Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:02,037 --> 00:00:05,234
A brand-new 767
2
00:00:12,685 --> 00:00:16,210
A catastrophic failure at 26,000 ft
3
00:00:18,562 --> 00:00:20,562
Air Canada 143, go ahead
4
00:00:20,586 --> 00:00:22,132
I just lost both engines
5
00:00:22,156 --> 00:00:23,890
Holy cow!
6
00:00:23,914 --> 00:00:25,914
I am talking to a dead man
7
00:00:35,138 --> 00:00:38,231
The crew is out of options
and running out of time
8
00:00:42,411 --> 00:00:45,918
They are at the controls of a 95 ton jet...
9
00:00:47,262 --> 00:00:49,809
...that is quickly falling from the sky.
10
00:01:07,704 --> 00:01:09,704
This is a true story
11
00:01:09,728 --> 00:01:13,252
It is based on official reports
and eyewitness accounts
12
00:01:15,049 --> 00:01:17,768
In placid skies over Central Canada
13
00:01:17,792 --> 00:01:22,298
Air Canada Flight 143 is just passed
a halfway-mark of its journey
14
00:01:22,323 --> 00:01:25,627
from Montreal to Edmonton Alberta
15
00:01:29,408 --> 00:01:33,306
The plane is carrying 61 passengers
and 8 crew-members
16
00:01:37,939 --> 00:01:40,931
It is July, 23th 1983
17
00:01:43,907 --> 00:01:47,844
Rick Dion is an Air Canada maintenance engineer
18
00:01:47,868 --> 00:01:51,399
I was going to Edmonton
with my wife Pearl
19
00:01:51,423 --> 00:01:54,337
and my young son Chris, who was 4 years old
20
00:01:54,361 --> 00:01:57,719
This was the beginning of a 2 week vacation for us
21
00:01:57,743 --> 00:02:01,711
we were all pretty excited about
going on this new airplane.
22
00:02:01,735 --> 00:02:03,735
Compliment of the Captain
23
00:02:06,423 --> 00:02:09,876
This was my first flight on the modern 767
24
00:02:09,900 --> 00:02:12,813
The company has just acquired them
25
00:02:12,837 --> 00:02:17,368
I was interested in going to the cockpit
to see all this new technology
26
00:02:17,392 --> 00:02:20,399
fit in with the work that I did on aircraft
27
00:02:21,009 --> 00:02:23,798
The Captain on this flight is Bob Pearson
28
00:02:23,822 --> 00:02:29,111
He is 48 years old and
he spent more than 15,000 hours in the air
29
00:02:29,135 --> 00:02:34,767
His first officer is Maurice Quintal,
who has more than 7,000 hours of flying time
30
00:02:36,502 --> 00:02:38,502
Come on in
31
00:02:39,118 --> 00:02:40,501
Pardon me, gentlemen
32
00:02:40,526 --> 00:02:46,119
I knew Bob Pearson from the small flying club
that I attended in St Lazare
33
00:02:46,174 --> 00:02:51,283
He was one of the local pilots there,
that used to do some gliding
34
00:02:51,307 --> 00:02:55,135
He also flew the Ultra-light Lazairs
35
00:02:56,276 --> 00:02:59,205
We had departed heading North-West
36
00:02:59,229 --> 00:03:02,229
a nice, clear sunny day in July
37
00:03:02,253 --> 00:03:05,346
We were at a 39,000 ft
38
00:03:05,370 --> 00:03:10,135
There were few airplanes
that flew that high in 1983
39
00:03:10,159 --> 00:03:16,284
We requested 41,000 ft, which got us
further above the jet-stream out of the West
40
00:03:16,737 --> 00:03:19,885
The crew may have accumulated
a lot of hours in the air
41
00:03:19,909 --> 00:03:21,909
but very few in this plane
42
00:03:22,277 --> 00:03:27,622
It is Boeing's latest and most advanced
wide-body jet: the 767
43
00:03:31,965 --> 00:03:36,615
An army of microprocessors in
the belly of the plane automates so many functions
44
00:03:36,639 --> 00:03:40,006
that the flight-engineer's job has been eliminated
45
00:03:41,631 --> 00:03:46,373
This is one of four 767's
that Air Canada has recently acquired
46
00:03:46,397 --> 00:03:49,936
The plane itself has only 150 hours on it.
47
00:03:52,303 --> 00:03:54,303
Quite a difference here, huh
48
00:03:57,364 --> 00:04:02,495
The cockpit is different in that all
the old instrumentation that we were accustomed to
49
00:04:02,520 --> 00:04:04,336
Mostly was all gone
50
00:04:04,361 --> 00:04:08,731
It was all CRT display
like small TV screens
51
00:04:08,755 --> 00:04:11,730
It was a new high-tech airplane,
52
00:04:11,755 --> 00:04:16,630
which involve quite a change for the crew
53
00:04:16,654 --> 00:04:19,854
and maintenance personnel, people handling it
54
00:04:19,879 --> 00:04:23,832
This was a new aircraft
for both the Captain and I
55
00:04:23,857 --> 00:04:26,746
At that time,
I had 75 hours on that airplane
56
00:04:26,928 --> 00:04:28,928
Everything was new for me
57
00:04:28,952 --> 00:04:33,568
Pilots and maintenance crews
are both still getting to know this airliner
58
00:04:36,193 --> 00:04:38,223
Captain Pearson explains to Dion
59
00:04:38,248 --> 00:04:42,943
how he handled a small problem with
the engines on an earlier flight.
60
00:04:51,995 --> 00:04:53,995
Fuel pressure
61
00:04:54,019 --> 00:04:56,019
Why would that be?
62
00:04:56,340 --> 00:04:59,448
A warning alerts the crew
to critically low pressure
63
00:04:59,473 --> 00:05:02,340
at one of the plane's fuel pumps.
64
00:05:06,676 --> 00:05:09,895
The 767 has three main fuel tanks:
65
00:05:09,919 --> 00:05:12,269
two in the wings which are always used
66
00:05:12,293 --> 00:05:16,011
and one in the CENTER
only used on long distance flights.
67
00:05:17,238 --> 00:05:20,308
Electric fuel pumps draw fuel from each tank
68
00:05:20,332 --> 00:05:22,855
and feed it to the plane's 2 engines
69
00:05:22,879 --> 00:05:26,534
The low pressure warning could mean
that one of the pumps needs maintenance
70
00:05:26,558 --> 00:05:29,273
but it could also be a more serious issue:
71
00:05:29,297 --> 00:05:32,077
a lack of fuel to be pumped
72
00:05:38,983 --> 00:05:41,506
Another low fuel pressure warning sounds
73
00:05:41,530 --> 00:05:44,967
this one from another fuel pump
on the plane's left side
74
00:05:45,115 --> 00:05:48,946
Pearson's Flight Management Computer
tells him he should have plenty of fuel
75
00:05:48,971 --> 00:05:50,701
for the remainder of the trip
76
00:05:50,725 --> 00:05:54,467
The 767 also has separate digital fuel gauges
77
00:05:54,491 --> 00:05:57,967
but on this flight,
those gauges are out of service
78
00:05:58,279 --> 00:06:00,279
The warnings don't make sense
79
00:06:07,271 --> 00:06:10,525
I used to be involved with transferring fuel
80
00:06:10,549 --> 00:06:14,041
and I know that when you're
trying to empty a tank
81
00:06:14,066 --> 00:06:19,095
It will start flashing periodically,
and than the pump will re-prime
82
00:06:19,119 --> 00:06:20,948
and then later go out
83
00:06:20,972 --> 00:06:25,261
In this case,
it appeared to do exactly the same thing
84
00:06:27,245 --> 00:06:31,033
Captain Pearson knows,
that if the left tank is running low
85
00:06:31,058 --> 00:06:33,995
the right tank may be low as well
86
00:06:34,019 --> 00:06:35,706
Let us head for Winnipeg...
87
00:06:35,730 --> 00:06:36,815
...now!
88
00:06:36,839 --> 00:06:41,714
Pearson wants to land as soon as possible
in case he is running out of fuel.
89
00:06:44,651 --> 00:06:50,416
The crew is still more than 700 miles away
from their original destination, Edmonton Alberta
90
00:06:50,441 --> 00:06:53,769
The nearest major airport is Winnipeg, Manitoba
91
00:06:53,793 --> 00:06:56,480
a mere 120 miles away
92
00:06:57,222 --> 00:07:00,300
We're showing lots of fuel on board
on our Flight Management Computer
93
00:07:00,325 --> 00:07:04,434
and normal fuel checks cross checked
with our fuel on our flight-plan
94
00:07:04,911 --> 00:07:07,887
We elected to divert the flight to Winnipeg,
95
00:07:07,911 --> 00:07:11,723
where Air Canada has a main maintenance base
96
00:07:12,848 --> 00:07:14,543
Air Canada 143
97
00:07:16,433 --> 00:07:20,877
Ron Hewett has 20 year experience
as a radar controller.
98
00:07:20,901 --> 00:07:22,901
Yes, sir, we have a problem
99
00:07:22,979 --> 00:07:26,414
We are going to...
...a requesting direct Winnipeg
100
00:07:26,438 --> 00:07:28,438
Air Canada 143 cleared
101
00:07:28,462 --> 00:07:30,768
Take position direct Winnipeg
102
00:07:30,792 --> 00:07:33,104
cleared to maintain 6000 descend
103
00:07:37,892 --> 00:07:41,650
He didn't tell us what the problem was
and it is none of my business
104
00:07:41,674 --> 00:07:44,775
Give him what he wants,
get everybody out of his way
105
00:07:44,800 --> 00:07:46,800
That is about what we do
106
00:07:48,761 --> 00:07:52,721
Pearson now begins to descend from 41,000 ft
107
00:07:58,032 --> 00:08:02,955
The low pressure warnings are spreading
to more and more of the fuel pumps
108
00:08:11,314 --> 00:08:16,165
Quintal instructs the cabin crew
to prepare for an emergency landing
109
00:08:18,264 --> 00:08:20,264
I think we have problems with our fuel system
110
00:08:20,289 --> 00:08:23,532
We are diverting to Winnipeg
111
00:08:27,456 --> 00:08:30,989
All flight attendants to front galley please
112
00:08:31,990 --> 00:08:34,723
I hope these are just false warnings
113
00:08:34,747 --> 00:08:37,395
Rick, can you think of anything we haven't done?
114
00:08:50,219 --> 00:08:52,219
OKAY...
115
00:08:52,243 --> 00:08:54,243
... we've lost the left engine
116
00:08:55,353 --> 00:08:58,048
Losing an engine erases any doubt:
117
00:08:58,072 --> 00:09:01,400
Flight 143 is in fact running out of fuel
118
00:09:02,392 --> 00:09:05,900
OKAY, checklist
single engine landing
119
00:09:07,884 --> 00:09:12,009
Pearson is trained to land a 767 with one engine
120
00:09:12,955 --> 00:09:15,743
No one has ever tried landing with none
121
00:09:18,204 --> 00:09:22,751
He scrambles to get his plane down,
so that he doesn't become the first
122
00:09:25,181 --> 00:09:28,962
With only one engine powering Air Canada 143,
123
00:09:28,986 --> 00:09:32,470
and with the possibility of
the other engine shutting down
124
00:09:32,494 --> 00:09:35,768
the crew prepares the passengers for the worst
125
00:09:38,152 --> 00:09:41,707
Ladies and gentlemen,
this is your in charge flight attendance speaking
126
00:09:41,731 --> 00:09:45,402
Due to mechanical problems
we will be preparing for an emergency landing
127
00:09:45,426 --> 00:09:48,682
Please, return to your seats
and fasten your seatbelts
128
00:09:48,706 --> 00:09:51,222
Your crew is fully trained
to deal with the situation
129
00:09:51,246 --> 00:09:52,167
and as you may have noticed
130
00:09:52,192 --> 00:09:55,300
some crew-members have already
started to prepare the aircraft
131
00:09:55,325 --> 00:10:01,580
I had no idea, like the rest of my crew-members,
that there was a problem with fuel
132
00:10:01,605 --> 00:10:05,800
I had no idea why we were going to Winnipeg
133
00:10:08,113 --> 00:10:09,868
Approach and landing
134
00:10:09,892 --> 00:10:11,892
Flaps will be 20
135
00:10:13,174 --> 00:10:14,751
As they are doing that drill,
136
00:10:14,775 --> 00:10:21,314
the right hand fuel pump low pressure light
was flashing as well
137
00:10:21,642 --> 00:10:23,431
much like it did on the left
138
00:10:23,455 --> 00:10:26,853
They were quite busy
carrying out the first engine out
139
00:10:26,877 --> 00:10:32,400
not watching the pump-lights
which was right at my eyebrows
140
00:10:32,424 --> 00:10:35,681
I knew that there was a shutdown, too
141
00:10:38,861 --> 00:10:40,861
What was that?
142
00:10:58,385 --> 00:11:00,673
How come I have no instruments?
143
00:11:00,697 --> 00:11:06,063
Our beautiful colour engine and
flight instrument displays...
144
00:11:06,088 --> 00:11:08,088
...simply went black
145
00:11:08,112 --> 00:11:10,814
It is exactly what Pearson had feared.
146
00:11:10,838 --> 00:11:13,200
He has lost both engines.
147
00:11:13,224 --> 00:11:19,177
At 26,500
still 75 miles from the nearest major airport...
148
00:11:19,201 --> 00:11:21,201
...he is out of fuel
149
00:11:22,740 --> 00:11:24,740
Air Canada 143, go ahead.
150
00:11:24,764 --> 00:11:26,764
We just lost both engines
151
00:11:26,788 --> 00:11:30,521
When both engines shut off,
152
00:11:30,545 --> 00:11:35,100
I think holy...
I am talking to a dead man
153
00:11:40,811 --> 00:11:44,718
It is highly unlikely
that anybody is going to survive this
154
00:11:45,281 --> 00:11:47,757
I could see them trying to make a turn
155
00:11:47,781 --> 00:11:49,781
and spinning in
156
00:11:50,342 --> 00:11:53,318
An airplane's engine doesn't only provide thrust
157
00:11:53,343 --> 00:11:57,565
They also generate the power
needed to manipulate the plane.
158
00:11:58,218 --> 00:12:00,593
It would be completely uncontrollable,
159
00:12:00,617 --> 00:12:05,858
but modern airliners are like a Swiss army knife
with one last blade hidden away.
160
00:12:05,882 --> 00:12:08,298
In the event of a loss of power,
161
00:12:08,377 --> 00:12:12,478
they automatically deploy the RAT,
or Ram Air Turbine
162
00:12:13,953 --> 00:12:15,415
It is spring-loaded
163
00:12:15,440 --> 00:12:18,631
and the propeller that drives
the small hydraulic pump
164
00:12:18,656 --> 00:12:23,264
is about size of a propeller
you would see like on a little Cessna 150
165
00:12:23,288 --> 00:12:27,920
This arm catapults down into the slipstream
166
00:12:27,944 --> 00:12:31,639
This propeller starts to turn,
drives this hydraulic pump
167
00:12:31,663 --> 00:12:34,897
and gives you basic systems
168
00:12:38,249 --> 00:12:41,803
It was pretty quiet, flying without motors
169
00:12:42,131 --> 00:12:44,546
Pearson knows the time is running out
170
00:12:44,570 --> 00:12:48,162
He needs directions to the closest landing strip
171
00:12:48,186 --> 00:12:50,997
143, This is a mayday
172
00:12:51,022 --> 00:12:54,748
We require a vector
on to the closest available runway
173
00:12:57,335 --> 00:13:02,592
But the loss of the plane's engines
has had an unexpected consequence at ATC
174
00:13:04,170 --> 00:13:05,834
They're gone
175
00:13:05,858 --> 00:13:07,116
They were right here
176
00:13:07,140 --> 00:13:10,021
We have lost them on the screen
177
00:13:10,046 --> 00:13:12,046
I need primary radar
178
00:13:17,163 --> 00:13:22,850
143, We have lost your transponder return
in our attempt to pick up your target now
179
00:13:23,702 --> 00:13:27,209
We work on transponders
it is called secondary radar.
180
00:13:27,489 --> 00:13:32,012
We take the pilot's signal to ping the aircraft
181
00:13:37,910 --> 00:13:40,863
Commercial jetliners are equipped
with a transponder
182
00:13:40,888 --> 00:13:46,614
a device that transmits coded information
which ATC use to determine the plane's location
183
00:13:47,505 --> 00:13:50,380
But when Flight 143 lost its second engine
184
00:13:50,404 --> 00:13:53,567
only a small number of items got back up power
185
00:13:54,333 --> 00:13:59,168
The transponder was not one of them
so the plane disappeared from Hewett's screen
186
00:13:59,192 --> 00:14:02,309
Flight 143 is somewhere East of Winnipeg
187
00:14:02,333 --> 00:14:04,177
but no one knows exactly where,
188
00:14:04,202 --> 00:14:06,357
or how far it is from the airport.
189
00:14:06,381 --> 00:14:08,318
In spite of its enormous weight,
190
00:14:08,343 --> 00:14:12,444
a 767 doesn't plunge from the
sky when it looses its engines
191
00:14:12,468 --> 00:14:17,085
its aerodynamic properties keep it in the air,
but slowly coasting to earth
192
00:14:17,109 --> 00:14:24,679
I was trying to figure
how many miles we were moving ahead
193
00:14:24,703 --> 00:14:29,234
versus how many thousands of feet
we were dropping.
194
00:14:31,188 --> 00:14:35,242
But Quintal doesn't have the instruments
which provide the information he needs
195
00:14:35,267 --> 00:14:37,506
to make that calculation.
196
00:14:37,530 --> 00:14:42,071
Since he lost the plane's signal,
Hewett cannot give Quintal that information either
197
00:14:42,610 --> 00:14:46,623
Controllers hurriedly work to rig up a way
to find the plane
198
00:14:49,162 --> 00:14:52,201
Just before landing, you will hear the command:
'brace for landing'
199
00:14:52,225 --> 00:14:57,122
Brace immediately, and stay braced
until the plane comes to a complete stop
200
00:14:57,146 --> 00:14:59,146
There are two was to brace:
201
00:14:59,170 --> 00:15:04,076
1. Bend Forward:
raise your arms and ends against
202
00:15:04,100 --> 00:15:07,888
Bryce Bell is a businessman
on his way home to Edmonton
203
00:15:07,912 --> 00:15:12,630
As soon as they announced that we were making
a non-scheduled stop in Winnipeg
204
00:15:12,661 --> 00:15:15,607
I immediately wished I hadn't had the two drinks
that I had had
205
00:15:15,632 --> 00:15:18,069
because I thought: You are going
to have a split second here
206
00:15:18,094 --> 00:15:20,686
and this plane is going
to explode in flame
207
00:15:20,711 --> 00:15:26,007
and the decision you make in that split second
will depend on how alert you are
208
00:15:31,554 --> 00:15:35,648
Because their modern equipment
cannot see Air Canada 143
209
00:15:35,672 --> 00:15:41,093
the controller switched to old fashioned radar
which doesn't need a transponder to locate planes
210
00:15:41,117 --> 00:15:45,109
I got to turn up my true radar
(the reflective radar)
211
00:15:45,133 --> 00:15:47,562
which is not nearly as good
212
00:15:47,593 --> 00:15:50,811
and we don't use that at all
213
00:15:52,803 --> 00:15:54,484
OKAY, I've got it
214
00:15:54,508 --> 00:15:57,484
65 from Winnipeg, 45 from Gimli
215
00:15:57,508 --> 00:16:03,836
143, we have you at 65 miles from Winnipeg
and approx 45 miles from Gimli
216
00:16:04,821 --> 00:16:10,008
For the first time since losing power,
the pilots know their distance to Winnipeg
217
00:16:11,196 --> 00:16:13,649
We gaan gezellig naar Winnipeg
218
00:16:14,789 --> 00:16:18,641
Quintal, however, thinks that Gimli is a safer bet
219
00:16:20,462 --> 00:16:24,024
Gimli, Manitoba has
a decommissioned air force base
220
00:16:24,048 --> 00:16:26,962
It is about 20 miles closer than Winnipeg
221
00:16:27,657 --> 00:16:32,161
As luck would have it, Maurice Quintal
trained at Gimli while in the armed forces
222
00:16:32,186 --> 00:16:34,186
He knows it well
223
00:16:37,061 --> 00:16:39,061
45 miles to Gimli
224
00:16:39,475 --> 00:16:41,475
There is long runway
225
00:16:42,686 --> 00:16:46,178
Is there emergency equipment at Gimli?
226
00:16:46,475 --> 00:16:51,529
Negative emergency equipment at all,
just one runway available, I believe.
227
00:16:51,553 --> 00:16:54,896
No control tower and no information on it
228
00:16:54,920 --> 00:16:58,521
Pearson must consider
the possibility of a crash landing
229
00:16:58,545 --> 00:17:03,224
If he has any chance of making it to Winnipeg,
which has full emergency support
230
00:17:03,248 --> 00:17:05,248
he knows he must try for it.
231
00:17:05,272 --> 00:17:08,388
OKAY, then we would prefer Winnipeg
232
00:17:09,919 --> 00:17:12,848
Fine, 143, continue your present heading
233
00:17:14,059 --> 00:17:17,152
It was about regrets
Things I hadn't done in my life
234
00:17:17,285 --> 00:17:21,879
It was about ways I've treated the odd person
here or there that I wish it more gently
235
00:17:21,903 --> 00:17:24,700
It was about how stupid I was
at some of the things
236
00:17:24,725 --> 00:17:27,677
I used to make big issues out of
that are so insignificantly
237
00:17:27,702 --> 00:17:30,646
when it really comes down to
what real reality is about:
238
00:17:30,670 --> 00:17:32,670
It was pretty devastating.
239
00:17:33,645 --> 00:17:39,333
And I remember telling a mother with a baby
and I had...
240
00:17:47,059 --> 00:17:48,536
My daughter Victoria
241
00:17:49,887 --> 00:17:54,331
telling this woman that it will be okay
and I did
242
00:17:54,371 --> 00:17:58,460
I was so proud of myself
that I could be so straight with her
243
00:17:59,241 --> 00:18:03,670
and tell her that it was going to be alright
and really looking her in the eyes
244
00:18:04,396 --> 00:18:06,724
OKAY, how far from the field are we now
245
00:18:06,749 --> 00:18:08,693
You are 35 miles...
246
00:18:08,717 --> 00:18:11,647
...39 miles from Winnipeg
247
00:18:13,337 --> 00:18:16,751
Now that controllers can see Flight 143 on radar
248
00:18:16,776 --> 00:18:19,393
they can provide Quintal
with the information he needs
249
00:18:19,418 --> 00:18:22,143
to figure out if he can
glide as far as Winnipeg
250
00:18:24,018 --> 00:18:26,018
1.5
251
00:18:26,478 --> 00:18:31,579
About 8500 ft above the ground,
Captain Pearson can see his destination
252
00:18:31,604 --> 00:18:34,760
Winnipeg's Airport is less than 35 miles away
253
00:18:34,784 --> 00:18:36,127
We are visual
254
00:18:36,151 --> 00:18:39,338
but the news from Quintal is not good
255
00:18:39,362 --> 00:18:41,651
Bob,
256
00:18:41,675 --> 00:18:49,518
Maurice was keeping track of our distance
by input from Winnipeg ATC
257
00:18:49,542 --> 00:18:51,542
and out altitude
258
00:18:51,566 --> 00:18:54,826
and calculated our profile
and came to the conclusion that...
259
00:18:54,851 --> 00:18:57,800
...we might not make the
runway to Winnipeg
260
00:18:57,824 --> 00:19:02,386
We can last maybe another 20 miles
We are not making Winnipeg
261
00:19:02,659 --> 00:19:05,475
Quintal has calculated
that at the rate they are falling
262
00:19:05,499 --> 00:19:09,330
they would hit the ground a full 15 miles
short of the runway
263
00:19:09,354 --> 00:19:11,354
How far here from Gimli?
264
00:19:14,354 --> 00:19:17,932
You are approx 12 miles from Gimli right now
265
00:19:17,956 --> 00:19:19,956
Where is it?
266
00:19:24,721 --> 00:19:26,112
On your right
267
00:19:26,143 --> 00:19:29,955
Turn right to a heading of 345
268
00:19:30,564 --> 00:19:32,564
I will say you have 10 miles to fly
269
00:19:32,588 --> 00:19:34,471
OKAY, fine
270
00:19:34,496 --> 00:19:36,612
We are going to go there
271
00:19:36,946 --> 00:19:38,946
I am going to check up my family
272
00:19:38,971 --> 00:19:41,875
You guys don't need me right now, huh?
273
00:20:00,102 --> 00:20:04,844
When I went finally to sit down in my seat,
this is where I thought:
274
00:20:05,774 --> 00:20:07,936
This is it
275
00:20:19,760 --> 00:20:21,760
Landing gear down
276
00:20:21,784 --> 00:20:25,299
First officer Quintal lowers the landing gear
277
00:20:25,323 --> 00:20:29,580
Because there is no hydraulic power,
Quintal does what is known as a gravity drop
278
00:20:29,604 --> 00:20:33,088
letting the gear's own weight drop and lock it
into place
279
00:20:33,112 --> 00:20:34,878
The two main gear are heavy,
280
00:20:34,903 --> 00:20:38,791
they fall immediately
and two green lights confirm they've locked
281
00:20:38,815 --> 00:20:42,416
but the nose gear is lighter,
it doesn't lock
282
00:20:42,440 --> 00:20:47,526
We could hear the main gear clearly
falling and locking
283
00:20:47,550 --> 00:20:52,401
I was not aware
that the nose gear was not down and locked
284
00:20:52,425 --> 00:20:58,714
It was the last minute and
if it is something that you cannot control...
285
00:20:58,738 --> 00:21:01,237
...you don't talk about it,
you don't mention it
286
00:21:01,416 --> 00:21:03,392
The main thing was:
287
00:21:03,416 --> 00:21:06,017
bring the aircraft on the runway
288
00:21:06,041 --> 00:21:08,041
5 miles to touchdown
289
00:21:08,479 --> 00:21:10,479
We have the field inside
290
00:21:10,503 --> 00:21:11,901
5 Miles from Gimli,
291
00:21:11,926 --> 00:21:15,768
Pearson and Quintal finally
see a runway they can land on
292
00:21:15,792 --> 00:21:17,792
but there is a problem
293
00:21:19,284 --> 00:21:21,284
It is going to be too steep, too fast
294
00:21:21,581 --> 00:21:23,581
Yeah,. I know
295
00:21:25,558 --> 00:21:29,370
Pearson is almost at the runway,
but he is much too high above it
296
00:21:29,394 --> 00:21:33,456
If he comes down at a normal descend rate,
he'll miss the landing-strip
297
00:21:33,480 --> 00:21:38,480
but if he comes down steeply,
his plane will gather a dangerous amount of speed
298
00:21:38,504 --> 00:21:42,386
he won't be able to stop
before the end of the runway
299
00:21:42,410 --> 00:21:47,103
With a normal approach we have
leading edge and trailing edge flaps
300
00:21:47,128 --> 00:21:49,722
which allow us to slow
the air-plane down
301
00:21:49,746 --> 00:21:52,277
and fly at a slower speed, safely.
302
00:21:52,301 --> 00:21:57,019
We did not have real flaps
as they run off the main hydraulic system
303
00:21:57,043 --> 00:21:59,043
So, what are we going to do?
304
00:21:59,067 --> 00:22:01,847
So we discuss we had two possibilities
305
00:22:01,872 --> 00:22:06,090
One of them was to 360° turn
306
00:22:06,114 --> 00:22:10,612
and lose the excess of altitude
307
00:22:10,637 --> 00:22:14,332
On the other hand,
I thought, it would take about 3 minutes
308
00:22:14,356 --> 00:22:20,183
and we were already descending
at a rate of 2500 ft/min
309
00:22:20,207 --> 00:22:22,564
Only about 3000 ft
above the ground,
310
00:22:22,589 --> 00:22:25,621
the plane doesn't have enough
altitude to make a full circle
311
00:22:25,645 --> 00:22:29,027
It would hit the ground
before making it back to the landing strip
312
00:22:29,051 --> 00:22:31,785
Pearson chooses a 2nd option
313
00:22:33,082 --> 00:22:35,082
Well, I guess I 'll just slip it
314
00:22:38,582 --> 00:22:41,816
Pearson decides to try a manoeuvre,
called a side slip
315
00:22:41,840 --> 00:22:46,800
practically unheard of on commercial airliners,
but sometimes used by glider-pilots
316
00:22:46,824 --> 00:22:50,668
and Bob Pearson has
a lot of experience flying gliders
317
00:22:50,692 --> 00:22:54,621
I am just going to slip it down
till we are almost at the end of the runway
318
00:22:56,848 --> 00:23:00,449
Side slipping involves
what is known as crossing the controls
319
00:23:01,707 --> 00:23:05,535
Pearson plans to force the aircraft
into a sideways free-fall
320
00:23:05,559 --> 00:23:09,988
allowing it to drop quickly
without increasing its forward airspeed
321
00:23:10,215 --> 00:23:13,824
Pearson has never actually performed a side slip
in a commercial aircraft
322
00:23:13,848 --> 00:23:17,746
but he is attempting one now
in a Boeing 767
323
00:23:18,535 --> 00:23:27,123
The only way that I could control our speed
was to induce drag in the fuselage
324
00:23:27,147 --> 00:23:31,225
by cross controlling
the rudder and the elevators on the tail
325
00:23:31,249 --> 00:23:33,249
and the ailerons and the wingtips
326
00:23:33,273 --> 00:23:37,991
and causing the aircraft into a configuration
327
00:23:38,015 --> 00:23:42,991
Then, I can vary that
to increase or decrease our speed
328
00:23:43,015 --> 00:23:45,585
or increase or decrease our descend rate
329
00:23:46,124 --> 00:23:50,028
Pearson controls the plane's descend
by using his rudders and ailerons
330
00:23:50,053 --> 00:23:51,921
to chance the angle of the plane
331
00:23:52,358 --> 00:23:55,873
Crossing the controls involves
tipping the wings in one direction
332
00:23:55,897 --> 00:23:58,686
but turning the aircraft in the opposite direction
333
00:23:58,710 --> 00:24:01,483
putting it side ways into the oncoming air
334
00:24:02,812 --> 00:24:06,280
As Flight 143 begins to drop towards the earth
335
00:24:06,304 --> 00:24:10,124
Quintal is about to discover something
he did not expect
336
00:24:10,148 --> 00:24:14,179
The runway he trained at 15 years ago
337
00:24:18,352 --> 00:24:20,703
is no longer a runway
338
00:24:24,164 --> 00:24:26,930
Captain Bob Pearson is out of fuel
339
00:24:26,954 --> 00:24:30,006
out of engines, out of options
340
00:24:30,030 --> 00:24:34,912
If he can't line up with the runway at Gimli,
he doesn't get a second chance
341
00:24:40,642 --> 00:24:42,900
Pearson turns the yoke left
342
00:24:42,924 --> 00:24:45,486
and pushes the rudders to the right
343
00:24:45,510 --> 00:24:47,510
The plane slips...
344
00:24:48,229 --> 00:24:50,229
...to its left
345
00:24:53,088 --> 00:24:56,713
We were sitting in the CENTER,
which is the heart of the air-plane
346
00:24:56,737 --> 00:24:58,447
so it is pretty solid there
347
00:24:58,471 --> 00:25:03,385
I thought there is a real good chance here
that we'll be Al right
348
00:25:04,190 --> 00:25:10,033
However, when he put the air-plane into a side-slip
all that went out the window was
349
00:25:10,057 --> 00:25:14,853
If he hits the wing or something,
he starts to catapult and roll
350
00:25:14,877 --> 00:25:16,611
that is not going to work anymore
351
00:25:16,635 --> 00:25:21,533
The 767 loses altitude quickly,
ploughing sideways through the air
352
00:25:21,572 --> 00:25:25,135
When I looked to the left of the aircraft,
353
00:25:25,159 --> 00:25:27,963
I was looking directly on the ground
354
00:25:28,869 --> 00:25:35,415
because the air-plane is angled quite,
maybe 60° of bank
355
00:25:35,439 --> 00:25:40,962
The bank angle was quite high
and the nose of the aircraft was quite high
356
00:25:40,986 --> 00:25:44,220
It was an awkward moment
357
00:25:44,244 --> 00:25:46,167
If it was awkward for me,
358
00:25:46,192 --> 00:25:51,143
I can imagine for the passengers,
it must really have felt odd
359
00:25:51,167 --> 00:25:54,215
I saw a sand-trap from this golf-course
360
00:25:54,239 --> 00:25:58,184
And I thought:
We are going to crash!
361
00:25:58,208 --> 00:26:01,168
Pearson must maintain a crucial balance:
362
00:26:01,192 --> 00:26:04,520
He has got to slow the plane enough
to be able to land safely
363
00:26:04,544 --> 00:26:08,449
But if he slows down too much,
the airliner could lose his lift...
364
00:26:08,473 --> 00:26:09,926
...and plummet to the ground
365
00:26:09,950 --> 00:26:14,988
When a pilot is normally landing an air-plane
he is manoeuvring the flight controls
366
00:26:15,020 --> 00:26:18,198
and operating the thrust levers...
367
00:26:18,223 --> 00:26:20,934
...pretty continuously at most landings.
368
00:26:20,958 --> 00:26:25,082
So, I was doing the same thing
(without the thrust levers)
369
00:26:28,659 --> 00:26:35,401
This is where I thought at my daughter Victoria,
being alone with my husband
370
00:26:36,513 --> 00:26:40,276
and how he was going to cope with our daughter
371
00:26:40,300 --> 00:26:43,651
and how she was going to cope without having a mom
372
00:26:45,389 --> 00:26:48,553
As they approach,
Pearson focuses on his target:
373
00:26:48,577 --> 00:26:50,818
The threshold of the runway.
374
00:26:50,842 --> 00:26:54,527
I got tunnel-vision like I have never had it before
375
00:26:54,551 --> 00:27:00,215
It was just our speed and our relationship
with the threshold of the runway
376
00:27:00,239 --> 00:27:03,520
But now, only hundreds
of feet from the ground,
377
00:27:03,545 --> 00:27:06,903
Quintal sees that their troubles
are far from over
378
00:27:09,380 --> 00:27:12,130
The Gimli landing strip has been converted...
379
00:27:16,247 --> 00:27:18,247
...into a drag racing strip.
380
00:27:21,872 --> 00:27:25,371
Today is Saturday
and it is not just a race-day.
381
00:27:25,980 --> 00:27:28,691
It is a family day on the Gimli strip
382
00:27:29,902 --> 00:27:32,409
Racing is done for the day,
383
00:27:32,433 --> 00:27:36,776
but the airfield is filled with
members of the local sport-scar-club,
384
00:27:38,245 --> 00:27:41,401
camping out with their families for the weekend.
385
00:27:46,511 --> 00:27:50,800
Two children have decided
to peddle the length of the runway.
386
00:27:50,824 --> 00:27:53,378
They don't hear the plane coming for them
387
00:27:53,402 --> 00:27:56,183
without engines, it is silent
388
00:27:56,207 --> 00:27:59,972
And one thing the 767 doesn't have...
389
00:27:59,996 --> 00:28:01,527
...is a horn.
390
00:28:01,551 --> 00:28:03,551
Brace, brace for landing
391
00:28:14,177 --> 00:28:16,762
The nose hit with quite a bang on the runway
392
00:28:16,786 --> 00:28:18,942
It was like a shotgun going off within feet
393
00:28:18,966 --> 00:28:21,755
The front landing-gear gives out immediately
394
00:28:21,779 --> 00:28:25,098
Pearson brakes hard, 2 tyres blow out.
395
00:28:26,567 --> 00:28:29,112
The bottom of the right engine scrapes the runway.
396
00:28:29,137 --> 00:28:31,137
I was a robot, no emotion at all
397
00:28:32,505 --> 00:28:35,504
Finally, Pearson sees what is in their path
398
00:28:35,528 --> 00:28:38,912
I looked up and could see two boys on bicycles.
399
00:28:38,936 --> 00:28:44,708
They must have been probably a 1000 ft
down the runway for my position when I saw them
400
00:28:44,732 --> 00:28:48,209
At one point,
I could see he raise his head
401
00:28:48,233 --> 00:28:52,122
And his surprise
there is this big aircraft
402
00:28:52,146 --> 00:28:55,778
I can still remember
the look of terror on their faces
403
00:28:55,802 --> 00:28:58,685
So, they were close enough for me to see that.
404
00:29:00,599 --> 00:29:02,575
With no nose-gear to steer with,
405
00:29:02,600 --> 00:29:05,443
Pearson's only hope of driving
the plane left or right
406
00:29:05,468 --> 00:29:09,593
is by varying the brake pressure
on the two main landing gear
407
00:29:09,617 --> 00:29:13,921
That is where my heart
started to pitter patter a little bit
408
00:29:13,945 --> 00:29:19,382
The kids panic and try to outrun a plane
that is travelling about 200 mph
409
00:29:19,406 --> 00:29:22,156
I knew I couldn't take the air-plane
into these boys
410
00:29:22,181 --> 00:29:26,249
and I was going to take it off
into the grass in the race-side
411
00:29:26,429 --> 00:29:30,507
There were campers
along the West-side of the runway
412
00:29:30,531 --> 00:29:34,116
that I didn't notice until after
we've touched down
413
00:29:34,382 --> 00:29:36,046
The nose was on the ground
414
00:29:36,071 --> 00:29:41,391
and I can still remember at the left side
people standing by their barbecues.
415
00:29:41,415 --> 00:29:46,040
Dino Calvert is at the track with his friends
for a weekend of racing.
416
00:29:46,219 --> 00:29:50,015
One of the gentlemen in the pits
suddenly jumped in his car, he took off
417
00:29:51,032 --> 00:29:54,954
you don't drive like that in a pits usually
418
00:29:54,978 --> 00:29:58,883
I looked up and all I could see was smoke rising
419
00:29:58,907 --> 00:30:02,211
Pearson does all he can to stop the plane in time
420
00:30:02,235 --> 00:30:04,235
Holy crow
421
00:30:10,157 --> 00:30:14,633
The plane ploughs into a guard rail,
installed on the middle of the runway
422
00:30:24,098 --> 00:30:26,809
17 minutes after running out of fuel,
423
00:30:26,834 --> 00:30:30,920
Air Canada Flight 143 comes to a final stop
on the ground.
424
00:30:33,716 --> 00:30:38,169
Somebody yelled: Yahoo! or something
and then people started applauding
425
00:30:38,193 --> 00:30:40,958
We were so grateful, we made it!
426
00:30:40,982 --> 00:30:44,430
When you believe you are going to crash,
427
00:30:44,462 --> 00:30:48,247
you do believe that the air-plane
is going to break apart
428
00:30:48,271 --> 00:30:50,927
You are going to have fire
429
00:30:50,951 --> 00:30:52,951
EVACUATE!
430
00:30:54,998 --> 00:30:57,567
Thick smoke is quickly filling the cabin
431
00:30:57,591 --> 00:30:59,591
The crew doesn't take any chances:
432
00:30:59,615 --> 00:31:02,722
They want everyone off the plane
as quickly as possible
433
00:31:02,746 --> 00:31:08,340
There was a sense of joy
and then a panic
434
00:31:08,365 --> 00:31:11,206
We've got to get out of here
435
00:31:11,519 --> 00:31:13,327
Less than 2 months earlier,
436
00:31:13,352 --> 00:31:17,972
an Air Canada DC-9 made a successful
emergency landing in Cincinnati
437
00:31:17,996 --> 00:31:22,878
only to burst into flames on the tarmac
before all the passengers could get off:
438
00:31:22,902 --> 00:31:25,394
23 people died.
439
00:31:25,419 --> 00:31:29,889
The crew and passengers of this flight
want to avoid a similar faith
440
00:31:30,726 --> 00:31:35,749
It took maybe just a few seconds
to come to a full hold on the runway,
441
00:31:35,773 --> 00:31:39,124
but the cockpit was full of smoke
442
00:31:39,148 --> 00:31:41,148
Passenger evacuation checklist
443
00:31:43,366 --> 00:31:45,655
Fuel shut off
444
00:31:45,679 --> 00:31:47,679
Cabin pressurized
445
00:31:48,000 --> 00:31:50,000
Electrics off
446
00:31:50,024 --> 00:31:51,188
Checklist complete
447
00:31:51,212 --> 00:31:53,212
Time to get out of here
448
00:31:57,852 --> 00:31:59,852
Come on guys, get a fire extinguisher
449
00:31:59,876 --> 00:32:02,633
We grabbed a fire extinguisher on our way
450
00:32:02,657 --> 00:32:07,211
You never go to a fire at a racetrack
without having a fire extinguisher with you
451
00:32:07,235 --> 00:32:09,992
And we run up towards it
452
00:32:10,016 --> 00:32:15,156
the doors open up and you see the chutes come of,
like a spider has growing legs
453
00:32:15,180 --> 00:32:21,062
The plane ended up eventually standing almost
what appeared to be almost on its nose
454
00:32:21,461 --> 00:32:26,343
When I opened my door,
and I saw that the chute was so steep
455
00:32:26,367 --> 00:32:31,382
I thought: Oh, my goodness,
how do I get these passengers to go down?
456
00:32:31,406 --> 00:32:37,351
Due to the nose-down angle of the plane,
the 2 rear slides don't reach the ground
457
00:32:39,914 --> 00:32:43,124
10 people are slightly injured
during the evacuation
458
00:32:43,148 --> 00:32:46,031
most of them coming down the steep rear slides.
459
00:32:46,055 --> 00:32:52,680
I heard on the West radar frequency,
one of the 767s says:
460
00:32:53,360 --> 00:32:56,750
He is down OKAY,
He is in one piece
461
00:33:02,070 --> 00:33:04,834
I said: OKAY!
462
00:33:04,859 --> 00:33:09,859
because all of these people were going to sleep
in their own bed that night
463
00:33:16,983 --> 00:33:20,968
There is still a lot of smoke,
coming from the plane's nose
464
00:33:23,155 --> 00:33:27,967
It turned out it was about 6 inches of insulation
between the inner and outer skin...
465
00:33:27,991 --> 00:33:31,389
...from friction,
that was starting to burn
466
00:33:31,413 --> 00:33:33,413
The flight attendances have good news:
467
00:33:33,437 --> 00:33:36,358
all 61 passengers have made it off the plane
468
00:33:36,382 --> 00:33:39,491
There is not so much as a single serious injury
469
00:33:48,227 --> 00:33:51,617
Bob Pearson has done what no one has done before:
470
00:33:51,641 --> 00:33:58,445
he safely landed a 767 with no engines,
gliding to safety from more than 26,000 ft
471
00:34:09,327 --> 00:34:12,500
The event made
international headlines immediately
472
00:34:12,524 --> 00:34:17,188
People are already asking how one of the most
sophisticated passenger-planes in the world
473
00:34:17,213 --> 00:34:19,563
could have run out of fuel
474
00:34:25,387 --> 00:34:29,160
By the next day,
the investigations has already begun.
475
00:34:29,332 --> 00:34:33,642
Bill Taylor and Diane Rocheleau
of Canada's Aviation Safety Bureau
476
00:34:33,667 --> 00:34:36,636
are among the first
investigators at the scene
477
00:34:36,660 --> 00:34:41,784
I was a junior mechanical engineer at the time
I've been working for transport Canada for a year
478
00:34:41,808 --> 00:34:44,722
Going to the field for the first time
was very exciting
479
00:34:44,746 --> 00:34:48,339
It was new,
it was a major aircraft
480
00:34:48,699 --> 00:34:52,222
Once we got into
the fuel-quantity indicating system
481
00:34:52,246 --> 00:34:59,753
I left Diane to deal with the specifics
of the computer system
482
00:34:59,777 --> 00:35:04,167
First, Bill Taylor needs to confirm
what everyone has been telling him:
483
00:35:04,191 --> 00:35:06,191
that the plane is out of fuel
484
00:35:07,214 --> 00:35:12,691
Investigators drain the tanks,
collecting less than 17 gallons of fuel
485
00:35:12,715 --> 00:35:16,971
The 767 can hold almost 24,000 gallons
486
00:35:17,690 --> 00:35:22,058
It is like having 5 tablespoons of fuel
in a midsize car
487
00:35:22,839 --> 00:35:27,652
Taylor next needs to examine the possibility
that the fuel leaked out during the flight
488
00:35:27,676 --> 00:35:32,683
The other checks involved
looking for any evidence of fuel having been lost
489
00:35:33,081 --> 00:35:38,229
I even went so far as to go into
what they call the dry bay of the aircraft
490
00:35:39,081 --> 00:35:41,221
I'm a bit claustrophobic, so
491
00:35:41,246 --> 00:35:44,940
I really wasn't too enthusiastic about
going up in there,
492
00:35:44,965 --> 00:35:48,527
but I crawled up and had a
look around with the flashlight
493
00:35:48,552 --> 00:35:54,005
and confirmed that there was no
evidence of fuel having been lost in there
494
00:35:54,029 --> 00:35:56,503
That leaves Taylor with only one conclusion:
495
00:35:56,527 --> 00:35:59,747
Flight 143 took off without enough fuel
496
00:35:59,771 --> 00:36:03,099
Now, investigators need to find out why
497
00:36:04,490 --> 00:36:07,997
Diane Rocheleau begins looking
for the answer to that question
498
00:36:08,022 --> 00:36:12,740
in the plane's sophisticated electronics bay,
located beneath the cabin
499
00:36:12,764 --> 00:36:16,107
The 767 was a newer type aircraft,
500
00:36:16,131 --> 00:36:21,334
It did have a lot of computerized systems
and I guess back in 1982
501
00:36:21,358 --> 00:36:27,928
These were coming on to the market at a fast rate
and they were newer types of electronic system
502
00:36:30,319 --> 00:36:35,381
Rocheleau confirms that a computerized unit,
the digital fuel gauge processor,
503
00:36:35,405 --> 00:36:38,022
had been malfunctioning on this plane.
504
00:36:38,046 --> 00:36:41,803
There was no spare in Montreal,
so it couldn't be replaced.
505
00:36:43,054 --> 00:36:46,007
Rocheleau takes the component for testing
506
00:36:46,032 --> 00:36:49,254
It was decided early on
that the processing unit
507
00:36:49,279 --> 00:36:54,085
will be taken to the manufacturer,
Honeywell in Indianapolis, for testing.
508
00:36:54,109 --> 00:37:00,265
And I was tasked with taking the unit,
so we went through all the testing procedure
509
00:37:00,289 --> 00:37:04,789
At one point we did discover
that it was a malfunction with the unit
510
00:37:04,813 --> 00:37:10,016
During the testing, we went more and more in depth
and we found out that one of the circuits
511
00:37:10,040 --> 00:37:13,828
It is called an inductor coil,
it was a very small part
512
00:37:13,852 --> 00:37:19,050
It was encapsulated at the manufacturer
Encapsulated means it is covered with plastic
513
00:37:19,075 --> 00:37:20,606
You cannot visually see it,
514
00:37:20,631 --> 00:37:25,169
because it is covered with plastic
and you cannot see the coil itself
515
00:37:25,193 --> 00:37:28,194
Once we took over the plastic case
516
00:37:28,219 --> 00:37:31,641
we could see that the solder joint
had not been made properly
517
00:37:31,665 --> 00:37:34,461
which caused the malfunction in the system
518
00:37:36,680 --> 00:37:41,711
The faulty processor explains why
Pearson didn't have fuel gauges for the flight
519
00:37:41,735 --> 00:37:45,109
but doesn't explain why he didn't have enough fuel
520
00:37:45,133 --> 00:37:48,953
The inoperative gauges were clearly flagged
521
00:37:48,977 --> 00:37:53,602
Ground crews wouldn't have relied on them
when they were fuelling the plane
522
00:37:53,626 --> 00:37:58,002
Investigators confirm that the ground-crew
did perform a manual check of the fuel
523
00:37:58,027 --> 00:37:59,415
before take off
524
00:38:01,993 --> 00:38:03,993
I just need to know what you did next
525
00:38:04,625 --> 00:38:07,113
We did a manual check of both tanks
526
00:38:08,550 --> 00:38:11,315
then, we pump enough fuel for the trip
527
00:38:11,682 --> 00:38:15,767
Flight 143 should have taken off
with enough fuel for the trip
528
00:38:15,791 --> 00:38:17,791
Okay, thanks...
529
00:38:19,603 --> 00:38:21,603
...it helps
530
00:38:29,027 --> 00:38:34,316
Investigators now have to figure out
how one of the world's most advanced jetliners
531
00:38:34,691 --> 00:38:38,300
took off with half the fuel,
necessary for its flight
532
00:38:41,253 --> 00:38:44,893
The investigators know,
that with its fuel gauges out of service
533
00:38:44,917 --> 00:38:48,471
Flight 143's fuel tanks were checked manually
534
00:38:48,495 --> 00:38:52,588
Then, the fuel for the trip to Edmonton
was added to the tanks
535
00:38:57,642 --> 00:39:00,290
But before the plane could be given more fuel,
536
00:39:00,315 --> 00:39:02,962
a crucial calculation had to be carried out
537
00:39:06,314 --> 00:39:10,579
Pilots need to know
the weight of the fuel on their plane
538
00:39:11,376 --> 00:39:14,704
but fuel trucks pump jet-fuel by volume
539
00:39:19,556 --> 00:39:22,399
In order for pilots and fuellers to communicate
540
00:39:22,423 --> 00:39:27,430
a simple routine translation between
volume and weight has to be made
541
00:39:41,054 --> 00:39:45,054
Investigators check and double-check that math.
542
00:39:51,763 --> 00:39:58,020
The fuelling records from the day of the accident
provide the answers they have been looking for
543
00:40:02,543 --> 00:40:04,744
This is a typical fuelling record
544
00:40:04,768 --> 00:40:09,363
But when investigators examine
the calculations for Flight 143
545
00:40:14,043 --> 00:40:16,918
...they look anything but straightforward
546
00:40:16,942 --> 00:40:21,598
The document clearly shows the amount of fuel
in the right and left tanks
547
00:40:21,622 --> 00:40:25,598
but investigators are troubled
by two particular numbers
548
00:40:25,622 --> 00:40:28,465
One converts volume to kilograms
549
00:40:28,489 --> 00:40:30,489
the other converts it to pounds
550
00:40:30,513 --> 00:40:32,513
They shouldn't be using both
551
00:40:37,086 --> 00:40:40,453
So, did you convert to pounds, or to kilograms?
552
00:40:40,477 --> 00:40:42,477
To pound...
553
00:40:43,469 --> 00:40:45,469
...no, to kilo
554
00:40:49,203 --> 00:40:51,500
Can I see that again?
555
00:40:51,524 --> 00:40:57,477
Further interviews with the technicians and crew
reveal that the events on Flight 143
556
00:40:59,243 --> 00:41:03,149
were caused by human error,
involving poor calculations
557
00:41:03,180 --> 00:41:05,508
and ultimately inadequate training
558
00:41:08,703 --> 00:41:13,373
The technicians, refuelling Flight 143,
got muddled in their calculations
559
00:41:13,398 --> 00:41:16,203
while converting the volume
coming out of the fuel truck
560
00:41:16,227 --> 00:41:18,788
to the weight of the fuel in the tanks
561
00:41:20,671 --> 00:41:24,965
No one who saw the calculations that day
noticed the basic error
562
00:41:29,059 --> 00:41:30,502
In 1983,
563
00:41:30,527 --> 00:41:34,808
Canadian ground crews were used to converting
the amount of fuel leaving their trucks,
564
00:41:34,833 --> 00:41:36,566
into pounds
565
00:41:38,723 --> 00:41:44,551
The 767 was the first plane in Air Canada's fleet
to have metric fuel gauges
566
00:41:48,168 --> 00:41:50,753
Its fuel should have been measured not in pounds,
567
00:41:50,777 --> 00:41:54,082
but in kg s, which requires a different calculation
568
00:41:56,684 --> 00:42:02,973
Flight 143 needed 22,300 kg for the trip
569
00:42:02,997 --> 00:42:09,450
But pilots and technicians let it leave
with 22,300 lbs instead
570
00:42:10,380 --> 00:42:15,630
Because a pound is about half a kilogram,
the plane only got half the fuel it required
571
00:42:15,654 --> 00:42:19,872
which explains why Pearson's flight computer
told him he had plenty of fuel
572
00:42:19,896 --> 00:42:23,380
He entered the wrong amount of fuel to start with
573
00:42:23,404 --> 00:42:27,232
In the past,
the flight engineer calculated the fuel loads
574
00:42:27,256 --> 00:42:30,029
This accident raises an important question:
575
00:42:30,053 --> 00:42:33,342
Who's job was it with the two men crew?
576
00:42:33,373 --> 00:42:39,326
Better training is definitively an issue
in an incident just as that
577
00:42:39,350 --> 00:42:41,908
If everyone is trained
578
00:42:41,933 --> 00:42:48,209
and the lines are drawn as to
who is responsible for what
579
00:42:48,233 --> 00:42:52,978
then, there is no ambiguity on it,
580
00:42:53,002 --> 00:42:55,845
People know what they are responsible for
581
00:42:55,869 --> 00:42:59,822
In this case, it was open ended
582
00:42:59,846 --> 00:43:05,588
they were not aware who was responsible.
583
00:43:07,776 --> 00:43:11,244
A subsequent enquiry found that
none of those involved that day
584
00:43:11,269 --> 00:43:13,745
was trained in metric calculations
585
00:43:13,769 --> 00:43:15,550
Not the ground-technicians...
586
00:43:15,575 --> 00:43:17,575
...not the pilots
587
00:43:18,880 --> 00:43:21,411
I had not received any...
588
00:43:21,435 --> 00:43:26,880
neither of us had received any training at all,
and do these calculations
589
00:43:27,669 --> 00:43:31,809
The computer that had replaced
the 767's flight engineer was broken
590
00:43:31,833 --> 00:43:34,419
and no one knew who should be doing its job
591
00:43:34,443 --> 00:43:38,013
Air Canada 143 was essentially down a man
592
00:43:38,037 --> 00:43:41,989
The goal is to prevent a recurrence,
this particular event
593
00:43:42,013 --> 00:43:46,823
We also find out other system
that might have been either at fault
594
00:43:46,848 --> 00:43:50,063
or maybe they could cause
a problem in the future
595
00:43:50,088 --> 00:43:53,074
and you do try to
prevent a recurrence
596
00:43:57,825 --> 00:44:03,653
It took a string of mechanical and human failures
for Flight 143 to run out of fuel
597
00:44:03,880 --> 00:44:07,520
but another failure that day
may have saved some lives
598
00:44:09,622 --> 00:44:12,192
If the plane's nose-gear had not collapsed,
599
00:44:12,216 --> 00:44:15,356
it would have taken Pearson much longer to stop
600
00:44:15,466 --> 00:44:19,294
The plane could have slid into the people
who were at the strip that day.
601
00:44:19,318 --> 00:44:22,262
which would have had catastrophic results
602
00:44:22,286 --> 00:44:25,887
There could have been more injuries
or even loss of life
603
00:44:28,442 --> 00:44:32,731
Pearson and Quintal were partly blamed
for their roles in the incident.
604
00:44:32,755 --> 00:44:36,764
A government enquiry recommended that
Air Canada re-evaluate the training
605
00:44:36,789 --> 00:44:41,359
of flight-crews and ground-technicians
in metric fuel conversions.
606
00:44:41,632 --> 00:44:45,257
It also recommended that the airline
keep more spare parts,
607
00:44:45,281 --> 00:44:47,655
such as fuel gauge processors.
608
00:44:49,663 --> 00:44:56,709
Rick Dion retired in 2003 after a long career
as Air Canada's coordinator of maintenance control
609
00:44:57,537 --> 00:45:02,763
First Officer Maurice Quintal
was promoted to Captain, in 1989
610
00:45:02,787 --> 00:45:06,763
Captain Bob Pearson went on to fly 10 more years
for Air Canada
611
00:45:06,787 --> 00:45:10,935
his experience at Gimli shaping
the rest of his career as a commercial pilot
612
00:45:10,959 --> 00:45:17,029
This experience affected me mostly
by making me more relaxed as a pilot,
613
00:45:17,053 --> 00:45:22,537
giving me the feeling that as much as I trained
for all those years that:
614
00:45:22,561 --> 00:45:27,763
There is always that question about how
you are going to perform when the chips are down
615
00:45:27,788 --> 00:45:31,840
And now, I have the feeling that no matter what
as long as the aircraft stay together,
616
00:45:31,865 --> 00:45:33,958
we will get it safely back on the ground
617
00:45:34,443 --> 00:45:37,161
It is a relaxing experience
618
00:45:37,995 --> 00:45:42,693
It is the knowledge that you know:
under stress, you can perform
619
00:45:43,293 --> 00:45:45,293
before that, you don't know
620
00:45:45,317 --> 00:45:48,887
You just hope you will
and you train for it...
621
00:45:48,911 --> 00:45:50,512
...but you never know
622
00:45:50,536 --> 00:45:54,879
With the things that they had to deal with
was magnificent
623
00:45:54,903 --> 00:45:59,028
I think that it got proven
in the simulator of Vancouver
624
00:45:59,052 --> 00:46:04,223
They tried out the same circumstances
with several crews...
625
00:46:04,247 --> 00:46:06,247
...and they all crashed
626
00:46:06,692 --> 00:46:11,146
Probably, the most important thing that came out
of it is the realization that
627
00:46:11,170 --> 00:46:14,442
when something new is introduced
628
00:46:14,466 --> 00:46:19,622
special attention and training
needs to be accomplished
629
00:46:19,646 --> 00:46:22,411
for people, to be aware,
what they are dealing with
630
00:46:22,435 --> 00:46:26,106
When we had landed
and the air-plane was all in one piece
631
00:46:26,130 --> 00:46:30,497
I thought:
Wow, I got another chance and to fly again
632
00:46:30,521 --> 00:46:31,849
Because of a tragic like that,
633
00:46:31,874 --> 00:46:34,529
you want to take your deck of
cards and fire it in the air
634
00:46:34,553 --> 00:46:36,169
You are truly free
635
00:46:36,193 --> 00:46:40,802
I guess from that point of view
I find it very difficult to say, but
636
00:46:40,827 --> 00:46:44,013
Gimli was maybe almost
the best thing that ever happened to me,
637
00:46:44,037 --> 00:46:47,108
next to meeting my wonderful wife
and marrying her
638
00:46:48,217 --> 00:46:50,412
Two days after the landing at Gimli...
639
00:46:50,436 --> 00:46:56,435
...Air Canada's 767 was back in the air
on its way to Winnipeg for repairs
640
00:46:57,185 --> 00:47:01,435
A quarter century later,
that same plane is still in service
641
00:47:01,459 --> 00:47:05,115
and it still carries the nickname
that Bob Pearson earned it:
642
00:47:05,139 --> 00:47:07,139
The Gimli Glider
643
00:47:07,163 --> 00:47:11,311
