crew
916
01:00:22,266 --> 01:00:24,000
run from one side
of the vessel to the other,
917
01:00:24,133 --> 01:00:26,100
together,
to rock the ship free.
918
01:00:32,166 --> 01:00:34,000
FISHBURNE: Devon's half kidding
919
01:00:34,133 --> 01:00:36,300
but his plan
isn't as crazy as it sounds.
920
01:00:38,333 --> 01:00:42,600
Captain Bengu has 18 years'
experience in Antarctic ice
921
01:00:42,734 --> 01:00:45,300
and he's got a 21st-century
trick up his sleeve.
922
01:00:48,266 --> 01:00:51,533
Instead of moving his crew
from one side to the other,
923
01:00:51,667 --> 01:00:54,000
he's shifting a 40-ton
container of fuel
924
01:00:57,300 --> 01:00:58,600
using his crane.

the Captain has a clear view
of the route ahead.

And the closer they get,
the thicker the ice becomes.

is Shackleton territory.

it's gnarled,
it's all hummocked

It can sink a vessel
in seconds.

and you skid down.

are stacked against them,
1007

but Shackleton knows if
he doesn't make it to land,

I only got two hours' sleep,
I'm shattered,
1020
01:07:13,333 --> 01:07:16,800
but, you know, at the same time
I'm really happy.
1021
01:07:16,934 --> 01:07:20,000
But, you know,
we've still got to find it.
1022
01:07:20,133 --> 01:07:23,767
To actually
be here and able to
1023
01:07:23,900 --> 01:07:26,567
be part of the search
is very exciting.
1024
01:07:26,700 --> 01:07:28,433
I'm ready for it.
1025
01:07:28,567 --> 01:07:31,233
FISHBURNE: But can they
reach the Endurance?
1026
01:07:33,700 --> 01:07:35,700
JAMES: Hit the hydraulics.
1027
01:07:35,834 --> 01:07:38,300
FISHBURNE: The challenges of
getting down to the wreck...
1028
01:07:38,433 --> 01:07:40,166
What have you got?
1029
01:07:40,300 --> 01:07:42,834
...will put the mission
on the line.
1030
01:07:42,967 --> 01:07:44,133
The battery's running out.
1031
01:08:02,200 --> 01:08:05,633
FISHBURNE: Deep within the
iciest part of the Weddell Sea,
1032
01:08:05,767 --> 01:08:08,367
against all odds,
1033
01:08:08,500 --> 01:08:11,000
the expedition to
find Shackleton's wreck
1034
01:08:13,400 --> 01:08:16,166
has broken through
to the actual site
1035
01:08:16,300 --> 01:08:18,734
where the ship sank
over a 100 years ago.
1036
01:08:21,834 --> 01:08:25,667
Steve and Dave's robot sub
is out of the game.
1037
01:08:25,800 --> 01:08:28,433
Damaged beyond repair,
it can't hunt the wreck.
1038
01:08:29,500 --> 01:08:32,400
But there's still the AUV sub,
1039
01:08:32,533 --> 01:08:35,367
which will use sonar
to scan the sea floor.
1040
01:08:36,867 --> 01:08:40,400
We're close to the actual
last known location
1041
01:08:40,533 --> 01:08:42,800
of the Endurance.
1042
01:08:42,934 --> 01:08:44,533
We're gonna launch
from where we're at,
1043
01:08:44,667 --> 01:08:46,767
all the way down to
3,000 meters, to the bottom.
1044
01:08:48,667 --> 01:08:50,367
Hopefully everything works well,
1045
01:08:50,500 --> 01:08:53,333
according to plan,
and we'll see what happens.
1046
01:08:58,500 --> 01:09:01,934
FISHBURNE: Existing scans
reveal that the Agulhas II
1047
01:09:02,066 --> 01:09:05,800
is floating above
a vast underwater plain.
1048
01:09:07,800 --> 01:09:09,600
Here the sea floor plunges down
1049
01:09:09,734 --> 01:09:11,900
forty times the height
of Niagara Falls,
1050
01:09:12,033 --> 01:09:14,233
to a depth of 10,000 feet.
1051
01:09:15,533 --> 01:09:18,800
This is the deepest zone
of the Weddell Sea,
1052
01:09:18,934 --> 01:09:21,600
and the crew believes
this plain
1053
01:09:21,734 --> 01:09:24,767
is the final resting ground
of Shackleton's ship.
1054
01:09:28,033 --> 01:09:30,166
To program
their sub's flight path,
1055
01:09:30,300 --> 01:09:32,333
the team needs to know
what the water conditions
1056
01:09:32,467 --> 01:09:34,667
are like at the sea floor.
1057
01:09:34,800 --> 01:09:36,400
(WHIRRING)
1058
01:09:37,734 --> 01:09:41,066
They deploy a monitoring device
called a CTD
1059
01:09:41,934 --> 01:09:43,734
to analyze the water.
1060
01:09:50,467 --> 01:09:52,867
Somewhere
in these icy depths,
1061
01:09:53,000 --> 01:09:54,700
ten thousand feet down,
1062
01:09:57,433 --> 01:09:59,900
lie the remains
of Shackleton's ship.
1063
01:10:02,533 --> 01:10:04,533
Mensun Bound wants to know
1064
01:10:04,667 --> 01:10:06,433
what the data
might also tell him
1065
01:10:06,567 --> 01:10:08,900
about the condition
of the wreck.
1066
01:10:09,033 --> 01:10:10,800
Hey, guys, what have you got?
1067
01:10:10,934 --> 01:10:12,600
This is the CTD
over the wreck site
1068
01:10:12,734 --> 01:10:14,233
and it's just got to
the bottom,
1069
01:10:14,367 --> 01:10:16,700
so we're at about
just over 3,000 meters.
1070
01:10:16,834 --> 01:10:18,500
And as we get
right to the bottom,
1071
01:10:18,633 --> 01:10:21,834
sort of in the last couple
of hundred meters,
1072
01:10:21,967 --> 01:10:25,433
the temperature
goes down considerably.
1073
01:10:25,567 --> 01:10:27,467
FISHBURNE:
Remarkably, the water
1074
01:10:27,600 --> 01:10:30,266
at the sea floor
is below 32 degrees.
1075
01:10:32,133 --> 01:10:36,667
It doesn't freeze solid because
of the vast pressures at depth.
1076
01:10:36,800 --> 01:10:40,333
BOUND: Depth combined
with the super cold water,
1077
01:10:40,467 --> 01:10:42,834
any bacterial activity
will be slowed down.
1078
01:10:42,967 --> 01:10:44,367
This is all pretty good news
1079
01:10:44,500 --> 01:10:46,433
for the preservation
of the Endurance.
1080
01:10:52,000 --> 01:10:55,133
FISHBURNE: All they've got to
do now is launch the AUV sub
1081
01:10:55,266 --> 01:10:56,867
to hunt it down.
1082
01:10:57,000 --> 01:10:59,567
Hit that hydraulics
when you walk around.
1083
01:11:00,567 --> 01:11:03,400
But all the ice here
is a problem.
1084
01:11:03,533 --> 01:11:06,834
The AUV normally needs an open
run of several hundred feet
1085
01:11:06,967 --> 01:11:08,367
to get below the water.
1086
01:11:11,333 --> 01:11:13,367
To make it sink faster,
1087
01:11:13,500 --> 01:11:16,700
Devon and Blake are trying out
an unusual solution,
1088
01:11:16,834 --> 01:11:20,033
using a bag of salt
to add weight.
1089
01:11:23,066 --> 01:11:25,400
But will their
improvised fix work
1090
01:11:25,533 --> 01:11:27,500
when it comes to
the actual launch?
1091
01:11:29,567 --> 01:11:32,300
JAMES: I've added
five kilos of salt.
1092
01:11:32,433 --> 01:11:35,600
Salt should help it get down
in this flat calm water
1093
01:11:35,734 --> 01:11:37,900
and get down to bottom,
and start tracking.
1094
01:11:39,100 --> 01:11:40,700
Ready for armed state.
1095
01:11:51,700 --> 01:11:52,934
It's heavy.
1096
01:11:53,066 --> 01:11:55,367
Alright.
1097
01:11:55,500 --> 01:11:57,133
FISHBURNE: Adding the salt
is a success.
1098
01:11:59,567 --> 01:12:02,834
The propellers bite
and the AUV dives.
1099
01:12:08,500 --> 01:12:12,400
That was a successful launch
for the first mission
1100
01:12:12,533 --> 01:12:15,533
to search for the Endurance.
1101
01:12:15,667 --> 01:12:17,400
If all goes well
on the mission plan,
1102
01:12:17,533 --> 01:12:20,734
we should be recovering
in about 42-43 hours.
1103
01:12:22,934 --> 01:12:25,033
JAMES: If it's down there,
we should be able to find it.
1104
01:12:25,166 --> 01:12:27,066
Fingers crossed.
1105
01:12:31,000 --> 01:12:33,367
FISHBURNE: So far, so good.
1106
01:12:33,500 --> 01:12:35,433
The plan now is for the AUV
1107
01:12:35,567 --> 01:12:38,700
to spend the next 43 hours
away from the ship
1108
01:12:38,834 --> 01:12:42,433
on a pre-programmed route
beneath the ice.
1109
01:12:42,567 --> 01:12:46,500
At the moment we've just got
to depth, almost 3,000 meters,
1110
01:12:46,633 --> 01:12:48,967
and we just got comms
with the AUV.
1111
01:12:49,233 --> 01:12:51,800
Everything's good. She's
where she's supposed to be.
1112
01:12:54,834 --> 01:12:57,100
FISHBURNE: Channing's
team checks in with the AUV
1113
01:12:57,233 --> 01:13:00,300
at regular intervals
using the underwater
1114
01:13:00,433 --> 01:13:02,200
acoustic comms system.
1115
01:13:04,567 --> 01:13:08,233
That's a very big relief
that she's not
1116
01:13:08,367 --> 01:13:09,767
given us issues
underneath the ice.
1117
01:13:09,900 --> 01:13:11,867
So everything's looking good
at the moment.
1118
01:13:12,000 --> 01:13:14,467
We're gonna
keep our fingers crossed
1119
01:13:14,600 --> 01:13:16,667
and keep thinking positive
and keep pushing forward.
1120
01:13:18,967 --> 01:13:21,500
FISHBURNE: Now the ship
must follow the AUV
1121
01:13:21,633 --> 01:13:23,433
no matter how thick the ice.
1122
01:13:26,867 --> 01:13:29,567
After over 100 years,
1123
01:13:29,700 --> 01:13:31,433
the hunt for Shackleton's wreck
1124
01:13:31,567 --> 01:13:36,066
comes down to what happens
in the next 40 hours.
1125
01:13:51,767 --> 01:13:54,166
FISHBURNE: The team
has succeeded in reaching
1126
01:13:54,300 --> 01:13:57,700
the exact place Sir Ernest
Shackleton lost his ship.
1127
01:13:59,166 --> 01:14:01,800
Now can they find it?
1128
01:14:01,934 --> 01:14:04,533
Ten thousand feet down,
the AUV sub
1129
01:14:04,667 --> 01:14:06,800
is halfway
through its mission.
1130
01:14:06,934 --> 01:14:09,333
THOMAS: She's proceeding
onto line three
1131
01:14:09,467 --> 01:14:11,767
and we're actually
gonna jump up to that line,
1132
01:14:11,900 --> 01:14:14,100
find a nice comfortable
spot in these floes
1133
01:14:14,233 --> 01:14:15,667
and wait for her there.
1134
01:14:15,800 --> 01:14:19,233
FISHBURNE: For now, AUV
team leader Channing Thomas
1135
01:14:19,367 --> 01:14:23,400
and his team can only follow
their sub's programmed route.
1136
01:14:29,467 --> 01:14:30,600
-(RADIO BEEPS)
-Roger.
1137
01:14:31,633 --> 01:14:34,066
We monitor it
still on that line
1138
01:14:34,200 --> 01:14:37,567
as long as we can
to make sure she's flying true
1139
01:14:37,700 --> 01:14:40,834
and straight
and at the right altitude.
1140
01:14:40,967 --> 01:14:43,166
FISHBURNE:
Much like on an airplane,
1141
01:14:43,300 --> 01:14:45,533
all the scan data
from the AUV sub
1142
01:14:45,667 --> 01:14:49,867
is recorded onto a black box
stored on the sub itself.
1143
01:14:51,433 --> 01:14:54,100
Devon will only find out
if it's found the wreck
1144
01:14:54,233 --> 01:14:57,166
once they pull it out
of the water.
1145
01:14:57,300 --> 01:14:59,734
But that won't be
for another 24 hours.
1146
01:15:07,500 --> 01:15:09,834
Five months
after losing his ship,
1147
01:15:09,967 --> 01:15:13,567
Shackleton faced
impossible odds in Antarctica.
1148
01:15:13,700 --> 01:15:17,166
He left 22 men behind
on Elephant Island
1149
01:15:17,300 --> 01:15:22,000
and he's braving the worst
ocean on the planet.
1150
01:15:22,133 --> 01:15:25,800
But after battling across
800 miles of it in two weeks
1151
01:15:25,934 --> 01:15:28,900
and painfully dehydrated,
1152
01:15:29,033 --> 01:15:32,300
he finally spots the island
of South Georgia.
1153
01:15:32,433 --> 01:15:34,700
They'd made it.
They had made
1154
01:15:34,834 --> 01:15:36,834
the toughest
crossing in the world
1155
01:15:36,967 --> 01:15:41,233
in a vessel that never made
that crossing before.
1156
01:15:41,367 --> 01:15:43,400
There was a sense of euphoria.
1157
01:15:46,834 --> 01:15:49,700
FISHBURNE: From his landing
point at King Haakon Bay,
1158
01:15:49,834 --> 01:15:52,300
the closest settlement
is a whaling station,
1159
01:15:52,433 --> 01:15:54,266
30 miles to the east.
1160
01:15:56,367 --> 01:16:00,567
But blocking his path now
is a towering mountain range.
1161
01:16:03,033 --> 01:16:06,166
LARSON: The mountains
were covered with snow and ice
1162
01:16:06,300 --> 01:16:09,300
and to get some sort of
traction on the snow,
1163
01:16:09,433 --> 01:16:13,233
they took nails out of the boat
1164
01:16:13,367 --> 01:16:16,367
and pounded them through
the bottom of the shoe.
1165
01:16:16,500 --> 01:16:18,700
FISHBURNE:
Mountaineer Conrad Anker
1166
01:16:18,834 --> 01:16:20,867
has followed
Shackleton's route.
1167
01:16:21,000 --> 01:16:24,066
ANKER: Shackleton's
traverse of South Georgia,
1168
01:16:24,200 --> 01:16:26,300
in the context
of when he did it,
1169
01:16:26,433 --> 01:16:29,934
was certainly one of
the most technical climbs
1170
01:16:30,066 --> 01:16:31,233
done in the mountains.
1171
01:16:32,667 --> 01:16:36,433
If they didn't make it,
their men were going to die.
1172
01:16:36,567 --> 01:16:39,700
And when you have that degree
of immediacy on your goals,
1173
01:16:40,567 --> 01:16:41,734
you get things done.
1174
01:16:43,600 --> 01:16:46,266
FISHBURNE: After climbing
for 36 hours,
1175
01:16:48,934 --> 01:16:52,367
Shackleton finally limps
into civilization.
1176
01:16:58,033 --> 01:17:00,767
LARSON: When Shackleton told
his story of what they'd
1177
01:17:00,900 --> 01:17:03,433
been through, no-one
at the whaling station,
1178
01:17:03,567 --> 01:17:05,033
they couldn't believe it.
1179
01:17:05,166 --> 01:17:08,767
Every step of this story
was beyond belief.
1180
01:17:12,266 --> 01:17:15,500
But, of course, it wasn't over
for Shackleton then.
1181
01:17:15,633 --> 01:17:18,500
He had to go back and save
the people on Elephant Island.
1182
01:17:18,633 --> 01:17:22,667
FISHBURNE: Shackleton strives
tirelessly for four months,
1183
01:17:22,800 --> 01:17:25,433
to break back
through the frozen sea.
1184
01:17:28,400 --> 01:17:31,300
At last,
he approaches Elephant Island.
1185
01:17:32,767 --> 01:17:34,767
And as he's going ashore,
the men on the island
1186
01:17:34,900 --> 01:17:37,433
are seeing the rescue boat
is here
1187
01:17:37,567 --> 01:17:39,867
and they're starting to come
out from under the shelter.
1188
01:17:40,000 --> 01:17:42,967
And Shackleton is counting,
"One, two, three, four,"
1189
01:17:43,100 --> 01:17:46,066
all the way up until
he's counted everyone.
1190
01:17:52,100 --> 01:17:54,934
And he looks to Worsley
and says,
1191
01:17:55,066 --> 01:17:57,166
"They're all there,
they're all alive."
1192
01:17:57,300 --> 01:18:00,467
And the emotion
that he had at that time,
1193
01:18:00,600 --> 01:18:02,066
had to be just overwhelming.
1194
01:18:07,633 --> 01:18:12,000
LOVELL: To bring everybody on
his expedition back home alive,
1195
01:18:12,133 --> 01:18:15,767
was probably one of the
greatest adventure achievements
1196
01:18:15,900 --> 01:18:18,166
that we have
in our history books.
1197
01:18:22,066 --> 01:18:23,834
FISHBURNE: On board
the Agulhas II,
1198
01:18:23,967 --> 01:18:25,967
the crew hunting down
Shackleton's wreck
1199
01:18:26,100 --> 01:18:27,900
has suffered a major blow.
1200
01:18:32,333 --> 01:18:34,333
Thirty hours into the dive,
1201
01:18:34,467 --> 01:18:38,433
the AUV that's scanning
the seafloor has gone missing.
1202
01:18:40,333 --> 01:18:42,000
The multi-million-dollar
machine
1203
01:18:42,133 --> 01:18:43,367
has likely located
the wreck.
1204
01:18:45,667 --> 01:18:47,900
But AUV operators
Devon and Blake
1205
01:18:48,033 --> 01:18:49,767
have lost contact with it.
1206
01:18:50,967 --> 01:18:52,834
If they can't reconnect,
1207
01:18:52,967 --> 01:18:54,633
they'll never find out
what's below.
1208
01:18:54,767 --> 01:18:57,100
We've gotten over the site.
1209
01:18:57,233 --> 01:19:01,266
We've got the best equipment
and opportunity to find it
1210
01:19:01,400 --> 01:19:03,033
and if we can't recover
the data
1211
01:19:03,166 --> 01:19:04,567
after the AUV has already run
its mission,
1212
01:19:04,700 --> 01:19:06,500
that's kind of heart-breaking.
1213
01:19:09,400 --> 01:19:12,367
FISHBURNE: Devon's last
hope is that it's waiting
1214
01:19:12,500 --> 01:19:15,033
at its rendezvous point,
ten miles away,
1215
01:19:15,166 --> 01:19:17,934
600 feet below the surface.
1216
01:19:18,066 --> 01:19:20,967
But they need
to get there fast.
1217
01:19:21,100 --> 01:19:24,200
The AUV's battery
is running down
1218
01:19:24,333 --> 01:19:27,500
and once the battery dies,
the AUV's nothing more
1219
01:19:27,633 --> 01:19:30,233
than a 4,000-pound paperweight.
1220
01:19:33,233 --> 01:19:34,667
The problem is,
1221
01:19:34,800 --> 01:19:37,433
getting anywhere out
here is far from easy.
1222
01:19:39,266 --> 01:19:41,066
Twelve hours into the chase,
1223
01:19:42,333 --> 01:19:45,800
the Agulhas II grinds
to a halt.
1224
01:19:45,934 --> 01:19:47,533
(JUDDERING)
1225
01:19:52,533 --> 01:19:54,367
BOUND: We're stuck.
1226
01:19:56,433 --> 01:19:58,600
In normal conditions
with open water,
1227
01:19:58,734 --> 01:20:01,333
we'd just shoot over
to the loiter box,
1228
01:20:01,467 --> 01:20:03,533
pick her up
and everything would be fine.
1229
01:20:03,667 --> 01:20:07,300
But, yeah,
right now we can't move.
1230
01:20:07,433 --> 01:20:11,433
We're now almost eight nautical
miles to get to the spot
1231
01:20:11,567 --> 01:20:13,400
and her battery is running out.
1232
01:20:15,533 --> 01:20:18,433
It's tough to search for an AUV
in this kind of situation.
1233
01:20:20,100 --> 01:20:22,400
FISHBURNE: The team
doesn't have time to wait.
1234
01:20:22,533 --> 01:20:26,133
Last time the ship got stuck,
it took 14 hours to escape.
1235
01:20:27,166 --> 01:20:29,233
If it takes that long again,
1236
01:20:29,367 --> 01:20:32,200
the sub's battery will be dead
before they reach it.
1237
01:20:33,467 --> 01:20:35,133
It's just a waiting game.
1238
01:20:35,266 --> 01:20:37,200
It depends on how long we got,
we need to wait,
1239
01:20:37,333 --> 01:20:39,333
so, hopefully,
not too much longer
1240
01:20:39,467 --> 01:20:41,000
because we are losing time.
1241
01:20:48,033 --> 01:20:49,800
(CRACKING)
1242
01:20:55,567 --> 01:20:59,300
FISHBURNE: At last,
the ship breaks free.
1243
01:21:06,667 --> 01:21:08,066
By the time the Agulhas II
1244
01:21:08,200 --> 01:21:10,934
makes it to
the planned end point,
1245
01:21:11,066 --> 01:21:14,333
the AUV's only got
four hours of battery left.
1246
01:21:16,400 --> 01:21:19,600
The team prepares to lower
its main communication system.
1247
01:21:21,066 --> 01:21:22,867
Yeah, we're just gonna
get it together here,
1248
01:21:23,000 --> 01:21:25,066
spin it and then lift it.
1249
01:21:32,400 --> 01:21:34,767
FISHBURNE:
But there's no signal.
1250
01:21:36,300 --> 01:21:38,300
The AUV is not where
they hoped.
1251
01:21:41,066 --> 01:21:43,400
There's just
one last possibility.
1252
01:21:45,233 --> 01:21:48,066
Has it come up
and gotten stuck under the ice?
1253
01:21:50,100 --> 01:21:52,433
Devon and Blake
want to use another device
1254
01:21:52,567 --> 01:21:54,934
to boost the comms system.
1255
01:21:55,066 --> 01:21:59,934
We're gonna drop this
transponder down into the water
1256
01:22:00,133 --> 01:22:03,767
and bounce the signal
possibly to the AUV.
1257
01:22:07,667 --> 01:22:10,800
At this point,
any response is good.
1258
01:22:10,934 --> 01:22:13,033
FISHBURNE: They need to pick up
a signal from the sub.
1259
01:22:13,166 --> 01:22:16,233
This is the last known
possible location.
1260
01:22:18,266 --> 01:22:20,467
-I'm 50/50.
-Yep.
1261
01:22:20,600 --> 01:22:22,800
It's a crap shoot.
1262
01:22:22,934 --> 01:22:25,400
FISHBURNE: It's the team's
final roll of the dice.
1263
01:22:27,667 --> 01:22:29,233
But what will they find?
1264
01:22:46,300 --> 01:22:48,433
FISHBURNE: At the site
where Ernest Shackleton
1265
01:22:48,567 --> 01:22:51,433
lost his ship a century ago
1266
01:22:51,567 --> 01:22:52,967
the team sent to find it
1267
01:22:53,100 --> 01:22:54,800
has a tough call to make.
1268
01:22:57,767 --> 01:22:59,700
Their final attempt to locate
1269
01:22:59,834 --> 01:23:03,867
their multi-million-dollar
AUV sub has failed.
1270
01:23:05,867 --> 01:23:08,934
We got there and we could
not establish communication
1271
01:23:09,066 --> 01:23:12,100
and we started realizing
it's not here.
1272
01:23:12,233 --> 01:23:16,200
FISHBURNE: Without the AUV,
the hunt for the wreck is over.
1273
01:23:18,734 --> 01:23:20,333
It hurt. You know?
1274
01:23:28,700 --> 01:23:31,200
FISHBURNE: The AUV
could be anywhere.
1275
01:23:31,333 --> 01:23:33,133
It's likely out of battery.
1276
01:23:35,800 --> 01:23:37,834
And temperatures
are dropping fast.
1277
01:23:39,767 --> 01:23:42,967
The ice floes that have trapped
them twice in the last 48 hours
1278
01:23:43,100 --> 01:23:44,533
are closing in.
1279
01:23:46,800 --> 01:23:48,667
If they don't get out soon,
1280
01:23:48,800 --> 01:23:51,200
the ice could trap them
for weeks,
1281
01:23:51,333 --> 01:23:53,100
just like the Endurance.
1282
01:23:57,266 --> 01:23:59,734
Captain Bengu makes the call.
1283
01:24:02,367 --> 01:24:04,200
I personally feel we've...
1284
01:24:04,333 --> 01:24:06,066
We've done exceptionally well
1285
01:24:06,200 --> 01:24:07,900
under the circumstances.
1286
01:24:08,033 --> 01:24:10,133
I think we just accept
and let go.
1287
01:24:10,266 --> 01:24:12,066
We are at the end
of the season now.
1288
01:24:12,200 --> 01:24:14,033
This is where the ice
starts forming first
1289
01:24:14,166 --> 01:24:17,166
and, yeah, we should
certainly get out of this area.
1290
01:24:19,000 --> 01:24:20,567
THOMAS: Antarctica's
a tough cookie to crack.
1291
01:24:20,700 --> 01:24:21,967
Shackleton figured that out.
1292
01:24:22,100 --> 01:24:23,333
Obviously we're figuring it out.
1293
01:24:27,333 --> 01:24:29,600
FISHBURNE: The Antarctic
has already cost the team
1294
01:24:29,734 --> 01:24:31,633
one of their AUV subs
1295
01:24:31,767 --> 01:24:34,266
and destroyed
their underwater robot.
1296
01:24:36,967 --> 01:24:40,834
SAINT AMOUR: We came down
with bigger, better technology,
1297
01:24:40,967 --> 01:24:43,166
but the same rules
that Shackleton was playing by,
1298
01:24:43,300 --> 01:24:45,100
still apply today.
1299
01:24:48,600 --> 01:24:50,567
You know, Mother Nature,
at some point
1300
01:24:50,700 --> 01:24:52,800
puts her foot down
and lets you know who's boss.
1301
01:24:55,767 --> 01:24:57,033
ANKER: The ice still rules.
1302
01:24:58,367 --> 01:25:01,734
The ice is still the king
and you have no choice.
1303
01:25:01,867 --> 01:25:05,300
You're merely there
trying to do the best you can.
1304
01:25:05,433 --> 01:25:08,300
FISHBURNE: For now, the secret
of Shackleton's lost ship
1305
01:25:08,433 --> 01:25:12,767
remains locked in the AUV,
hidden beneath the ice.
1306
01:25:12,900 --> 01:25:14,834
JAMES: The AUV
could be anywhere.
1307
01:25:14,967 --> 01:25:17,734
At this point
it's likely that it's buoyant
1308
01:25:17,867 --> 01:25:20,600
and floating under the ice.
1309
01:25:20,734 --> 01:25:22,767
That information
that's on that AUV,
1310
01:25:22,900 --> 01:25:25,333
could hold the secret
of the Endurance.
1311
01:25:29,033 --> 01:25:30,867
We were always
up against the ice.
1312
01:25:31,000 --> 01:25:32,633
That was always
the enemy for us,
1313
01:25:32,767 --> 01:25:34,233
just as it was for Shackleton.
1314
01:25:35,300 --> 01:25:38,166
And, yeah,
it's beaten us also.
1315
01:25:44,400 --> 01:25:47,767
FISHBURNE: The loss of
the Endurance a century ago,
1316
01:25:47,900 --> 01:25:51,033
turned Shackleton
into a legend.
1317
01:25:51,166 --> 01:25:54,500
Shackleton resonates today
1318
01:25:54,633 --> 01:25:58,133
because of keeping
his men together,
1319
01:25:58,266 --> 01:26:01,867
keeping morale up,
doing the impossible
1320
01:26:02,000 --> 01:26:03,834
and then saving them.
1321
01:26:03,967 --> 01:26:05,400
That's Endurance.
1322
01:26:07,667 --> 01:26:11,066
Whenever I'm out there
in a tricky situation,
1323
01:26:11,200 --> 01:26:15,467
climbing or where things
might not be going my way,
1324
01:26:15,600 --> 01:26:19,166
I take a bit of Shackleton
and I plug it in and I'm, like,
1325
01:26:19,300 --> 01:26:22,533
"Yeah, Sir Ernest Shackleton,
1326
01:26:23,900 --> 01:26:26,867
"he would persevere."
1327
01:26:27,000 --> 01:26:30,734
And that is the power
of Shackleton's story.
1328
01:26:35,967 --> 01:26:38,133
FISHBURNE: On the hunt
for Shackleton's wreck,
1329
01:26:38,266 --> 01:26:40,367
the crew has battled
the same conditions
1330
01:26:40,500 --> 01:26:42,700
faced by the Endurance,
1331
01:26:42,834 --> 01:26:45,200
broken through
to one of the most
1332
01:26:45,333 --> 01:26:47,400
remote places
on the planet,
1333
01:26:47,533 --> 01:26:50,000
and explored
for the first time,
1334
01:26:50,133 --> 01:26:53,934
the ship's final resting
ground on the sea floor.
1335
01:26:58,133 --> 01:27:00,767
For the expedition,
getting this close to the wreck
1336
01:27:00,900 --> 01:27:04,500
is a major feat of exploration.
1337
01:27:04,633 --> 01:27:08,133
And while the onset of winter
marks the end of this season,
1338
01:27:08,266 --> 01:27:11,033
the team plans to return.
1339
01:27:11,166 --> 01:27:12,934
If there's an opportunity
to come back
1340
01:27:13,066 --> 01:27:15,600
and search for it again,
I'm gonna be first on the list.
1341
01:27:17,333 --> 01:27:18,834
BONIN: Hopefully
we'll find the AUV
1342
01:27:18,967 --> 01:27:21,066
and Shackleton's ship
in the same spot.
1343
01:27:22,734 --> 01:27:25,834
I always said this was
the greatest wreck hunt
1344
01:27:25,967 --> 01:27:29,000
that there's ever been
and still is.
1345
01:27:29,133 --> 01:27:31,900
I mean, somewhere beneath
my feet is the Endurance.
1346
01:27:32,033 --> 01:27:33,467
And do you know what?
1347
01:27:34,066 --> 01:27:35,734
It isn't over yet.
1348
01:27:37,867 --> 01:27:39,967
SCOTT SHACKLETON: They're
talking about going back
1349
01:27:40,100 --> 01:27:42,800
to the moon, so why not
go back to the Weddell Sea?
1350
01:27:43,800 --> 01:27:46,166
To be able to go down
and find it and locate it
1351
01:27:46,300 --> 01:27:47,867
and document it,
1352
01:27:48,000 --> 01:27:51,367
would be a closure for
this whole Endurance story.
