1
00:00:03,975 --> 00:00:08,305
It's the greatest aviation mystery
of all time*
2
00:00:08,305 --> 00:00:13,384
RADIO CHATTER
3
00:00:13,384 --> 00:00:18,955
How can a Boeing ****
with 2** people on board*
4
00:00:18,955 --> 00:00:21,775
simply vanish without a trace?
5
00:00:26,334 --> 00:00:30,465
The answer lies somewhere at the
bottom of the I ndian Ocean*
6
00:00:33,434 --> 00:00:36,395
I magine if we could empty the
oceans*
7
00:00:36,395 --> 00:00:38,965
letting the water drain away*
8
00:00:38,965 --> 00:00:41,364
to reveal the secrets of the sea
floor*
9
00:00:42,555 --> 00:00:44,364
Now we can
10
00:00:48,085 --> 00:00:51,395
Using the latest underwater scanning
technology
11
00:00:51,395 --> 00:00:56,475
piercing the deep oceans and turning
accurate data into D images
12
00:00:58,525 --> 00:01:00,555
This time
13
00:01:00,555 --> 00:01:03,725
with unique access to the official
investigation
14
00:01:03,725 --> 00:01:06,655
key mysteries of Malaysia Airlines
0
15
00:01:08,515 --> 00:01:12,194
What lessons lie amid the wrecks of
previous air disasters?
16
00:01:15,005 --> 00:01:18,965
Can Cold War technology extract
vital clues from the deep ocean?
17
00:01:25,464 --> 00:01:27,675
And if the plane is found
18
00:01:27,675 --> 00:01:31,425
what secrets could lie hidden in the
tangled wreckage?
19
00:02:05,025 --> 00:02:07,565
March 8th 201
20
00:02:07,565 --> 00:02:11,415
Malaysia Airlines Flight 0 departs
uala Lumpur
21
00:02:11,415 --> 00:02:13,835
on a six- hour to Beijing
22
00:02:23,505 --> 00:02:28,105
As the Boeing enters Vietnamese
airspace
23
00:02:28,105 --> 00:02:30,785
it suddenly drops off air traffic
control radar
24
00:02:38,905 --> 00:02:41,224
A modern commercial airliner
25
00:02:41,224 --> 00:02:45,464
carrying 2 people has just
vanished
26
00:02:49,214 --> 00:02:51,705
There's no Mayday call
27
00:02:51,705 --> 00:02:54,835
and no wreckage at the point of last
radar contact
28
00:03:06,134 --> 00:03:09,464
Aviation authorities struggle to
understand
29
00:03:09,464 --> 00:03:12,835
We beleve famly members should
prepare themselves for the worst.
30
00:03:16,805 --> 00:03:19,635
Families left behind demand answers
31
00:03:25,045 --> 00:03:28,755
The Malaysian government launches an
investigation
32
00:03:28,755 --> 00:03:32,394
It will be the largest and most
expensive in aviation history
33
00:03:34,555 --> 00:03:36,705
With multiple dead ends
34
00:03:36,705 --> 00:03:38,344
false leads
35
00:03:38,344 --> 00:03:40,695
a deluge of speculation
36
00:03:40,695 --> 00:03:42,855
but only a handful of real clues
37
00:03:45,464 --> 00:03:48,535
One of the first comes from the
Malaysia military
38
00:03:51,224 --> 00:03:54,264
Powerful defence radar has detected
the plane
39
00:03:54,264 --> 00:03:57,214
turning back across Malaysia
40
00:03:57,214 --> 00:04:00,475
heading north-west up the Straight
of Malacca
41
00:04:00,475 --> 00:04:04,685
then disappearing out of range here
just north of Sumatra
42
00:04:06,535 --> 00:04:08,095
It's a shocking discovery
43
00:04:09,605 --> 00:04:12,845
After it disappeared from civilian
radar
44
00:04:12,845 --> 00:04:14,675
it didn't crash
45
00:04:14,675 --> 00:04:16,204
it continued flying
46
00:04:17,485 --> 00:04:20,535
I ntally when the aeroplane made a
turn
47
00:04:20,535 --> 00:04:23,124
wthout talkng to ar traffc
control
48
00:04:23,124 --> 00:04:24,755
n my mnd all bets were off.
49
00:04:26,395 --> 00:04:29,994
It could be a terrorst event
t could be a delberate act
50
00:04:29,994 --> 00:04:33,735
by a crewmember t could be a mass
falure n the electrcal system.
51
00:04:38,735 --> 00:04:40,835
The next clue comes from space
52
00:04:43,405 --> 00:04:45,124
Although lost to radar
53
00:04:45,124 --> 00:04:50,014
MH0 continued to exchange what are
called heartbeat signals
54
00:04:50,014 --> 00:04:53,185
with an I nmarsat satellite above the
I ndian Ocean
55
00:04:55,355 --> 00:04:57,105
The heartbeats come once an hour
56
00:04:59,405 --> 00:05:01,765
Frequency changes in the signals
57
00:05:01,765 --> 00:05:05,444
help experts calculate its direction
of travel
58
00:05:05,444 --> 00:05:08,085
and reveal something extraordinary
59
00:05:09,324 --> 00:05:12,295
After its initial track to the
north-west
60
00:05:12,295 --> 00:05:17,124
MH0 turned south and flew for six
more hours
61
00:05:19,285 --> 00:05:21,355
From the travel time of each signal,
62
00:05:21,355 --> 00:05:25,615
investigators also calculate the
plane's distance from the satellite
63
00:05:25,615 --> 00:05:27,485
These lines are called arcs
64
00:05:29,405 --> 00:05:31,915
Using the fuel load and cruising
speed
65
00:05:31,915 --> 00:05:35,115
they can recreate a range of
possible flight paths
66
00:05:35,115 --> 00:05:37,385
as the plane crosses each arc
67
00:05:39,115 --> 00:05:44,264
The final, or seventh arc
is deep in the I ndian Ocean
68
00:05:44,264 --> 00:05:48,344
There are no more heartbeat signals
beyond this point
69
00:05:48,344 --> 00:05:50,905
70
00:05:50,905 --> 00:05:54,595
71
00:05:54,595 --> 00:05:57,305
72
00:05:58,585 --> 00:06:00,474
It's the biggest breakthrough so
far
73
00:06:02,195 --> 00:06:05,865
instantly shifting the search
000 miles south
74
00:06:05,865 --> 00:06:08,024
of the last military radar
contact
75
00:06:10,635 --> 00:06:14,865
taking it into the jurisdiction of
the Australian government
76
00:06:14,865 --> 00:06:18,024
and accident investigator Peter
Foley
77
00:06:18,024 --> 00:06:19,855
78
00:06:19,855 --> 00:06:25,835
79
00:06:25,835 --> 00:06:28,474
80
00:06:28,474 --> 00:06:30,965
81
00:06:30,965 --> 00:06:33,334
82
00:06:36,254 --> 00:06:39,134
They start looking here
83
00:06:39,134 --> 00:06:42,484
a swathe of ocean running 00 miles
along the seventh arc
84
00:06:45,024 --> 00:06:49,745
They estimate that the plane could
lie 10 miles either side
85
00:06:49,745 --> 00:06:52,665
the maximum glide range of a
86
00:06:59,425 --> 00:07:03,435
The seventh arc is over 1500 miles
from the nearest land
87
00:07:06,144 --> 00:07:09,354
It will take two days for Australian
search vessels to get there
88
00:07:11,144 --> 00:07:15,925
Two powerful storms have swept
through since MH0 disappeared
89
00:07:15,925 --> 00:07:18,805
making the job of spotting debris
even harder
90
00:07:20,655 --> 00:07:25,775
22 aircraft and 1 surface vessels
look for wreckage
91
00:07:25,775 --> 00:07:27,264
and possibly even survivors
92
00:07:29,124 --> 00:07:31,845
93
00:07:31,845 --> 00:07:34,565
94
00:07:34,565 --> 00:07:38,815
95
00:07:38,815 --> 00:07:41,645
96
00:07:43,185 --> 00:07:48,445
Surface debris is normally the first
step to finding a missing aircraft
97
00:07:48,445 --> 00:07:50,365
but it is not a guarantee
98
00:07:50,365 --> 00:07:55,655
Before MH0 the largest and most
expensive search in aviation history
99
00:07:55,655 --> 00:07:59,445
takes place here 8000 miles away
in the Atlantic Ocean
100
00:08:03,084 --> 00:08:06,285
Hunting for the wreck of Air France
Flight
101
00:08:08,535 --> 00:08:11,615
What lessons lie amid this tangled
wreckage
102
00:08:11,615 --> 00:08:13,735
for those searching for MH0?
103
00:08:21,175 --> 00:08:23,665
On J une 1st 200
104
00:08:23,665 --> 00:08:27,665
Air France Flight leaves Rio de
Janeiro Brazil,
105
00:08:27,665 --> 00:08:31,835
carrying 21 passengers and 12 crew
to Paris
106
00:08:35,515 --> 00:08:39,274
Weather reports indicate severe
thunderstorms along the flight path
107
00:08:41,715 --> 00:08:44,305
Three hours and 5 minutes into the
flight
108
00:08:44,305 --> 00:08:46,635
as the plane nears the equator
109
00:08:46,635 --> 00:08:49,705
its onboard computers send a
burst of emergency warnings
110
00:08:51,114 --> 00:08:53,085
then fall silent
111
00:08:58,985 --> 00:09:02,185
Olivier Ferrante is in charge of the
French search team
112
00:09:04,395 --> 00:09:07,875
The warning signals are his first
clue
113
00:09:07,875 --> 00:09:11,034
o mantenance messages and an
mportant poston message
114
00:09:11,034 --> 00:09:14,085
whch was very useful for a search.
115
00:09:15,675 --> 00:09:18,975
It is a deep and remote stretch of
ocean
116
00:09:18,975 --> 00:09:21,264
but the search team has every
advantage
117
00:09:22,295 --> 00:09:24,805
A known flight path
118
00:09:24,805 --> 00:09:27,295
an accurate final position
119
00:09:27,295 --> 00:09:31,264
and then surface debris -
found within five days
120
00:09:33,805 --> 00:09:36,645
And yet despite initial optimism
121
00:09:36,645 --> 00:09:40,955
it takes two years
four expeditions
122
00:09:40,955 --> 00:09:43,795
and 0 million to find the plane
123
00:09:45,075 --> 00:09:49,305
Yes I remember that moment when we
found the wreckage.
124
00:09:49,305 --> 00:09:54,745
I was very careful because weve
had false alerts before
125
00:09:54,745 --> 00:09:57,515
and then t turned out to be
geology
126
00:09:57,515 --> 00:09:59,435
or not what we were lookng for.
127
00:10:01,305 --> 00:10:03,185
Why does it take so long?
128
00:10:04,825 --> 00:10:08,395
Using the data meticulously
collected by the search team
129
00:10:08,395 --> 00:10:11,955
combined with the latest
visualisation technology
130
00:10:11,955 --> 00:10:15,875
it is possible to drain the Atlantic
Ocean
131
00:10:15,875 --> 00:10:20,274
revealing the hostile world that
faces every deep-water search effort
132
00:10:22,435 --> 00:10:24,595
I mmense water pressure
133
00:10:24,595 --> 00:10:27,755
freezing cold total darkness
134
00:10:27,755 --> 00:10:29,595
and hidden dangers everywhere
135
00:10:31,647 --> 00:10:35,506
Finally at 12800ft
136
00:10:35,506 --> 00:10:38,936
the shattered remains of Air France
Flight
137
00:10:41,176 --> 00:10:43,376
Engines
138
00:10:43,376 --> 00:10:47,576
wheel assemblies and other heavy
items lie together
139
00:10:49,296 --> 00:10:53,946
The twisted remains a testament
to the force of the impact
140
00:10:56,796 --> 00:10:59,466
Smaller lighter objects stretch
along more than
141
00:10:59,466 --> 00:11:01,895
a third of a mile of sea floor
142
00:11:01,895 --> 00:11:04,816
equivalent to ten New York City
blocks
143
00:11:06,225 --> 00:11:08,866
And a critical realisation
144
00:11:08,866 --> 00:11:13,596
the sea bed wreckage is nowhere near
the surface wreckage
145
00:11:13,596 --> 00:11:16,256
It's almost 2 miles away
146
00:11:17,746 --> 00:11:20,666
I nvestigators spend about two years
147
00:11:20,666 --> 00:11:23,946
searching in this very
challenging area
148
00:11:23,946 --> 00:11:25,866
not realising that ocean currents
149
00:11:25,866 --> 00:11:28,316
have carried debris far from the
crash site
150
00:11:32,025 --> 00:11:34,025
The long and frustrating search for
151
00:11:34,025 --> 00:11:37,355
the French aircraft carries a
warning
152
00:11:37,355 --> 00:11:41,225
Even with debris and an accurate
final position
153
00:11:41,225 --> 00:11:45,386
when a plane goes into deep water
it's very hard to find
154
00:11:48,716 --> 00:11:52,466
A sobering thought for the team
searching for MH0
155
00:11:53,756 --> 00:11:56,466
Ar France was very dffcult
156
00:11:56,466 --> 00:12:00,186
wth our area of 7 square
klometres
157
00:12:00,186 --> 00:12:06,306
but ts nothng compared to the
surface that the search teams
158
00:12:06,306 --> 00:12:11,266
have to search for MH7
ts much more dffcult.
159
00:12:14,035 --> 00:12:16,025
I n the southern I ndian Ocean
160
00:12:16,025 --> 00:12:19,516
investigators look for surface
debris for over two weeks
161
00:12:21,266 --> 00:12:25,035
Even with the aid of satellites
they find nothing
162
00:12:26,105 --> 00:12:28,796
One of the greatest ntal
mysteres
163
00:12:28,796 --> 00:12:34,186
and that has transcended the entre
perod of tme that weve been
164
00:12:34,186 --> 00:12:36,596
lookng for ths aeroplane
wheres the debrs?
165
00:12:40,905 --> 00:12:44,506
With no debris they need to find
another way to narrow the search
166
00:12:48,506 --> 00:12:52,436
So they focus on MH0's black box
data recorders
167
00:12:54,235 --> 00:12:57,946
Each has an underwater locator
beacon or U LB
168
00:12:59,165 --> 00:13:01,716
I n water they emit an electronic
ping
169
00:13:01,716 --> 00:13:03,876
with a range of just over a mile
170
00:13:05,956 --> 00:13:08,826
Find the beacons and you find the
plane
171
00:13:10,035 --> 00:13:12,826
But time is running out
172
00:13:12,826 --> 00:13:16,516
173
00:13:16,516 --> 00:13:20,186
174
00:13:20,186 --> 00:13:23,826
By the time specialist pinger
locator technology reaches the
175
00:13:23,826 --> 00:13:28,155
search zone there are just three
days of battery life left
176
00:13:35,755 --> 00:13:38,676
teer . teer .
177
00:13:38,676 --> 00:13:44,036
I nvestigators have only a few days
to locate MH0's black boxes
178
00:13:44,036 --> 00:13:47,436
before their locator batteries run
out
179
00:13:47,436 --> 00:13:49,486
Faced with a vast search zone
180
00:13:49,486 --> 00:13:53,076
they decide to focus on commonly
used air routes
181
00:13:53,076 --> 00:13:57,596
182
00:13:57,596 --> 00:14:01,356
183
00:14:01,356 --> 00:14:03,486
184
00:14:06,116 --> 00:14:10,825
Australian Navy vessel Ocean Shield
steams to the point where the air
185
00:14:10,825 --> 00:14:13,196
route to Perth intersects the
seventh arc
186
00:14:21,566 --> 00:14:24,356
The team looking for Air France
187
00:14:24,356 --> 00:14:28,515
also use pinger locators in an
attempt to discover the crash site
188
00:14:34,755 --> 00:14:36,705
They begin listening for signals
189
00:14:36,705 --> 00:14:39,715
within days of the plane's
disappearance
190
00:14:39,715 --> 00:14:42,876
I n most cases the pnger locator
works
191
00:14:42,876 --> 00:14:47,606
And that the assumpton before Ar
France **7.
192
00:14:47,606 --> 00:14:51,965
Ships scour the search area for 0
days
193
00:14:51,965 --> 00:14:53,276
but here - nothing
194
00:14:54,786 --> 00:14:56,476
The hunters wonder
195
00:14:56,476 --> 00:14:59,715
are the locator beacons lost
or destroyed?
196
00:15:03,556 --> 00:15:08,116
Returning to the remarkable drained
seascape of the Air France
197
00:15:08,116 --> 00:15:10,796
wreckage reveals the scale of the
problem
198
00:15:12,715 --> 00:15:17,436
The sea floor here is 12800 feet
below the surface
199
00:15:20,046 --> 00:15:21,835
deep in the Mid -Atlantic Ridge
200
00:15:25,036 --> 00:15:27,066
And here amid the wreckage
201
00:15:27,066 --> 00:15:29,595
nestling in the remains of the
tailplane
202
00:15:29,595 --> 00:15:33,765
the black boxes one with its
locator beacon still attached
203
00:15:35,236 --> 00:15:41,226
A search ship passed directly over
here but detected nothing
204
00:15:41,226 --> 00:15:44,556
The metal wreckage may have blocked
the signals
205
00:15:44,556 --> 00:15:49,046
or they could have been damaged by
the sheer force of the impact
206
00:15:49,046 --> 00:15:53,585
I thnk they were unfortunately
damaged at that stage.
207
00:15:58,316 --> 00:16:02,226
I nvestigators listening for the
MH0 black boxes
208
00:16:02,226 --> 00:16:04,416
can only hope they'll have better
luck
209
00:16:06,166 --> 00:16:10,796
They monitor the ocean for 15 days
using three ships equipped
210
00:16:10,796 --> 00:16:13,845
with sensitive listening technology
211
00:16:13,845 --> 00:16:17,116
and military aircraft launching
sonar buoys
212
00:16:18,556 --> 00:16:20,396
They do detect some signals
213
00:16:21,686 --> 00:16:23,956
but conclude it's just random
interference
214
00:16:26,515 --> 00:16:28,076
It's another disappointment
215
00:16:30,926 --> 00:16:33,926
But at this low point
216
00:16:33,926 --> 00:16:35,696
there's a dramatic new lead
217
00:16:39,835 --> 00:16:43,356
A team from Curtin University in
Western Australia
218
00:16:43,356 --> 00:16:46,845
runs a network of sensitive
underwater microphones
219
00:16:46,845 --> 00:16:48,206
called hydrophones
220
00:16:50,796 --> 00:16:53,765
positioned all around the
Australian coast
221
00:16:55,556 --> 00:16:58,126
They're designed to monitor
earthquakes
222
00:16:58,126 --> 00:17:01,396
Antarctic ice and wildlife
223
00:17:01,396 --> 00:17:05,715
And remarkably one of them has
picked up an unusual noise
224
00:17:07,806 --> 00:17:12,286
one hour and 1 minutes after
MH0's last communication
225
00:17:12,286 --> 00:17:14,556
with the I nmarsat satellite
226
00:17:16,566 --> 00:17:19,796
When we looked at the data from that
hydrophone
227
00:17:19,796 --> 00:17:22,696
we found one sgnal that looked as
228
00:17:22,696 --> 00:17:25,057
though t had nterestng
characterstcs.
229
00:17:27,096 --> 00:17:32,406
Is this the actual sound of MH0's
final moments?
230
00:17:32,406 --> 00:17:34,536
U N DERWATER NOISE
231
00:17:39,745 --> 00:17:42,886
Alec Duncan's team look for other
audio recordings
232
00:17:42,886 --> 00:17:45,565
so they can calculate a geographical
fix
233
00:17:47,416 --> 00:17:49,266
One hydrophone does tell you a
234
00:17:49,266 --> 00:17:51,746
certan amount about the source of
the sgnal
235
00:17:51,746 --> 00:17:53,956
so you can tell whether ts a
whale
236
00:17:53,956 --> 00:17:56,366
you can tell whether ts a snappng
shrmp
237
00:17:56,366 --> 00:17:59,026
you can tell whether ts just nose
from the moorng
238
00:17:59,026 --> 00:18:01,156
but you cant tell drecton.
239
00:18:03,946 --> 00:18:08,565
Fortunately other agencies are
listening too
240
00:18:14,126 --> 00:18:16,846
for the sound of illegal nuclear
tests
241
00:18:19,766 --> 00:18:23,926
with technology that can
accurately pinpoint the source
242
00:18:27,176 --> 00:18:30,976
Just off the coast of Cape Lewin
in Western Australia
243
00:18:30,976 --> 00:18:34,296
the Comprehensive Nuclear-Test- Ban
Treaty Organisation
244
00:18:34,296 --> 00:18:36,256
runs a listening post
245
00:18:37,615 --> 00:18:42,256
specifically designed to detect
and locate illegal nuclear tests
246
00:18:44,695 --> 00:18:49,126
The station has three hydrophones
set 125 miles apart
247
00:18:52,815 --> 00:18:58,856
They can determine the direction of
a sound to within half a degree
248
00:18:58,856 --> 00:19:03,216
and calculate the distance to the
source over thousands of miles
249
00:19:06,256 --> 00:19:07,846
And astonishingly
250
00:19:07,846 --> 00:19:11,186
this network has detected the exact
noise
251
00:19:11,186 --> 00:19:13,416
heard by the team from
Curtin University
252
00:19:17,456 --> 00:19:21,815
The analyss of the data from Cape
Lewn told us that
253
00:19:21,815 --> 00:19:25,495
that sgnal had come from the
northwest
254
00:19:25,495 --> 00:19:28,745
and gave us a farly accurate
bearng
255
00:19:28,745 --> 00:19:31,336
along whch the source of that
sgnal must have been.
256
00:19:33,776 --> 00:19:36,096
It's a tantalising clue
257
00:19:36,096 --> 00:19:39,096
and the sound does come from the
direction of the seventh arc
258
00:19:41,186 --> 00:19:43,926
But when the scientists crunch the
numbers
259
00:19:43,926 --> 00:19:47,336
the source of the sound is far to
the north-west
260
00:19:49,176 --> 00:19:51,485
so far beyond the current search
area
261
00:19:51,485 --> 00:19:54,296
that it's considered not worth
further investigation
262
00:19:55,866 --> 00:19:58,695
Our concluson was that the sgnal
was
263
00:19:58,695 --> 00:20:01,825
most lkely to be of geologcal
orgns
264
00:20:01,825 --> 00:20:04,536
such as a small undersea earthquake
265
00:20:04,536 --> 00:20:07,256
but we cant completely rule out the
possblty
266
00:20:07,256 --> 00:20:09,776
that t came from somethng to do
wth the arcraft.
267
00:20:16,296 --> 00:20:18,776
Faced with a new disappointment
268
00:20:18,776 --> 00:20:22,346
the search team moves to a different
approach -
269
00:20:22,346 --> 00:20:24,986
searching the sea floor itself
270
00:20:24,986 --> 00:20:28,466
using towed sleds carrying sonar
scanners
271
00:20:34,066 --> 00:20:38,106
It will be the largest undersea hunt
in history
272
00:20:38,106 --> 00:20:40,615
But before it can even start
there's a new problem
273
00:20:43,815 --> 00:20:47,096
This part of the I ndian Ocean has
never been surveyed in detail
274
00:20:49,495 --> 00:20:51,736
The sleds will be close to the sea
floor
275
00:20:53,406 --> 00:20:55,795
and no-one knows exactly what is
down there
276
00:20:57,495 --> 00:21:00,625
277
00:21:00,625 --> 00:21:04,146
278
00:21:04,146 --> 00:21:07,466
279
00:21:08,625 --> 00:21:13,056
The MH0 team need a simple way to
create a snapshot
280
00:21:13,056 --> 00:21:16,206
of the sea floor across the vast
search area
281
00:21:18,786 --> 00:21:21,266
They find help in an unexpected
place
282
00:21:28,875 --> 00:21:31,376
The team hunting MH0
283
00:21:31,376 --> 00:21:38,456
across 000 square miles of
I ndian Ocean face one big problem
284
00:21:38,456 --> 00:21:41,825
More than * of the sea floor area
n ths regon
285
00:21:41,825 --> 00:21:45,576
has not been covered by shps wth
modern equpment
286
00:21:45,576 --> 00:21:49,216
satellte navgaton mult beam
echo sound.
287
00:21:49,216 --> 00:21:51,925
Geophysicist Walter Smith thinks he
288
00:21:51,925 --> 00:21:55,685
might be able to fill in the blanks
using satellites
289
00:21:59,396 --> 00:22:01,566
The satelltes actually cannot see
the bottom
290
00:22:01,566 --> 00:22:03,805
they're not seeng the ocean floor.
291
00:22:03,805 --> 00:22:05,756
What they're dong s usng radar to
292
00:22:05,756 --> 00:22:08,906
measure varatons n the seas
surface heght.
293
00:22:08,906 --> 00:22:11,346
It's possible thanks to gravity
294
00:22:13,106 --> 00:22:18,116
Mountains on the sea floor create
their own gravitational attraction
295
00:22:18,116 --> 00:22:22,086
surrounding water is drawn towards
the mass
296
00:22:22,086 --> 00:22:26,106
creating measurable changes on the
surface
297
00:22:26,106 --> 00:22:30,755
The smallest ones I can resolve are
a klometre or less n heght
298
00:22:30,755 --> 00:22:33,546
and they move the sea surface about
fve centmetres
299
00:22:33,546 --> 00:22:36,316
and the satellte has no problem
resolvng that.
300
00:22:36,316 --> 00:22:40,226
It doesn't have the resolution to
spot the wreckage of an aircraft
301
00:22:40,226 --> 00:22:44,036
but is enough to help create a
basic map of the sea floor
302
00:22:44,036 --> 00:22:47,825
and identify hazards in the MH0
search zone
303
00:22:50,306 --> 00:22:52,236
What does the data reveal?
304
00:22:53,935 --> 00:22:58,326
Using the exact information gathered
by Walter Smith's team
305
00:22:58,326 --> 00:23:01,475
it's possible to drain away the
I ndian Ocean
306
00:23:01,475 --> 00:23:04,595
to show what the ocean floor
actually looks like
307
00:23:07,756 --> 00:23:09,615
As the water flows away
308
00:23:09,615 --> 00:23:12,815
it exposes a world no human has ever
seen before
309
00:23:14,646 --> 00:23:18,646
Dramatic cliffs more than twice the
height of the Empire State Building
310
00:23:21,326 --> 00:23:26,475
Fault lines plunging almost 20000ft
deeper than any canyon on land
311
00:23:30,526 --> 00:23:34,767
A volcano-dotted valley running for
100 miles
312
00:23:36,516 --> 00:23:39,687
Operating underwater scanning
vehicles in this terrain
313
00:23:39,687 --> 00:23:42,856
will take a huge amount of skill and
luck
314
00:23:49,497 --> 00:23:51,976
Armed with their new map of the sea
floor
315
00:23:51,976 --> 00:23:55,207
the search team deploys the latest
in subsea technology
316
00:23:56,487 --> 00:23:58,331
Travelling deep underwater
317
00:23:58,331 --> 00:24:01,146
these towed sleds begin to scan the
sea floor
318
00:24:03,266 --> 00:24:06,955
and they will be guided by a
game-changing new clue
319
00:24:09,796 --> 00:24:12,236
It comes from further detailed
analysis
320
00:24:12,236 --> 00:24:15,916
of the final I nmarsat signal from
MH0
321
00:24:17,505 --> 00:24:19,986
Engineers crunch the numbers
322
00:24:19,986 --> 00:24:22,466
and discover something shocking
323
00:24:22,466 --> 00:24:26,436
I n its final moments
the plane descends rapidly -
324
00:24:26,436 --> 00:24:29,866
almost certainly because
after 5 hours in the air
325
00:24:29,866 --> 00:24:31,146
it's run out of fuel
326
00:24:33,986 --> 00:24:36,316
Boeing engineers then simulate what
327
00:24:36,316 --> 00:24:40,066
happens when a exhausts its
fuel,
328
00:24:40,066 --> 00:24:42,755
making it possible for the first
time
329
00:24:42,755 --> 00:24:48,316
to recreate the likely final minutes
of MH0's mysterious flight
330
00:24:50,856 --> 00:24:53,266
The right engine flames out first
331
00:24:55,835 --> 00:24:59,956
The autopilot compensates for the
imbalance with a hard left turn
332
00:25:04,705 --> 00:25:07,715
Minutes later the second engine
flames out
333
00:25:10,585 --> 00:25:14,326
With no power the autopilot
switches off
334
00:25:14,326 --> 00:25:18,466
leaving MH0 in a long spiral
descent
335
00:25:47,196 --> 00:25:50,066
I n every Boeing simulation
336
00:25:50,066 --> 00:25:54,226
the crash site lies within 2 miles
of the seventh arc
337
00:25:58,066 --> 00:26:00,266
These dramatic new insights
338
00:26:00,266 --> 00:26:03,426
immediately reduce the size of the
search area
339
00:26:03,426 --> 00:26:08,916
from 000 square miles to just
2000
340
00:26:10,426 --> 00:26:14,625
But that's still three and a half
times the size of the search area
341
00:26:14,625 --> 00:26:17,296
for Air France
342
00:26:17,296 --> 00:26:19,326
Ths s a massve search area
343
00:26:19,326 --> 00:26:23,765
ts magntude s larger than any
prevous search I've ever worked on.
344
00:26:23,765 --> 00:26:26,556
Deep-sea salvage expert Andy
Sherrell
345
00:26:26,556 --> 00:26:30,426
analyses all the data that's been
gathered underwater
346
00:26:30,426 --> 00:26:35,146
Oddly enough when I frst heard
about MH7s dsappearance
347
00:26:35,146 --> 00:26:38,866
my wfe was n labour wth our frst
chld.
348
00:26:38,866 --> 00:26:41,585
The news came on about the
dsappearance of the flght
349
00:26:41,585 --> 00:26:43,546
and my wfe looked at me and she
sad
350
00:26:43,546 --> 00:26:46,575
* Now that's a job you're not gong
to get nvolved wth.*
351
00:26:46,575 --> 00:26:49,556
Andy has been involved ever since
352
00:26:50,755 --> 00:26:54,436
Using his knowledge from six
previous investigations
353
00:26:54,436 --> 00:26:58,276
including a search for Amelia
Earhart's Lockheed Electra
354
00:27:06,266 --> 00:27:09,076
As soon as the underwater scanning
begins
355
00:27:09,076 --> 00:27:12,666
it identifies shapes that could be
man- made
356
00:27:12,666 --> 00:27:15,476
o when you're revewng the sde
scan sonar
357
00:27:15,476 --> 00:27:17,666
t comes down n a waterfall dsplay
358
00:27:17,666 --> 00:27:20,705
and you can see the dfferent
ntenstes of you know
359
00:27:20,705 --> 00:27:23,236
soft sand versus hard rock.
360
00:27:23,236 --> 00:27:24,666
Guided by the scans
361
00:27:24,666 --> 00:27:27,946
the team investigate 80 locations in
detail
362
00:27:30,306 --> 00:27:33,206
but find no trace of MH0
363
00:27:35,236 --> 00:27:41,916
Then in May 2015 the sonar picks
up something new and exciting
364
00:27:41,916 --> 00:27:45,505
It was a typcal lookng debrs
feld
365
00:27:45,505 --> 00:27:48,635
that defntely warranted more
nvestgaton.
366
00:27:52,876 --> 00:27:56,426
The debris field covers an area
similar in size
367
00:27:56,426 --> 00:27:58,946
to the wreckage of Air France
368
00:28:02,755 --> 00:28:06,645
Could this finally be the remains of
MH0?
369
00:28:08,866 --> 00:28:11,635
370
00:28:11,635 --> 00:28:14,156
371
00:28:14,156 --> 00:28:16,396
372
00:28:16,396 --> 00:28:19,996
373
00:28:19,996 --> 00:28:22,595
374
00:28:26,286 --> 00:28:28,926
They launch an autonomous underwater
vehicle
375
00:28:28,926 --> 00:28:32,126
armed with state-of-the-art sensors
to take a closer look
376
00:28:35,595 --> 00:28:38,356
Using the actual data it recorded
that day
377
00:28:38,356 --> 00:28:42,906
it's now possible to drain away the
water from over the site
378
00:28:42,906 --> 00:28:48,595
revealing the most hopeful discovery
so far in the hunt for MH0
379
00:28:50,666 --> 00:28:53,385
At one end a pile of chains
380
00:28:54,585 --> 00:28:59,126
then a 2ft- long metal box
381
00:28:59,126 --> 00:29:01,276
rusted machinery
382
00:29:01,276 --> 00:29:04,086
and finally three metal anchors
383
00:29:06,026 --> 00:29:08,156
They've found a shipwreck
384
00:29:09,566 --> 00:29:12,036
Its wooden hull long rotted away
385
00:29:14,236 --> 00:29:18,996
The site strewn with coal,
probably cargo on its final voyage
386
00:29:20,876 --> 00:29:23,436
They haven't found MH0
387
00:29:23,436 --> 00:29:26,395
but in these dark uncharted
depths
388
00:29:26,395 --> 00:29:29,236
they're casting light on tragedies
from a different age
389
00:29:34,286 --> 00:29:37,796
The investigators discover three
other wrecks
390
00:29:43,116 --> 00:29:48,486
including this iron- hulled sailing
ship upright on the sea bed
391
00:29:54,395 --> 00:29:56,486
And a modern fishing trawler
392
00:29:56,486 --> 00:29:58,725
nets stretched out across the sea
floor
393
00:30:00,956 --> 00:30:03,236
Proving that their technology
394
00:30:03,236 --> 00:30:07,156
can locate and retrieve objects as
small as a piece of coal
395
00:30:11,946 --> 00:30:14,715
After 15 months of detailed
scanning
396
00:30:14,715 --> 00:30:18,635
covering 2000 square miles of sea
floor
397
00:30:18,635 --> 00:30:21,385
there's still no sign of the missing
plane
398
00:30:23,156 --> 00:30:25,076
We have a very hgh confidence that
399
00:30:25,076 --> 00:30:27,876
we would have detected the plane n
that search area
400
00:30:27,876 --> 00:30:31,316
so all these factors gves us
really hgh confidence
401
00:30:31,316 --> 00:30:34,036
that the aeroplane debrs feld s
not n that area.
402
00:30:38,236 --> 00:30:40,226
The investigation continues
403
00:30:40,226 --> 00:30:44,166
still guided by just two key pieces
of evidence -
404
00:30:44,166 --> 00:30:48,156
the I nmarsat calculations and
Boeing's flight performance data
405
00:30:50,725 --> 00:30:52,956
Then suddenly a third line of
inquiry
406
00:30:52,956 --> 00:30:54,515
brings hope of a breakthrough
407
00:30:57,845 --> 00:31:00,796
On a remote island on the other side
of the I ndian Ocean
408
00:31:00,796 --> 00:31:04,385
000 miles from the search area
409
00:31:04,385 --> 00:31:07,635
a piece of metal washes up on a
beach
410
00:31:07,635 --> 00:31:10,366
and it looks like it comes from an
aircraft
411
00:31:16,587 --> 00:31:19,067
I n J uly 2015
412
00:31:19,067 --> 00:31:21,537
a council worker on Reunion island
413
00:31:21,537 --> 00:31:24,046
a French territory in the I ndian
Ocean
414
00:31:24,046 --> 00:31:26,967
stumbles upon an unusual object on a
beach
415
00:31:28,687 --> 00:31:30,457
It's called a flaperon
416
00:31:32,296 --> 00:31:35,327
There is one on each wing of a
Boeing
417
00:31:37,046 --> 00:31:39,457
part of the mechanism that makes
it rise or fall
418
00:31:42,506 --> 00:31:44,527
Boeing quickly confirms that its
419
00:31:44,527 --> 00:31:46,977
serial number matches that of the
missing plane
420
00:31:49,787 --> 00:31:52,657
It's the first piece of physical
evidence
421
00:31:52,657 --> 00:31:55,887
that MH0 ended its flight in the
ocean
422
00:31:57,097 --> 00:32:00,737
It s my hope that ths confrmaton
423
00:32:00,737 --> 00:32:05,506
wll at least brng certanty to the
famles and loved ones.
424
00:32:09,017 --> 00:32:11,657
The suffering of the families
425
00:32:11,657 --> 00:32:15,097
attracts the attention of amateur
wreck hunter Blaine Gibson
426
00:32:16,737 --> 00:32:20,137
and sets him off on a remarkable
personal quest
427
00:32:21,667 --> 00:32:24,376
I was very very touched very
moved
428
00:32:24,376 --> 00:32:29,227
and realsed that I needed to go do
what I could to solve ths.
429
00:32:29,227 --> 00:32:32,667
And what I learned
what that nche was
430
00:32:32,667 --> 00:32:36,657
was that there was no off cal
search
431
00:32:36,657 --> 00:32:39,817
for debrs that washed ashore.
432
00:32:41,737 --> 00:32:46,457
Blaine consults ocean drift experts
who direct him to Mozambique
433
00:32:48,587 --> 00:32:50,506
where he makes an immediate
discovery
434
00:32:53,667 --> 00:32:58,376
And t was a trangular greyshaped
pece of debrs that sad
435
00:32:58,376 --> 00:32:59,767
* No tep* on t.
436
00:32:59,767 --> 00:33:01,126
Clearly arcraft.
437
00:33:05,667 --> 00:33:09,807
I felt an enormous sense of
responsblty...
438
00:33:11,687 --> 00:33:16,747
...because I realsed that I had just
found the second pece of debrs n
439
00:33:16,747 --> 00:33:19,176
the greatest avaton mystery n
hstory.
440
00:33:21,227 --> 00:33:25,697
Boeing confirms that the " No Step"
debris is from MH0
441
00:33:26,777 --> 00:33:32,327
Blaine has found it 50 miles away
from the main search zone
442
00:33:38,897 --> 00:33:42,027
Still acting alone
he continues to search
443
00:33:45,587 --> 00:33:48,617
We just found on Rake beach
444
00:33:48,617 --> 00:33:52,227
ths pece of debrs
we have not pcked t up yet.
445
00:33:54,867 --> 00:34:00,777
Almost 0 pieces of debris thought
to come from MH0 are recovered
446
00:34:00,777 --> 00:34:03,767
all on the western side of the
I ndian Ocean
447
00:34:05,056 --> 00:34:07,867
Blaine Gibson finds 15 of them
448
00:34:09,407 --> 00:34:12,347
One piece stands out from the rest
449
00:34:12,347 --> 00:34:14,777
The most sgnfcant to me
450
00:34:14,777 --> 00:34:17,947
and also to the nvestgaton
451
00:34:17,947 --> 00:34:21,407
was the case around the TV screen on
452
00:34:21,407 --> 00:34:24,617
the back of the seat n front of
you.
453
00:34:24,617 --> 00:34:28,126
Ths s the one that brought tears
to my eyes.
454
00:34:28,126 --> 00:34:32,877
Ths s perhaps the last thng that
somebody saw.
455
00:34:32,877 --> 00:34:37,097
Ths s what anyone who fles on a
plane would recognse.
456
00:34:38,897 --> 00:34:42,697
Debris like this from inside the
passenger cabin
457
00:34:42,697 --> 00:34:46,097
confirms that MH0 hit the water
hard
458
00:34:47,827 --> 00:34:52,947
459
00:34:52,947 --> 00:34:56,697
460
00:34:56,697 --> 00:35:01,457
Another piece of debris helps
resolve a key question
461
00:35:01,457 --> 00:35:05,186
I nvestigators already believe the
plane ran out of fuel
462
00:35:05,186 --> 00:35:07,537
But as it fell towards the ocean
463
00:35:07,537 --> 00:35:10,587
was someone trying to save it with a
controlled ditch?
464
00:35:12,176 --> 00:35:17,777
465
00:35:17,777 --> 00:35:20,627
466
00:35:20,627 --> 00:35:24,136
467
00:35:24,136 --> 00:35:28,376
The flap extends on an internal
support track
468
00:35:28,376 --> 00:35:30,907
I nvestigators discover that the
track has left
469
00:35:30,907 --> 00:35:33,027
impact marks inside the flap
470
00:35:34,487 --> 00:35:38,587
That can only happen if it's
in a retracted position -
471
00:35:38,587 --> 00:35:42,907
strong evidence that the plane was
in its normal cruising state
472
00:35:42,907 --> 00:35:44,547
as it fell towards the sea
473
00:35:48,827 --> 00:35:51,256
474
00:35:51,256 --> 00:35:54,066
475
00:35:54,066 --> 00:35:56,327
476
00:35:56,327 --> 00:36:00,227
477
00:36:00,227 --> 00:36:02,747
478
00:36:06,186 --> 00:36:10,237
The flap supports the theory that
the plane ran out of fuel,
479
00:36:10,237 --> 00:36:12,627
and suggests that no-one at that
point
480
00:36:12,627 --> 00:36:14,386
was trying to ditch or save it
481
00:36:21,497 --> 00:36:26,306
But the debris doesn't only confirm
how MH0 crashed
482
00:36:27,817 --> 00:36:31,617
it opens up a new and exciting
line of inquiry
483
00:36:31,617 --> 00:36:33,747
that could narrow the search area
484
00:36:38,667 --> 00:36:42,306
I thnk ts enormously mportant to
fnd the plane
485
00:36:42,306 --> 00:36:45,547
because whle planes crash
routnely...
486
00:36:46,707 --> 00:36:50,497
...they don't just dsappear and I
thnk ths terrfes people.
487
00:36:52,066 --> 00:36:54,617
Oceanographer David Griffin believes
488
00:36:54,617 --> 00:36:57,056
that the very first piece of debris
recovered
489
00:36:57,056 --> 00:37:01,417
the flaperon on Reunion island
may be the key
490
00:37:01,417 --> 00:37:03,107
Ths could be a good spot I reckon.
491
00:37:03,107 --> 00:37:06,747
The wnds probably a bt stronger
I guess. Yep.
492
00:37:06,747 --> 00:37:11,947
Ths s a Boeng 777 flaperon off
another arcraft not MH7.
493
00:37:11,947 --> 00:37:15,266
Well use ths end to snk t agan
all rght? Yep.
494
00:37:15,266 --> 00:37:18,987
David Griffin is trying to recreate
the journey of the flaperon across
495
00:37:18,987 --> 00:37:23,146
the ocean in the hope this will
pinpoint the crash site
496
00:37:28,936 --> 00:37:32,867
He compares the flaperon's movement
to these buoys
497
00:37:32,867 --> 00:37:35,066
nown as ocean drifters
498
00:37:35,066 --> 00:37:38,467
they're used to daily all around the
world to monitor ocean currents
499
00:37:40,707 --> 00:37:43,396
We very quckly determned that
these replca flaperons
500
00:37:43,396 --> 00:37:48,316
moved about ten centmetres per
second faster downwnd
501
00:37:48,316 --> 00:37:49,917
than an oceanographc drfter.
502
00:37:51,627 --> 00:37:53,827
That may not sound like much
503
00:37:53,827 --> 00:37:56,537
but when he compares it to known
data about the currents
504
00:37:56,537 --> 00:37:59,547
in the seventh arc on the day of the
crash
505
00:37:59,547 --> 00:38:02,027
it helps him estimate the flaperon's
travels
506
00:38:02,027 --> 00:38:04,316
during the 500 days it was afloat
507
00:38:11,217 --> 00:38:13,577
It's an extraordinary discovery
508
00:38:16,987 --> 00:38:19,577
To narrow the search zone even
further
509
00:38:19,577 --> 00:38:22,987
David Griffin investigates another
strange feature of the debris
510
00:38:24,747 --> 00:38:30,037
I n addton to knowng where thngs
are found n Afrca
511
00:38:30,037 --> 00:38:32,787
the other key thng s where thngs
have not been found
512
00:38:32,787 --> 00:38:35,316
and that's Australa.
513
00:38:35,316 --> 00:38:38,926
Why has no debris been washed
ashore in Australia?
514
00:38:40,577 --> 00:38:42,916
Some of the ocean currents in the
search area
515
00:38:42,916 --> 00:38:45,527
flow east towards the country
516
00:38:45,527 --> 00:38:49,376
A plane crashing here should leave
evidence on Australian beaches
517
00:38:51,146 --> 00:38:53,547
o ths mmedately tells us that
518
00:38:53,547 --> 00:38:57,477
all those potental paths of the
seventh arc
519
00:38:57,477 --> 00:39:00,266
where the flow s strongly towards
Australa
520
00:39:00,266 --> 00:39:01,867
they're essentally ruled out.
521
00:39:05,657 --> 00:39:08,266
When David Griffin looks at the
historic drifter data
522
00:39:08,266 --> 00:39:11,577
from the day MH0 disappeared
523
00:39:11,577 --> 00:39:14,196
he finds three places on the seventh
arc
524
00:39:14,196 --> 00:39:16,396
where the current would have pushed
debris
525
00:39:16,396 --> 00:39:18,507
away from Australia towards Africa
526
00:39:20,117 --> 00:39:23,186
Here around * you have ths area
527
00:39:23,186 --> 00:39:26,186
where everythng s movng to the
west.
528
00:39:26,186 --> 00:39:30,217
Agan up at everythngs movng
to the west.
529
00:39:30,217 --> 00:39:32,946
If the plane crashed in one of these
areas
530
00:39:32,946 --> 00:39:37,266
it would explain why debris was not
found in Australia
531
00:39:37,266 --> 00:39:40,907
And critically only one of these
locations
532
00:39:40,907 --> 00:39:43,616
matches his calculation of the
flaperon's journey
533
00:39:45,587 --> 00:39:48,027
o that led us to propose that *
outh
534
00:39:48,027 --> 00:39:50,337
s the most lkely area for the
crash.
535
00:39:54,337 --> 00:39:57,377
5 South is an area that was not
checked
536
00:39:57,377 --> 00:40:00,047
during the initial surface debris
search
537
00:40:02,297 --> 00:40:06,217
For investigators
it's an exciting new lead
538
00:40:06,217 --> 00:40:08,177
but it comes too late
539
00:40:08,177 --> 00:40:09,907
It s wth some level of sadness
540
00:40:09,907 --> 00:40:13,387
certanly wth a great deal of
frustraton and dsappontment
541
00:40:13,387 --> 00:40:16,047
that I stand here and acknowledge
that the search
542
00:40:16,047 --> 00:40:19,577
the underwater search effort
has been suspended.
543
00:40:19,577 --> 00:40:23,297
On January 1th 201
544
00:40:23,297 --> 00:40:26,486
after almost three frustrating
years
545
00:40:26,486 --> 00:40:30,127
the search for MH0 is called off
546
00:40:30,127 --> 00:40:35,097
547
00:40:35,097 --> 00:40:39,327
548
00:40:39,327 --> 00:40:41,377
549
00:40:41,377 --> 00:40:44,577
550
00:40:44,577 --> 00:40:47,817
It was record breakng n terms of
the tme t took
551
00:40:47,817 --> 00:40:50,387
the area that was covered.
552
00:40:50,387 --> 00:40:53,777
Theres never been a search as bg
by an order of magntude.
553
00:40:58,377 --> 00:41:01,666
But will David Griffin's flaperon
experiment
554
00:41:01,666 --> 00:41:05,817
persuade authorities to search 5
degrees south?
555
00:41:08,496 --> 00:41:11,767
It takes almost a year to answer
that question
556
00:41:11,767 --> 00:41:14,847
and new evidence from the skies
557
00:41:25,777 --> 00:41:28,666
Oceanographer David Griffin has a
new theory
558
00:41:30,847 --> 00:41:35,257
He thinks MH0 is in an area called
5 South
559
00:41:37,177 --> 00:41:42,257
And in 201 he finds more evidence
pointing to the same place
560
00:41:43,406 --> 00:41:47,416
I remember the day when I frst saw
those mages n hgh resoluton
561
00:41:47,416 --> 00:41:51,387
and I thought
*My *od ths really helps.*
562
00:41:53,947 --> 00:41:57,536
15 days after MH0 disappeared
563
00:41:57,536 --> 00:42:02,536
a French military satellite captured
images of possible man- made debris
564
00:42:02,536 --> 00:42:04,977
in the vicinity of 5 South
565
00:42:08,656 --> 00:42:12,307
At that time the location wasn't
considered a high priority area
566
00:42:16,736 --> 00:42:20,177
But four years later
it's a different story
567
00:42:20,177 --> 00:42:23,307
And I thought that ths s really
exctng
568
00:42:23,307 --> 00:42:25,697
ths could be used to restart the
search.
569
00:42:30,486 --> 00:42:33,057
A new year brings new hope
570
00:42:33,057 --> 00:42:37,577
I n January 2018 salvage company
Ocean I nfinity
571
00:42:37,577 --> 00:42:40,817
sets out on a brand - new privately
funded mission
572
00:42:43,817 --> 00:42:47,027
The seventh arc is still the focus
573
00:42:47,027 --> 00:42:50,767
but they expand the width of the
previous search zone
574
00:42:50,767 --> 00:42:54,377
and move towards the new area
identified by David Griffin
575
00:42:56,377 --> 00:43:01,387
Once again Andy Sherrell is
on board and this time
576
00:43:01,387 --> 00:43:05,736
he has eight autonomous underwater
vehicles or AUVs
577
00:43:07,507 --> 00:43:12,697
One deep tow vessel would do a swng
of about days onste
578
00:43:12,697 --> 00:43:15,337
and over those days on ste
they'd cover
579
00:43:15,337 --> 00:43:18,257
about * square klometres.
580
00:43:18,257 --> 00:43:20,777
*sng eght A*Vs smultaneously
581
00:43:20,777 --> 00:43:22,947
we can cover that n about three to
four days.
582
00:43:25,746 --> 00:43:27,947
It's a high-stakes gamble
583
00:43:27,947 --> 00:43:30,536
If they find nothing
they don't get paid
584
00:43:34,387 --> 00:43:38,817
Ocean I nfinity searches the new
priority area at 5 South
585
00:43:43,777 --> 00:43:45,257
I n five months
586
00:43:45,257 --> 00:43:48,587
they cover an area almost equal in
size
587
00:43:48,587 --> 00:43:50,687
to the original sea floor search
588
00:43:54,337 --> 00:43:56,736
But frustratingly
589
00:43:56,736 --> 00:43:59,337
they find no trace of MH0
590
00:44:04,057 --> 00:44:06,666
The two search efforts have covered
almost
591
00:44:06,666 --> 00:44:09,937
2000 square miles of sea floor
592
00:44:11,897 --> 00:44:16,097
1 times the size of the Air
France search zone
593
00:44:24,616 --> 00:44:27,097
I n May 2018
594
00:44:27,097 --> 00:44:29,307
the Malaysian government announces
595
00:44:29,307 --> 00:44:31,416
that it will not support any new
searches
596
00:44:32,767 --> 00:44:37,577
597
00:44:39,697 --> 00:44:46,817
Is the wreckage of MH0 waiting to
be discovered in the 8000 square
598
00:44:46,817 --> 00:44:51,507
miles of seventh arc search zone
that remains unexplored?
599
00:44:53,536 --> 00:44:58,247
Do clues to the mystery lie a few
feet outside the circle of light
600
00:44:58,247 --> 00:45:01,017
and knowledge already cast by the
search teams?
601
00:45:02,977 --> 00:45:07,536
Only time money and the continued
desire for answers
602
00:45:07,536 --> 00:45:09,947
separate us from the moment of
discovery
603
00:45:12,777 --> 00:45:17,937
But the knowledge hard -won over two
search efforts and four years
604
00:45:17,937 --> 00:45:20,387
will be invaluable for any future
hunt
605
00:45:24,017 --> 00:45:26,227
Using the extraordinary data
606
00:45:26,227 --> 00:45:28,656
gathered by hundreds of
investigators
607
00:45:28,656 --> 00:45:32,127
we can drain the area around the
seventh arc
608
00:45:32,127 --> 00:45:36,897
to reveal what MH0 might look like
when it is found
609
00:45:40,137 --> 00:45:43,177
The debris will stretch out over
thousands of yards
610
00:45:45,227 --> 00:45:47,587
The engines will be in one piece
611
00:45:47,587 --> 00:45:49,307
the fuselage in thousands
612
00:45:53,027 --> 00:45:55,897
The nearby black boxes will reveal
613
00:45:55,897 --> 00:45:58,027
if anyone was in the cockpit at the
end
614
00:46:01,337 --> 00:46:04,967
Emergency oxygen cylinders may show
if the plane
615
00:46:04,967 --> 00:46:07,057
depressurised in-flight whether
616
00:46:07,057 --> 00:46:09,227
intentionally or the result of an
accident
617
00:46:11,616 --> 00:46:15,507
And personal electronic devices
could reveal the experiences and
618
00:46:15,507 --> 00:46:18,337
fate of individual passengers and
crew
619
00:46:21,267 --> 00:46:23,947
It will be a profound moment
620
00:46:23,947 --> 00:46:27,656
one that Andy Sherrell has
experienced before
621
00:46:27,656 --> 00:46:30,387
Its a really surreal knd of
sombre moment
622
00:46:30,387 --> 00:46:35,107
because you realse all of a sudden
that you've found ths graveste
623
00:46:35,107 --> 00:46:38,777
ths place where all these people
pershed.
624
00:46:38,777 --> 00:46:42,297
Its sad but ts also a bt
of a relef because you know
625
00:46:42,297 --> 00:46:45,866
that from that pont forward some
answers are gong to come back.
626
00:46:45,866 --> 00:46:49,536
I thnk you have to reman
optmstc and f you don't search
627
00:46:49,536 --> 00:46:52,147
you don't fnd so hopefully at the
end they wll fnd t.
628
