1
00:00:01,027 --> 00:00:02,592
Three, two, one, now.
2
00:00:04,787 --> 00:00:06,352
Concorde.
3
00:00:06,387 --> 00:00:09,632
The world's most advanced
passenger aircraft.
4
00:00:09,667 --> 00:00:11,592
It took civil aviation
5
00:00:11,667 --> 00:00:14,752
from 10 miles a minute
to 23 miles a minute
6
00:00:14,787 --> 00:00:17,079
in one single stride.
7
00:00:18,667 --> 00:00:20,639
Going up to
mach one, mach one.
8
00:00:20,674 --> 00:00:22,912
A
technological masterpiece
9
00:00:22,947 --> 00:00:25,439
that could travel at
twice the speed of sound.
10
00:00:27,234 --> 00:00:30,672
It is just the
most perfect shape.
11
00:00:30,707 --> 00:00:32,439
It's just beautiful to look at.
12
00:00:33,307 --> 00:00:36,672
Then, 24
years into an flawless run,
13
00:00:36,707 --> 00:00:38,952
the unthinkable happens.
14
00:00:44,434 --> 00:00:46,999
Concorde had
an achilles heel.
15
00:00:47,074 --> 00:00:48,072
Le bourget, le bourget.
16
00:00:48,147 --> 00:00:49,592
We are trying to for le bourget.
17
00:00:49,667 --> 00:00:51,879
Then there was
this huge explosion.
18
00:00:52,947 --> 00:00:55,152
And I was totally
engulfed in flame.
19
00:00:55,161 --> 00:00:59,319
It's an accident
that should never have happened.
20
00:01:22,467 --> 00:01:24,992
July 25th, 2000,
21
00:01:25,027 --> 00:01:28,192
was gearing up to be a
typically hectic summer's day
22
00:01:28,227 --> 00:01:30,719
at Paris' Charles
de gaulle airport.
23
00:01:35,107 --> 00:01:37,552
The holiday season
was in full swing.
24
00:01:37,587 --> 00:01:39,159
And to add to the pressure,
25
00:01:39,234 --> 00:01:42,712
the French president
Jacques chirac was flying in
26
00:01:42,787 --> 00:01:44,839
from an international
summit in Tokyo.
27
00:01:53,187 --> 00:01:55,592
It would have been a
very busy scene that day.
28
00:01:55,667 --> 00:01:57,399
I mean, it was high summer.
29
00:01:57,474 --> 00:02:00,592
There would have been plenty
of planes arriving, taking off,
30
00:02:00,667 --> 00:02:03,239
and holiday makers arriving,
holiday makers leaving.
31
00:02:03,314 --> 00:02:07,272
It was a classic, busy
airport in high summer.
32
00:02:07,347 --> 00:02:09,232
On duty
in the southern tower
33
00:02:09,267 --> 00:02:12,592
was air traffic
controller gilles logelin.
34
00:02:12,627 --> 00:02:14,592
I was not supposed
to work that day,
35
00:02:14,627 --> 00:02:17,952
but just the day before
a colleague asked me
36
00:02:18,027 --> 00:02:20,472
if I could take his shift.
37
00:02:20,547 --> 00:02:23,872
And the result of this
was that I was due to work
38
00:02:23,907 --> 00:02:25,639
at the southern control tower.
39
00:02:26,381 --> 00:02:29,312
Five miles
west of Charles de gaulle
40
00:02:29,347 --> 00:02:31,392
was the small town of gonesse
41
00:02:31,427 --> 00:02:34,919
that catered to people traveling
to and from the airport.
42
00:02:37,507 --> 00:02:38,992
Gonesse is a name
that would have meant nothing
43
00:02:39,027 --> 00:02:40,472
to anybody really in France.
44
00:02:40,547 --> 00:02:42,679
It's really the
edge of the city,
45
00:02:42,754 --> 00:02:44,312
it's where city meets field,
46
00:02:44,387 --> 00:02:46,992
and it really literally does.
47
00:02:47,027 --> 00:02:50,512
It's a strange one, no one
stays there for very long.
48
00:02:50,547 --> 00:02:54,192
It just feels a bit
empty, transient.
49
00:02:54,227 --> 00:02:55,599
It's an odd place.
50
00:03:04,227 --> 00:03:06,352
It was a very
hot summer's day
51
00:03:06,427 --> 00:03:09,312
and I had just arrived
into this hotel
52
00:03:09,347 --> 00:03:10,992
because I was
meant to be meeting
53
00:03:11,027 --> 00:03:13,392
a youth orchestra from the UK
54
00:03:13,427 --> 00:03:16,032
and I was gonna be their
concert tour manager,
55
00:03:16,067 --> 00:03:18,559
and I was looking forward to
a really good week with them.
56
00:03:20,147 --> 00:03:21,592
When I got there, I
did think to myself,
57
00:03:21,667 --> 00:03:24,519
this this is more the
budget end of hotels
58
00:03:24,594 --> 00:03:26,592
rather than a luxurious hotel.
59
00:03:26,667 --> 00:03:27,872
The walls were quite thin,
60
00:03:27,947 --> 00:03:29,792
there was hardly
any soundproofing,
61
00:03:29,827 --> 00:03:33,232
and because we were
just by a motorway
62
00:03:33,267 --> 00:03:35,792
and the airport was behind US,
63
00:03:35,827 --> 00:03:37,552
I was worried whether
it was going to be
64
00:03:37,587 --> 00:03:39,599
a comfortable stay
for the guests.
65
00:03:40,434 --> 00:03:44,032
I had some time to spare so
I thought about having a nap,
66
00:03:44,067 --> 00:03:46,592
and in the end I decided
to phone my sister
67
00:03:46,667 --> 00:03:48,752
who was in London at the time.
68
00:03:51,074 --> 00:03:53,152
Flying to
New York that afternoon
69
00:03:53,161 --> 00:03:56,592
was the most famous commercial
airplane in the world.
70
00:03:56,627 --> 00:03:57,639
Concorde.
71
00:03:59,507 --> 00:04:01,792
On board the air France
flight that day to New York
72
00:04:01,801 --> 00:04:03,239
were 100 passengers,
73
00:04:03,927 --> 00:04:08,272
and most of them were
related or friends,
74
00:04:08,347 --> 00:04:10,592
and all from the
same German town.
75
00:04:10,667 --> 00:04:12,952
These are people that,
you know, had saved up
76
00:04:13,027 --> 00:04:16,672
and longed to
travel by concorde.
77
00:04:16,707 --> 00:04:17,799
The
charter passengers
78
00:04:17,874 --> 00:04:18,832
couldn't wait to tell you
79
00:04:18,867 --> 00:04:20,359
it was their first trip,
80
00:04:20,434 --> 00:04:23,159
they couldn't wait to tell
you that they'd saved up
81
00:04:23,234 --> 00:04:25,272
to do this exciting trip,
82
00:04:25,347 --> 00:04:28,032
and it was something
they'd always wanted to do.
83
00:04:28,067 --> 00:04:31,952
They were on an aircraft that
had an amazing safety record,
84
00:04:31,987 --> 00:04:34,792
and I'm sure it never
even crossed their minds
85
00:04:34,867 --> 00:04:38,039
for one minute that
anything could go wrong.
86
00:04:39,987 --> 00:04:41,392
On concorde,
87
00:04:41,427 --> 00:04:44,192
the passengers knew
they were in good hands.
88
00:04:44,227 --> 00:04:47,552
Concorde's pilots
were an elite,
89
00:04:47,627 --> 00:04:49,392
there's no question about that.
90
00:04:49,427 --> 00:04:50,752
They had to be.
91
00:04:50,827 --> 00:04:52,519
Concorde did everything
much more quickly
92
00:04:52,594 --> 00:04:54,199
than a normal aircraft
93
00:04:54,274 --> 00:04:56,992
so you need to have that
slight fighter pilot mentality.
94
00:04:57,027 --> 00:04:59,472
Piloting flight 4590
95
00:04:59,481 --> 00:05:02,399
was 54-year-old Christian Marty.
96
00:05:03,827 --> 00:05:06,999
Marty had over
13,000 flying hours
97
00:05:07,074 --> 00:05:10,239
and had once successfully
wind-surfed across the Atlantic.
98
00:05:14,434 --> 00:05:16,352
At 4:34 P.M.,
99
00:05:16,361 --> 00:05:19,592
captain Marty taxied concorde
out to the holding point
100
00:05:19,667 --> 00:05:21,519
for runway 26 right.
101
00:05:22,627 --> 00:05:25,952
Air France 4590,
good day.
102
00:05:25,987 --> 00:05:29,119
Taxi to holding point
26 right via Romeo.
103
00:05:31,827 --> 00:05:33,472
Just
eight minutes later,
104
00:05:33,507 --> 00:05:37,399
flight 4590 was given
clearance for takeoff.
105
00:05:38,434 --> 00:05:41,632
Flight 4590,
runway 26 right.
106
00:05:41,667 --> 00:05:43,439
Wind 098 knots.
107
00:05:45,827 --> 00:05:48,032
In less
than 3 1/2 hours,
108
00:05:48,067 --> 00:05:50,559
concorde was due to
touch down in New York.
109
00:05:51,747 --> 00:05:53,632
Prepare for takeoff.
110
00:05:53,707 --> 00:05:55,472
Is everybody ready?
111
00:05:55,507 --> 00:05:57,479
Three, two, one, now.
112
00:06:01,827 --> 00:06:03,232
But this time,
113
00:06:03,267 --> 00:06:06,592
the experience would
be entirely different.
114
00:06:06,627 --> 00:06:09,952
The aircraft was
gaining power as usual,
115
00:06:09,961 --> 00:06:13,472
and then all of a sudden I
saw something incredible.
116
00:06:13,481 --> 00:06:15,592
I saw a flame behind the plane.
117
00:06:15,667 --> 00:06:19,232
I immediately informed
the pilot by radio
118
00:06:19,267 --> 00:06:22,192
that there were flames
behind the aircraft.
119
00:06:22,227 --> 00:06:27,392
4590, you have flames,
you have flames behind you.
120
00:06:27,427 --> 00:06:28,992
And at the same
time I was talking
121
00:06:29,027 --> 00:06:32,912
I still remember I pushed
the red alert button.
122
00:06:38,827 --> 00:06:40,359
But what I knew
is that the plane
123
00:06:40,434 --> 00:06:42,672
will have to
continue the takeoff.
124
00:06:42,707 --> 00:06:45,072
Concorde
had passed v1,
125
00:06:45,107 --> 00:06:48,632
the first critical
speed of any takeoff.
126
00:06:48,707 --> 00:06:52,999
If you have a
problem of some sort after v1,
127
00:06:54,627 --> 00:06:58,672
you are now committed to taking
that airplane into the air.
128
00:06:58,681 --> 00:07:03,639
There is not sufficient
length of runway left
129
00:07:03,714 --> 00:07:06,192
for you to guarantee
that you can stop safely
130
00:07:06,227 --> 00:07:07,872
within the remaining length.
131
00:07:07,907 --> 00:07:09,352
Seconds later,
132
00:07:09,427 --> 00:07:12,752
gille logelin contacts
captain Marty again.
133
00:07:12,787 --> 00:07:14,272
It's really burning,
134
00:07:14,347 --> 00:07:16,992
and I'm not sure it's
coming from the engine.
135
00:07:17,027 --> 00:07:19,752
The flames looks bigger
than at the beginning
136
00:07:19,827 --> 00:07:23,192
so I give another second
information to the crew.
137
00:07:23,267 --> 00:07:25,392
Every split second was important
138
00:07:25,427 --> 00:07:28,672
because I knew that I wanted
to clear the air space
139
00:07:28,707 --> 00:07:31,392
to enable the crew
of the concorde
140
00:07:31,427 --> 00:07:33,639
to do whatever they wanted to do
141
00:07:33,714 --> 00:07:34,999
to solve the problem.
142
00:07:35,714 --> 00:07:38,192
Are you shutting
down engine two there?
143
00:07:38,227 --> 00:07:39,319
I shut it down.
144
00:07:40,347 --> 00:07:41,392
Le bourget, le bourget.
145
00:07:41,427 --> 00:07:43,799
We are trying for le bourget.
146
00:07:43,874 --> 00:07:46,912
What I remember very
well is the beating of my heart,
147
00:07:46,987 --> 00:07:48,272
it was terrible.
148
00:07:48,347 --> 00:07:50,119
I never experienced that before.
149
00:07:52,107 --> 00:07:53,552
Despite the fire,
150
00:07:53,587 --> 00:07:56,792
captain Marty attempts
to gain altitude.
151
00:07:56,867 --> 00:08:00,199
So I was very busy
giving order to other aircraft.
152
00:08:00,274 --> 00:08:03,232
At the moment, I didn't
watch the concorde
153
00:08:03,307 --> 00:08:04,952
for a split second.
154
00:08:05,027 --> 00:08:09,639
And I just saw kind of like
a big mushroom of smoke
155
00:08:09,714 --> 00:08:10,879
coming from the ground.
156
00:08:12,227 --> 00:08:14,192
Just two
minutes and seven seconds
157
00:08:14,227 --> 00:08:16,679
from the start of
its takeoff run,
158
00:08:16,754 --> 00:08:20,159
flight 4590 falls
out of the sky,
159
00:08:21,187 --> 00:08:23,639
hitting a hotel outside gonesse.
160
00:08:25,827 --> 00:08:27,552
So I'm on the
phone to my sister,
161
00:08:27,587 --> 00:08:29,952
just having a routine
chat about things,
162
00:08:29,961 --> 00:08:33,672
and then there was
this huge explosion.
163
00:08:33,681 --> 00:08:37,312
I remember turning around
after the phone line went dead
164
00:08:37,347 --> 00:08:41,392
and seeing the walls of
my hotel room caving in
165
00:08:41,427 --> 00:08:44,032
and the pictures coming
down from the wall.
166
00:08:44,067 --> 00:08:45,872
As soon as I opened
the door, of course,
167
00:08:45,907 --> 00:08:48,032
I was totally engulfed in flame.
168
00:08:48,067 --> 00:08:51,632
The heat was phenomenal.
169
00:08:51,667 --> 00:08:56,192
It's hard to describe what it
was like being in that oven.
170
00:08:56,227 --> 00:08:59,799
That was the moment where
171
00:08:59,874 --> 00:09:02,352
literally my life
flashed before my eyes.
172
00:09:02,361 --> 00:09:03,879
I knew I had to get
out of there,
173
00:09:03,954 --> 00:09:05,552
I knew I was about to die,
174
00:09:05,561 --> 00:09:08,159
and so you just do what
has to be done at the time.
175
00:09:11,794 --> 00:09:16,032
I had a matter of split
seconds to just open the window
176
00:09:16,067 --> 00:09:17,552
and jump out.
177
00:09:17,587 --> 00:09:19,552
I remember thinking,
178
00:09:19,587 --> 00:09:22,792
I have to stop breathing
now, I have to stop inhaling,
179
00:09:22,867 --> 00:09:25,112
because it was toxic,
180
00:09:25,187 --> 00:09:28,512
it was this black thick smoke.
181
00:09:28,547 --> 00:09:30,519
I lowered myself down,
182
00:09:30,594 --> 00:09:32,432
and then, obviously,
didn't have quite as far
183
00:09:32,467 --> 00:09:34,592
to drop down to the ground,
184
00:09:34,627 --> 00:09:35,999
and then just ran, ran, ran.
185
00:09:39,987 --> 00:09:42,152
Four
others inside the hotel
186
00:09:42,227 --> 00:09:43,719
were killed instantly.
187
00:09:46,187 --> 00:09:49,479
Air France
4590, do you hear me?
188
00:09:50,627 --> 00:09:54,672
Air France 4590, do you hear me?
189
00:09:54,707 --> 00:09:58,352
I call twice and
ask air France 4590,
190
00:09:58,387 --> 00:10:00,112
do you hear me?
191
00:10:00,147 --> 00:10:03,519
I had no answer and then I
realize it was the end, yeah.
192
00:10:07,161 --> 00:10:09,199
I just sat down on
the carpet and cried.
193
00:10:20,147 --> 00:10:22,032
I can't imagine what it
was like on the airplane
194
00:10:22,067 --> 00:10:23,599
for the passengers or the crew.
195
00:10:24,381 --> 00:10:29,479
Horrible, terrible,
frightening, terrifying.
196
00:10:34,627 --> 00:10:37,072
On July 25th, 2000,
197
00:10:37,107 --> 00:10:40,072
100 passengers and
nine crew members
198
00:10:40,147 --> 00:10:43,479
on board the concorde all died.
199
00:10:44,627 --> 00:10:46,512
How could the most
thoroughly tested
200
00:10:46,547 --> 00:10:48,272
commercial plane in history
201
00:10:48,307 --> 00:10:50,719
undergo such a
catastrophic failure?
202
00:10:51,947 --> 00:10:54,999
And what, or who, was to blame?
203
00:10:58,881 --> 00:11:01,712
News caster: An air France
concorde has crashed near Paris,
204
00:11:01,747 --> 00:11:03,632
killing everybody on board.
205
00:11:10,227 --> 00:11:12,359
The picture
emerging at the moment
206
00:11:12,434 --> 00:11:15,552
is pointing clearly to the
malfunction of an engine
207
00:11:15,587 --> 00:11:17,072
and nothing else.
208
00:11:17,107 --> 00:11:20,472
It was the most
profound shock.
209
00:11:20,547 --> 00:11:23,112
It was something that
I'd always regarded
210
00:11:23,187 --> 00:11:25,112
as almost inconceivable.
211
00:11:25,187 --> 00:11:26,999
100 passengers
and all their baggage
212
00:11:27,074 --> 00:11:29,792
from London to new
York in three hours.
213
00:11:29,827 --> 00:11:31,272
That's the promise
of the concorde,
214
00:11:31,347 --> 00:11:33,712
the joint anglo-French
supersonic aircraft.
215
00:11:39,481 --> 00:11:42,192
Concorde
was a child of the 60s,
216
00:11:42,201 --> 00:11:44,912
a combination of British
and French engineering
217
00:11:44,947 --> 00:11:46,999
and technological brilliance.
218
00:11:49,027 --> 00:11:51,592
What's interesting is
that this most beautiful
219
00:11:51,601 --> 00:11:53,872
of all human-made artifacts,
220
00:11:53,907 --> 00:11:56,712
its shape, its form
is pure engineering.
221
00:11:56,787 --> 00:11:58,992
Every line on that machine
222
00:11:59,027 --> 00:12:03,632
is the result of precise
mathematics and engineering.
223
00:12:03,667 --> 00:12:07,112
There is no art with
a capital a involved.
224
00:12:07,121 --> 00:12:09,872
It's the art of aerodynamics.
225
00:12:11,187 --> 00:12:13,799
Now at maximum
speed, mach 2.2,
226
00:12:13,874 --> 00:12:15,472
slicing through the
air twice as fast
227
00:12:15,507 --> 00:12:16,719
as a bullet from a gun.
228
00:12:18,387 --> 00:12:23,072
Concorde took aviation
in one single giant stride
229
00:12:23,107 --> 00:12:26,152
from a pedestrian
600 miles an hour
230
00:12:26,227 --> 00:12:28,312
to 1,350 miles an hour.
231
00:12:28,387 --> 00:12:31,872
One great leap in
aviation history.
232
00:12:33,827 --> 00:12:35,872
Concorde
first took to the skies
233
00:12:35,907 --> 00:12:38,352
at the French testing
site in Toulouse
234
00:12:38,361 --> 00:12:41,039
on march 2nd, 1969.
235
00:12:42,681 --> 00:12:46,752
I will always
remember Raymond Baxter,
236
00:12:46,787 --> 00:12:49,952
his commentary on
that first takeoff.
237
00:12:49,961 --> 00:12:53,272
Baxter: Nose come up to
20 degrees, she's airborne.
238
00:12:56,547 --> 00:12:57,632
She flies.
239
00:12:57,667 --> 00:12:59,719
Concorde flies at last.
240
00:13:01,347 --> 00:13:02,472
Six weeks later,
241
00:13:02,547 --> 00:13:03,799
the maiden British flight
242
00:13:03,874 --> 00:13:06,279
departed from
filton, near Bristol.
243
00:13:07,961 --> 00:13:09,592
And she Rose.
244
00:13:09,667 --> 00:13:13,632
1969 was the most
extraordinary year
245
00:13:13,667 --> 00:13:17,632
in terms of great
aerospace achievements.
246
00:13:17,641 --> 00:13:20,672
All is going
well and she's airborne.
247
00:13:20,707 --> 00:13:22,272
That was the
year of the first
248
00:13:22,307 --> 00:13:25,432
flight of the boeing 747.
249
00:13:25,507 --> 00:13:29,159
It was the year of
the lunar landings.
250
00:13:29,234 --> 00:13:33,392
And it was the year of
concorde's first flight.
251
00:13:33,467 --> 00:13:35,159
Climbing at
4,000 feet a minute.
252
00:13:35,234 --> 00:13:39,639
Just look at the beautiful lines
of that slender delta wing.
253
00:13:41,747 --> 00:13:44,559
Climbing steeply
into the sunlit sky.
254
00:13:47,347 --> 00:13:48,832
By
the new millennium,
255
00:13:48,867 --> 00:13:50,519
concorde had
thousands of flights
256
00:13:50,594 --> 00:13:52,599
under its elegant delta wings.
257
00:13:53,267 --> 00:13:56,152
Extremely fine view
of the curvature of the earth
258
00:13:56,227 --> 00:13:58,632
that we have up here today.
259
00:13:58,707 --> 00:14:01,519
It was the world's
fastest passenger plane.
260
00:14:02,787 --> 00:14:05,279
And regarded as
one of the safest.
261
00:14:11,907 --> 00:14:14,272
I was working at
the French news agency
262
00:14:14,307 --> 00:14:15,832
agence France-presse,
263
00:14:15,907 --> 00:14:19,919
at which point I was
dispatched to the scene.
264
00:14:22,827 --> 00:14:26,112
A plane crash is always
terrible, always big news.
265
00:14:26,187 --> 00:14:27,479
The crash of concorde, though,
266
00:14:27,554 --> 00:14:29,872
is in a different
league altogether.
267
00:14:31,394 --> 00:14:32,879
And after a certain
point I got off the taxi
268
00:14:32,914 --> 00:14:35,952
and then hoofed
it across fields,
269
00:14:35,987 --> 00:14:40,119
and I suddenly found
myself milling around
270
00:14:40,787 --> 00:14:45,359
at the operation center for
the emergency operation.
271
00:14:47,874 --> 00:14:50,472
I'm left wondering
what I'm looking at.
272
00:14:50,547 --> 00:14:53,312
I mean, there's no
sign of a fuselage
273
00:14:53,347 --> 00:14:56,032
or the carcass of an aircraft.
274
00:14:56,067 --> 00:15:01,272
What I did see were sort
of furrows in the ground,
275
00:15:01,347 --> 00:15:05,552
and then the most striking
image which stays with me now,
276
00:15:05,587 --> 00:15:09,712
these traffic cones
dotted around this field,
277
00:15:09,747 --> 00:15:12,272
and then realizing
what they were
278
00:15:12,307 --> 00:15:15,952
which is they were marking
bodies or parts of bodies.
279
00:15:15,987 --> 00:15:19,552
But I felt much more closely
280
00:15:19,587 --> 00:15:22,072
the human horror of all of this.
281
00:15:22,147 --> 00:15:26,072
And when I reflected afterwards
on those traffic cones
282
00:15:26,147 --> 00:15:29,072
being used as markers
for the bodies
283
00:15:29,107 --> 00:15:32,272
and the sort of pithiness of it,
284
00:15:32,307 --> 00:15:34,039
the horror of it came through.
285
00:15:38,521 --> 00:15:40,519
After
the crash of concorde,
286
00:15:40,594 --> 00:15:44,152
air France immediately
grounded its entire fleet.
287
00:15:44,227 --> 00:15:47,239
French and British investigators
were called to the scene.
288
00:15:48,467 --> 00:15:49,479
The phone rang,
289
00:15:50,467 --> 00:15:53,392
and it was the duty coordinator.
290
00:15:53,427 --> 00:15:54,952
He said, "it's the concorde."
291
00:15:55,027 --> 00:15:56,832
And he said its crashed
into a hotel in Paris,
292
00:15:56,867 --> 00:15:58,352
there are fatalities
on the ground,
293
00:15:58,361 --> 00:16:00,239
everybody in the
aircraft is dead.
294
00:16:01,827 --> 00:16:06,152
And it was the start
of quite an intense
295
00:16:06,227 --> 00:16:09,199
emotional as well technical
and workload period.
296
00:16:10,627 --> 00:16:12,272
Within hours,
297
00:16:12,307 --> 00:16:15,992
the British investigation
team was heading to Paris.
298
00:16:16,067 --> 00:16:18,752
Our business is
very evidence driven
299
00:16:18,827 --> 00:16:22,672
and it's important to try
to get to an accident site
300
00:16:22,707 --> 00:16:24,592
as soon as you practically can
301
00:16:24,667 --> 00:16:26,632
because the quality of
evidence at that site
302
00:16:26,707 --> 00:16:28,359
is not going to
improve with time,
303
00:16:28,434 --> 00:16:29,919
it's going to decay with time.
304
00:16:31,987 --> 00:16:34,792
France's bureau
d'enquetes took the lead
305
00:16:34,867 --> 00:16:36,312
with assistance from britain's
306
00:16:36,387 --> 00:16:38,359
air accident
investigation board.
307
00:16:40,627 --> 00:16:42,992
I got to the accident
site the following morning
308
00:16:43,027 --> 00:16:45,479
in company with our French
investigator colleagues
309
00:16:45,554 --> 00:16:47,312
from the bureau d'enquetes.
310
00:16:47,347 --> 00:16:49,319
It wasn't a huge accident site,
311
00:16:49,394 --> 00:16:52,912
but within that perimeter it
was just total devastation.
312
00:16:52,947 --> 00:16:54,832
It was one of the
most devastated sites
313
00:16:54,867 --> 00:16:56,039
I think I've ever seen.
314
00:16:59,027 --> 00:17:01,752
The team started
by examining the wreckage
315
00:17:01,827 --> 00:17:03,352
and looking through photographs
316
00:17:03,427 --> 00:17:05,792
of the plane's final moments.
317
00:17:05,827 --> 00:17:07,312
Absolutely vital.
318
00:17:07,347 --> 00:17:09,792
Photographs, as the
saying goes, don't lie.
319
00:17:09,801 --> 00:17:11,792
The picture that
really caught our eye
320
00:17:11,827 --> 00:17:13,232
right from the beginning
321
00:17:13,267 --> 00:17:15,472
was the picture that
is seen from head on
322
00:17:15,507 --> 00:17:16,912
with the aircraft, concorde,
323
00:17:16,947 --> 00:17:19,479
heading towards you
with the flames.
324
00:17:19,554 --> 00:17:21,152
I think we all
thought initially
325
00:17:21,187 --> 00:17:23,392
that it was an engine fire,
326
00:17:23,427 --> 00:17:27,959
and it was only some time into
the accident, hours, days,
327
00:17:28,034 --> 00:17:30,192
that we started to
seriously wonder
328
00:17:30,227 --> 00:17:33,272
if the fire had been
inboard of the engine,
329
00:17:33,347 --> 00:17:36,952
based on the very fuzzy
photographs that we had
330
00:17:37,027 --> 00:17:40,359
which seemed to show the
fuel coming out of the wing
331
00:17:40,434 --> 00:17:42,999
and the fire inboard
of the engines.
332
00:17:47,767 --> 00:17:50,352
Concorde had an
elaborate array of fuel tanks
333
00:17:50,387 --> 00:17:53,039
in both wings and
parts of the fuselage.
334
00:17:55,347 --> 00:17:56,912
Investigators soon discovered
335
00:17:56,947 --> 00:17:59,272
a piece of wreckage
from one of the tanks
336
00:17:59,347 --> 00:18:01,559
that could be the
source of the fuel leak.
337
00:18:04,521 --> 00:18:09,032
The piece of tank
was completely unburnt.
338
00:18:09,107 --> 00:18:10,512
It was clearly fuel tank
339
00:18:10,547 --> 00:18:13,312
because it had the
sealant from fuel tanks
340
00:18:13,347 --> 00:18:15,152
on the inside face.
341
00:18:15,187 --> 00:18:19,072
But the paint on it was totally
unmarked by any heat damage.
342
00:18:19,147 --> 00:18:21,679
So we were pretty sure
it was lower-wing skin.
343
00:18:22,754 --> 00:18:24,072
They
eventually discovered
344
00:18:24,147 --> 00:18:26,472
that it came from
fuel tank number five,
345
00:18:26,547 --> 00:18:29,199
in front of the left-hand
undercarriage bay.
346
00:18:30,827 --> 00:18:32,519
It really began
to seem to US
347
00:18:32,594 --> 00:18:34,839
that it had to be a
ruptured fuel tank
348
00:18:34,914 --> 00:18:36,992
that was releasing the fuel.
349
00:18:37,027 --> 00:18:39,319
And so the question to US came,
350
00:18:39,394 --> 00:18:42,192
well, how on earth
does that get ruptured?
351
00:18:42,201 --> 00:18:44,152
A particular
feature of concorde
352
00:18:44,227 --> 00:18:47,552
is that it's a delta wing.
353
00:18:47,587 --> 00:18:50,832
And what that means is that
the distance on the wing
354
00:18:50,841 --> 00:18:53,232
between the front of the
wing and the back of the wing
355
00:18:53,267 --> 00:18:57,952
is very long compared to a
conventional configuration.
356
00:18:57,987 --> 00:19:00,679
So the wing skins can
be very, very thin,
357
00:19:00,754 --> 00:19:02,792
just a few millimeters,
358
00:19:02,867 --> 00:19:06,272
compared to probably an inch
thick down at the wing root
359
00:19:06,307 --> 00:19:08,279
on a conventional aircraft.
360
00:19:09,347 --> 00:19:11,152
If
struck hard enough,
361
00:19:11,161 --> 00:19:13,472
the delta wing was vulnerable.
362
00:19:13,507 --> 00:19:14,839
But what could have hit it?
363
00:19:15,507 --> 00:19:18,359
The team turned their
attention to the runway.
364
00:19:20,627 --> 00:19:23,552
Material that was found
along the runway was crucial
365
00:19:23,587 --> 00:19:26,592
as that was really the
source of this accident
366
00:19:26,627 --> 00:19:31,072
and gave you a timeline between
the initiation of the event
367
00:19:31,147 --> 00:19:32,839
all the way through
to when the aircraft
368
00:19:32,914 --> 00:19:34,039
has left the ground.
369
00:19:35,827 --> 00:19:38,832
On the runway we
found a piece of tire,
370
00:19:38,867 --> 00:19:40,672
a very large piece of tire,
371
00:19:40,707 --> 00:19:42,952
which was completely unburnt,
372
00:19:43,027 --> 00:19:45,392
so it had obviously been
released from the aircraft
373
00:19:45,427 --> 00:19:46,719
at a very early stage.
374
00:19:47,427 --> 00:19:49,472
Throughout
its years of service,
375
00:19:49,481 --> 00:19:52,959
concorde had suffered a
total of 57 tire failures.
376
00:19:54,147 --> 00:19:55,792
Looking through
the records,
377
00:19:55,827 --> 00:19:58,912
there had been a number
of previous cases
378
00:19:58,947 --> 00:20:02,512
where concorde main tires
379
00:20:02,547 --> 00:20:05,639
had lost tread or ruptured
380
00:20:06,454 --> 00:20:09,752
and caused a certain
amount of damage,
381
00:20:09,827 --> 00:20:14,159
including where fuel
tanks had been penetrated.
382
00:20:14,914 --> 00:20:18,032
But what the Charles de
gaulle accident showed
383
00:20:18,067 --> 00:20:19,632
was the previous cases
384
00:20:19,667 --> 00:20:23,152
really hadn't been
properly addressed.
385
00:20:23,187 --> 00:20:25,799
The concorde tires
had been subjected
386
00:20:25,874 --> 00:20:29,472
to much higher
stress because, a,
387
00:20:29,481 --> 00:20:33,159
they're on the runway going
up to much higher speeds.
388
00:20:33,234 --> 00:20:36,472
In concords case, up
to around 200 knots
389
00:20:36,547 --> 00:20:38,912
before the airplane lifts off.
390
00:20:38,987 --> 00:20:41,872
And secondly because
the delta wing
391
00:20:41,907 --> 00:20:45,392
doesn't generate
any lift in concorde
392
00:20:45,427 --> 00:20:47,592
until you actually
present that wing
393
00:20:47,667 --> 00:20:49,039
at an angle to the air flow.
394
00:20:53,747 --> 00:20:55,639
The investigation
team now believed
395
00:20:55,714 --> 00:20:57,432
it was a tire failure
396
00:20:57,507 --> 00:21:00,199
that had fired a large piece
of rubber into a fuel tank,
397
00:21:01,107 --> 00:21:04,039
causing a massive fuel release.
398
00:21:06,227 --> 00:21:09,552
I think it was pretty
obvious that a tire had burst,
399
00:21:09,587 --> 00:21:13,639
and from the nature of
the the damage to the tire
400
00:21:13,714 --> 00:21:16,439
we started to form theories
as to what had happened.
401
00:21:17,094 --> 00:21:18,832
Besides
the usual shredding
402
00:21:18,867 --> 00:21:21,152
typical of a tire blowout,
403
00:21:21,161 --> 00:21:23,952
the debris revealed a clean cut.
404
00:21:23,961 --> 00:21:26,752
The tire was cut from
shoulder to shoulder
405
00:21:26,787 --> 00:21:28,672
through the entire
depth of the tire.
406
00:21:28,707 --> 00:21:31,432
Now that just was not
a normal tire blowout,
407
00:21:31,507 --> 00:21:33,152
it looked like the
tire had been sliced
408
00:21:33,187 --> 00:21:34,912
from corner to corner.
409
00:21:34,987 --> 00:21:39,752
And it was possible
fairly rapidly to match that up
410
00:21:39,827 --> 00:21:41,719
with a similar clean cut
411
00:21:42,454 --> 00:21:45,312
on the remains of
the number two tire
412
00:21:45,321 --> 00:21:49,312
which was still on the number
two main landing gear wheel
413
00:21:49,321 --> 00:21:50,639
at the crash site.
414
00:21:53,234 --> 00:21:55,479
Concorde had
two main landing gears
415
00:21:55,554 --> 00:21:57,199
under the right and left wings.
416
00:21:58,707 --> 00:22:02,159
Each was made of a bogie
beam carrying four wheels.
417
00:22:03,627 --> 00:22:06,352
Number two tire was on
the front inner wheel
418
00:22:06,387 --> 00:22:07,959
on the left-hand beam.
419
00:22:09,427 --> 00:22:10,992
So the question
then was, well,
420
00:22:11,001 --> 00:22:14,439
what could have caused
that clean cut in the tire?
421
00:22:15,074 --> 00:22:16,912
On the
same part of the runway
422
00:22:16,947 --> 00:22:18,512
as the tire debris,
423
00:22:18,547 --> 00:22:20,312
they discovered a clue
424
00:22:20,387 --> 00:22:23,392
that would change the
course of the investigation.
425
00:22:23,427 --> 00:22:26,472
It was a metal strip
about an inch wide,
426
00:22:26,547 --> 00:22:27,752
made of titanium,
427
00:22:27,827 --> 00:22:29,879
about a bit longer than a ruler,
428
00:22:30,701 --> 00:22:35,872
and it was treated with
aerospace quality materials.
429
00:22:35,907 --> 00:22:38,992
It had rivets in it,
it had chromate primer,
430
00:22:39,027 --> 00:22:40,952
and high temperature
sealant on it.
431
00:22:41,027 --> 00:22:42,432
Not the sort of things
432
00:22:42,467 --> 00:22:44,752
that you would normally
get just anywhere.
433
00:22:44,827 --> 00:22:47,792
So we were sure it
was from an aircraft,
434
00:22:47,827 --> 00:22:50,792
but it didn't look
very well made.
435
00:22:50,867 --> 00:22:53,359
It almost looked like
something from a tractor.
436
00:22:54,867 --> 00:22:57,472
It was immediately
clear that this metal strip
437
00:22:57,507 --> 00:22:59,799
had to be the cause
of the tire blowout.
438
00:23:01,907 --> 00:23:04,752
The shape of the strip
married very closely
439
00:23:04,787 --> 00:23:08,359
to the cut between the two
pieces of tire that we had.
440
00:23:08,434 --> 00:23:11,232
It was quite eerie
because it did not look
441
00:23:11,267 --> 00:23:13,399
as if it could have
been just coincidence.
442
00:23:14,034 --> 00:23:16,832
But how could this
insignificant strip of metal
443
00:23:16,867 --> 00:23:18,192
bring down the world's
444
00:23:18,201 --> 00:23:20,119
most sophisticated
commercial airliner?
445
00:23:20,807 --> 00:23:23,479
If you drove your mini
over this piece of metal
446
00:23:23,554 --> 00:23:25,632
you wouldn't expect
it to burst the tire.
447
00:23:25,667 --> 00:23:29,479
The theory ended up being,
and validated in testing,
448
00:23:29,554 --> 00:23:30,952
was that the piece of metal
449
00:23:31,027 --> 00:23:33,152
had laid on the
runway on its edge,
450
00:23:33,187 --> 00:23:37,319
and the tire had approached
it at just the right attitude
451
00:23:38,627 --> 00:23:41,392
so that instead of
collapsing under the tire
452
00:23:41,427 --> 00:23:46,032
it stayed on its edge and
penetrated deep into the tire.
453
00:23:46,067 --> 00:23:47,479
It was almost inconceivable.
454
00:23:47,554 --> 00:23:49,279
We had trouble believing it.
455
00:23:51,427 --> 00:23:53,392
This was a
real breakthrough,
456
00:23:53,427 --> 00:23:55,479
and I think everyone
in the room,
457
00:23:55,554 --> 00:23:58,792
the bureau d'enquetes
folk, US aib,
458
00:23:58,801 --> 00:24:00,992
we all sensed that
at the same time,
459
00:24:01,027 --> 00:24:02,912
that suddenly we had a mechanism
460
00:24:02,947 --> 00:24:05,559
that could result in that
sort of release of fuel.
461
00:24:06,707 --> 00:24:08,199
It
was another chapter
462
00:24:08,274 --> 00:24:11,639
in a story of cooperation
between age-old rivals.
463
00:24:14,547 --> 00:24:15,872
The engineers,
464
00:24:15,907 --> 00:24:16,992
the French and the
British engineers,
465
00:24:17,027 --> 00:24:18,992
learned to get on very well.
466
00:24:19,001 --> 00:24:21,432
Now remember, at the time,
467
00:24:21,507 --> 00:24:23,392
many of them didn't
speak the same language,
468
00:24:23,427 --> 00:24:25,592
so that was a problem.
469
00:24:25,667 --> 00:24:28,672
British engineers thought
in imperial measurements,
470
00:24:28,707 --> 00:24:31,752
French engineers thought
in metric measurements.
471
00:24:31,827 --> 00:24:32,912
So there were these big gaps,
472
00:24:32,947 --> 00:24:35,272
but what they shared, of course,
473
00:24:35,347 --> 00:24:38,359
was a love of flight,
engineering, excitement,
474
00:24:38,434 --> 00:24:40,679
a project that
would pushed them,
475
00:24:40,754 --> 00:24:43,312
stretched them as far as
possible intellectually,
476
00:24:43,347 --> 00:24:44,912
practically, and so on.
477
00:24:44,947 --> 00:24:47,592
But there
were hitches along the way.
478
00:24:47,667 --> 00:24:49,432
The first was a disagreement
479
00:24:49,507 --> 00:24:52,519
over how concorde
should be spelled.
480
00:24:52,594 --> 00:24:55,072
Concorde is a lovely
French word, of course.
481
00:24:55,107 --> 00:24:57,792
It means fraternity,
it means togetherness.
482
00:24:57,827 --> 00:24:59,552
And concorde was going
to be a great meeting
483
00:24:59,587 --> 00:25:01,712
between the French
and the British.
484
00:25:01,787 --> 00:25:03,359
The British decided
485
00:25:03,394 --> 00:25:05,479
we can't be too French
about this, though.
486
00:25:05,554 --> 00:25:08,199
So concorde when we
write it won't have an e
487
00:25:08,274 --> 00:25:09,872
on the end of the word.
488
00:25:13,414 --> 00:25:15,152
16 of
the world's airlines
489
00:25:15,187 --> 00:25:17,159
on the threshold of
the supersonic age.
490
00:25:17,234 --> 00:25:19,992
Finally, when the
first prototype aircraft
491
00:25:20,067 --> 00:25:22,832
was put on display
in Toulouse in 1967,
492
00:25:22,867 --> 00:25:24,359
and Tony benn,
493
00:25:24,434 --> 00:25:26,472
who was the young minister
of technology then,
494
00:25:26,547 --> 00:25:28,352
just did away with
that nonsense.
495
00:25:28,387 --> 00:25:30,472
He said, "the aircraft
is called concorde,"
496
00:25:30,547 --> 00:25:32,512
he said, "with an e."
497
00:25:32,521 --> 00:25:35,712
And that meant excellence
and engineering
498
00:25:35,787 --> 00:25:37,472
and he also said englishness,
499
00:25:37,481 --> 00:25:38,832
which upset, of course,
500
00:25:38,841 --> 00:25:40,639
the Welsh, the Irish,
and the Scottish.
501
00:25:42,467 --> 00:25:43,992
Also, the politicians
502
00:25:44,001 --> 00:25:44,992
didn't trust each other
503
00:25:45,027 --> 00:25:46,279
over the finances.
504
00:25:46,947 --> 00:25:48,832
Concorde was
the key note in London,
505
00:25:48,841 --> 00:25:51,479
when britain's minister of
aviation Mr. Julian Avery
506
00:25:51,554 --> 00:25:53,472
and France's
ambassador to britain
507
00:25:53,507 --> 00:25:57,072
signed a joint agreement for
her development and production.
508
00:25:57,107 --> 00:25:59,392
A clause was
inserted into the contract
509
00:25:59,427 --> 00:26:01,592
stating that if one
side pulled out,
510
00:26:01,667 --> 00:26:02,839
the other could sue.
511
00:26:04,434 --> 00:26:08,512
With the development fee
estimated at 1.3 billion pounds,
512
00:26:08,547 --> 00:26:10,272
over seven billion today,
513
00:26:10,307 --> 00:26:12,352
neither side dared.
514
00:26:20,947 --> 00:26:26,999
But by July 2000, concorde
had also cost one 113 lives.
515
00:26:35,627 --> 00:26:40,359
As the investigation of concorde
flight 4590 moved forward,
516
00:26:40,434 --> 00:26:43,439
it established a possible
theory behind the crash.
517
00:26:44,167 --> 00:26:46,432
The joint French
and British team
518
00:26:46,467 --> 00:26:49,152
had discovered a metal
strip on the runway
519
00:26:49,187 --> 00:26:50,952
that almost certainly
had punctured
520
00:26:51,027 --> 00:26:52,999
one of the plane's tires.
521
00:26:53,074 --> 00:26:55,712
The blowout had
sent the tire debris
522
00:26:55,747 --> 00:26:57,479
crashing into a fuel tank,
523
00:26:57,554 --> 00:27:00,119
causing a leak and
a massive fire.
524
00:27:00,787 --> 00:27:05,159
The team now had to find out
where the strip had come from.
525
00:27:06,161 --> 00:27:08,032
The airport looked at
526
00:27:08,107 --> 00:27:11,152
the previous departures
from that runway,
527
00:27:11,187 --> 00:27:15,632
and one of those was a
continental airlines dc10.
528
00:27:15,667 --> 00:27:21,319
And colleagues in the US went
and examined the aircraft
529
00:27:22,307 --> 00:27:24,672
and discovered that a strip,
530
00:27:24,707 --> 00:27:27,319
a sealing strip for
the thrust reverser,
531
00:27:27,394 --> 00:27:31,639
was missing and the spacing
of the rivet holes matched up
532
00:27:31,714 --> 00:27:34,159
with those on the strip
and found on the runway.
533
00:27:37,987 --> 00:27:40,832
The French
judiciary now had its culprit.
534
00:27:40,841 --> 00:27:43,632
They proceeded to sue
continental airlines,
535
00:27:43,667 --> 00:27:45,552
demanding that it pay 70%
536
00:27:45,587 --> 00:27:47,679
of the victims'
compensation claims.
537
00:27:49,801 --> 00:27:51,799
With the investigation complete,
538
00:27:51,874 --> 00:27:54,879
the French bureau d'enquetes
published the findings.
539
00:27:56,034 --> 00:27:57,952
They concluded that
the metal strip
540
00:27:58,027 --> 00:28:00,912
had triggered a disastrous
sequence of events,
541
00:28:00,947 --> 00:28:04,319
resulting in the
failure of flight 4590.
542
00:28:11,507 --> 00:28:14,672
The entire concorde fleet
on both sides of the channel
543
00:28:14,681 --> 00:28:17,719
underwent the implementation
of new safety features.
544
00:28:18,947 --> 00:28:20,832
But, as is often the case
545
00:28:20,867 --> 00:28:23,272
with an accident
of this magnitude,
546
00:28:23,347 --> 00:28:26,592
there was disagreement with
the report's conclusions
547
00:28:26,627 --> 00:28:30,079
and a wide range of conjecture
by private citizens.
548
00:28:33,707 --> 00:28:37,472
John hutchinson, who piloted
concorde for 15 years,
549
00:28:37,507 --> 00:28:39,279
was one of the dissenters.
550
00:28:40,627 --> 00:28:42,472
One of the first
things that struck me
551
00:28:42,547 --> 00:28:44,519
when I read the
French accident report
552
00:28:44,594 --> 00:28:46,832
was the amount of taxi fuel
553
00:28:46,867 --> 00:28:49,639
that captain Marty
had opted to take.
554
00:28:49,714 --> 00:28:53,159
Now the standard air
France taxi fuel figure
555
00:28:53,234 --> 00:28:54,912
for flights out of
Charles de gaulle
556
00:28:54,947 --> 00:28:58,432
was 1,000 kilos, one metric ton.
557
00:28:58,507 --> 00:29:01,592
Captain Marty opted,
for whatever reason,
558
00:29:01,667 --> 00:29:05,152
to take 2,000 kilos,
two metric tons,
559
00:29:05,227 --> 00:29:08,352
twice the air France
standard figure.
560
00:29:08,387 --> 00:29:12,432
Now that fuel would have
been located in tank 11,
561
00:29:12,507 --> 00:29:16,112
right back there in the
tail cone of the airplane.
562
00:29:16,147 --> 00:29:17,639
Now the significance of this is
563
00:29:17,714 --> 00:29:22,072
because he only burnt off
800 kilos of that fuel
564
00:29:22,147 --> 00:29:24,032
when he was cleared for takeoff,
565
00:29:24,067 --> 00:29:27,952
that meant that there were
1.2 metric tons of fuel
566
00:29:27,987 --> 00:29:31,639
located in tank 11 in
the tail cone there
567
00:29:31,714 --> 00:29:33,792
that should not have been there.
568
00:29:33,827 --> 00:29:38,799
This was compounded by the
fact that there were 19 bags
569
00:29:39,254 --> 00:29:41,719
put on the airplane
at the last moment.
570
00:29:41,794 --> 00:29:43,119
They were never weighed.
571
00:29:44,467 --> 00:29:46,672
And we will never
know, of course,
572
00:29:46,707 --> 00:29:49,272
exactly what those bags
would have weighed.
573
00:29:49,347 --> 00:29:52,472
But bearing in mind these
were German passengers
574
00:29:52,547 --> 00:29:54,319
going on a trip of a lifetime,
575
00:29:55,287 --> 00:29:58,839
going on a cruise on the
cruise ship the deutschland,
576
00:29:58,914 --> 00:30:00,632
I think it's safe to assume
577
00:30:00,707 --> 00:30:02,992
that they were
pretty heavy bags,
578
00:30:03,027 --> 00:30:06,999
and I think maybe 500 kilos
would be a reasonable estimate
579
00:30:07,074 --> 00:30:08,719
of the weight of those bags.
580
00:30:11,347 --> 00:30:13,752
Hutchinson
believes the unburned taxi fuel
581
00:30:13,827 --> 00:30:15,392
and extra baggage
582
00:30:15,427 --> 00:30:19,072
would have added 1.7 metric
tons to the aircraft,
583
00:30:19,107 --> 00:30:21,632
putting it over the
maximum takeoff weight
584
00:30:21,667 --> 00:30:23,839
and altering the plane's
center of gravity.
585
00:30:26,147 --> 00:30:27,992
The significance of
the center of gravity
586
00:30:28,001 --> 00:30:30,072
being too far off
587
00:30:30,147 --> 00:30:32,752
essentially means that
the airplane becomes
588
00:30:32,787 --> 00:30:35,232
very, very, very unstable,
589
00:30:35,307 --> 00:30:38,512
and, if you get the center
of gravity too far off,
590
00:30:38,521 --> 00:30:42,032
it becomes completely
uncontrollable, in fact.
591
00:30:42,067 --> 00:30:43,479
And adding
to the weight issue
592
00:30:43,554 --> 00:30:45,152
was the main flight fuel
593
00:30:45,187 --> 00:30:47,559
that concorde was
carrying in its wings.
594
00:30:48,487 --> 00:30:52,432
Now, the refueling
procedures with concorde
595
00:30:52,507 --> 00:30:56,032
were that you could not
overfill those tanks,
596
00:30:56,067 --> 00:30:58,272
that would be cut
off automatically
597
00:30:58,307 --> 00:31:01,272
at around 82-83%
of tank capacity
598
00:31:01,347 --> 00:31:06,199
so that you had air
space left in the tanks.
599
00:31:06,274 --> 00:31:10,272
Now on that day captain
Marty authorized
600
00:31:10,307 --> 00:31:13,272
the overriding of
that protection
601
00:31:13,347 --> 00:31:14,839
and instructed the refuelers
602
00:31:14,914 --> 00:31:19,279
to fill the tanks in the
wing completely full.
603
00:31:21,987 --> 00:31:24,912
So captain Marty
started his takeoff,
604
00:31:24,947 --> 00:31:27,399
the airplane's accelerating
down the runway,
605
00:31:28,141 --> 00:31:32,832
it's gone past v1,
v1 was 150 knots.
606
00:31:32,867 --> 00:31:35,559
And at 176 knots,
607
00:31:36,627 --> 00:31:39,392
this front right-hand tire
608
00:31:39,427 --> 00:31:41,632
on the left-hand
undercarriage leg
609
00:31:41,667 --> 00:31:44,359
ran over a piece of titanium,
610
00:31:44,434 --> 00:31:45,439
and that piece of
titanium sliced off
611
00:31:47,827 --> 00:31:52,512
a 4 1/2-kilo lump of
rubber from this tire.
612
00:31:52,547 --> 00:31:56,112
Now that lump of rubber
parted company with the tire
613
00:31:56,147 --> 00:31:58,592
more or less with the
velocity of a missile
614
00:31:58,627 --> 00:32:00,752
and it went
absolutely slamming up
615
00:32:00,787 --> 00:32:03,839
into the underside of the
wing by tank number five
616
00:32:04,701 --> 00:32:07,519
and it set up a shock
wave in that fuel tank.
617
00:32:09,161 --> 00:32:11,312
With no air
space in the fuel tank
618
00:32:11,347 --> 00:32:13,072
to absorb the shock wave,
619
00:32:13,107 --> 00:32:15,399
the energy ruptured
the tank skin.
620
00:32:16,707 --> 00:32:18,472
And that's a
direct consequence
621
00:32:18,547 --> 00:32:20,512
of captain Marcy's decision
622
00:32:20,547 --> 00:32:23,879
to override the normal
refueling processes.
623
00:32:25,587 --> 00:32:27,152
Other
crash site evidence
624
00:32:27,187 --> 00:32:30,999
contributed to hutchinson's
human error theory.
625
00:32:31,074 --> 00:32:34,672
Flight 4590's final
movements on the runway
626
00:32:34,707 --> 00:32:37,119
were recorded in
thick sooty tracks.
627
00:32:38,707 --> 00:32:40,272
They revealed that
the plane veered
628
00:32:40,307 --> 00:32:42,632
dramatically to the left.
629
00:32:42,707 --> 00:32:46,432
The other features on the
runway were a blob of fuel
630
00:32:46,507 --> 00:32:51,519
almost immediately followed
by a very heavy trail of soot.
631
00:32:53,627 --> 00:32:57,632
And the trail, surprisingly,
632
00:32:57,667 --> 00:33:01,552
started veering off to the
left, away from the center line,
633
00:33:01,627 --> 00:33:04,999
to the point where the
left main landing gear
634
00:33:05,074 --> 00:33:09,319
ran onto the grass and
struck the runway edge light.
635
00:33:10,214 --> 00:33:12,352
It may be
that the plane lost thrust
636
00:33:12,361 --> 00:33:14,839
on both engines
under the left wing.
637
00:33:15,987 --> 00:33:18,199
But why hadn't the
captain corrected it?
638
00:33:20,067 --> 00:33:22,112
If an airplane
starts veering to the left,
639
00:33:22,147 --> 00:33:27,312
you put it in right rather
to keep it straight.
640
00:33:27,321 --> 00:33:29,232
The flight data
recorded showed
641
00:33:29,267 --> 00:33:33,439
that the pilot who was
handling the aircraft
642
00:33:34,387 --> 00:33:35,919
had put the right pedal on
643
00:33:37,067 --> 00:33:40,519
but it hadn't gone
the full right pedal,
644
00:33:40,594 --> 00:33:42,319
which is is kind of weird.
645
00:33:43,667 --> 00:33:45,159
With
his interest piqued,
646
00:33:45,234 --> 00:33:47,952
Tony cable and a
British airways engineer
647
00:33:47,987 --> 00:33:50,832
inspected the landing
gear wreckage.
648
00:33:50,841 --> 00:33:52,352
It wasn't very easy
649
00:33:52,387 --> 00:33:55,072
because it had been
removed from the site
650
00:33:55,107 --> 00:33:59,432
and just thrown in piles
really in a warehouse,
651
00:33:59,507 --> 00:34:04,752
and the ba guy fairly
rapidly noticed
652
00:34:04,787 --> 00:34:07,072
that there was
something not right
653
00:34:07,107 --> 00:34:09,279
with the left main landing gear,
654
00:34:09,314 --> 00:34:12,399
in that there appeared
to be a part missing.
655
00:34:14,227 --> 00:34:16,512
The four wheels
on the main landing gear
656
00:34:16,547 --> 00:34:20,079
were fixed to a bogie beam
that could pivot up and down.
657
00:34:21,347 --> 00:34:23,632
The two bearings that
allowed this movement
658
00:34:23,667 --> 00:34:26,032
were held in place by
a cylindrical spacer
659
00:34:26,107 --> 00:34:29,472
that ensured the two pairs
of wheels, left and right,
660
00:34:29,481 --> 00:34:31,279
were kept in proper alignment.
661
00:34:33,001 --> 00:34:35,439
It was this spacer
that was missing.
662
00:34:37,554 --> 00:34:39,159
One week before the crash,
663
00:34:39,234 --> 00:34:41,432
the landing gear
had been serviced.
664
00:34:41,507 --> 00:34:43,072
When it was reassembled,
665
00:34:43,147 --> 00:34:45,719
the maintenance crew failed
to put the spacer back.
666
00:34:47,827 --> 00:34:50,432
Procedures for
maintaining aircraft
667
00:34:50,507 --> 00:34:53,992
are all laid down
in great detail.
668
00:34:54,001 --> 00:34:58,959
But, inevitably, on occasions,
you do get human error.
669
00:34:59,687 --> 00:35:02,192
Could the missing
spacer have contributed
670
00:35:02,201 --> 00:35:06,032
to the pilot's failure to
keep the plane on the runway?
671
00:35:06,067 --> 00:35:08,479
The fact that he
was unable to control
672
00:35:09,127 --> 00:35:11,632
that veering off to the left
673
00:35:11,667 --> 00:35:13,959
is as much as anything
due to the fact
674
00:35:14,034 --> 00:35:16,272
that the spacer was missing,
675
00:35:16,307 --> 00:35:17,759
and with the spacer missing
676
00:35:18,667 --> 00:35:20,952
those wheels could wobble around
677
00:35:21,027 --> 00:35:22,999
like wheels on a
supermarket trolley.
678
00:35:25,107 --> 00:35:26,679
By
veering to the left,
679
00:35:26,754 --> 00:35:31,232
flight 4590 put itself on a
potential collision course
680
00:35:31,267 --> 00:35:34,679
with a boeing 747 at
the side of the runway.
681
00:35:35,827 --> 00:35:37,512
It was the same
plane that carried
682
00:35:37,587 --> 00:35:40,799
the French president
Jacques chirac and his wife.
683
00:35:41,827 --> 00:35:43,959
To avoid the 747,
684
00:35:44,034 --> 00:35:47,232
captain Marty was forced to
pull back on the control column
685
00:35:47,307 --> 00:35:49,079
and get concorde airborne.
686
00:35:50,547 --> 00:35:54,919
But the fate of flight
4590 was already sealed.
687
00:35:56,507 --> 00:35:58,319
The airspeed,
the airspeed.
688
00:36:00,274 --> 00:36:01,312
Le bourget, le bourget.
689
00:36:01,347 --> 00:36:03,319
We are trying for le bourget.
690
00:36:03,394 --> 00:36:05,039
Too late, no time, no.
691
00:36:10,841 --> 00:36:15,432
As concorde flight
4590 attempted to take off,
692
00:36:15,507 --> 00:36:17,752
it veered to the
edge of the runway,
693
00:36:17,827 --> 00:36:20,152
putting it on a potential
collision course
694
00:36:20,227 --> 00:36:22,119
with a boeing 747.
695
00:36:23,187 --> 00:36:25,312
Captain Marty was
forced to lift off
696
00:36:25,347 --> 00:36:28,152
at a speed well below 200 knots,
697
00:36:28,227 --> 00:36:30,752
concorde's minimum
takeoff speed.
698
00:36:33,394 --> 00:36:35,072
The surprising
thing that was shown
699
00:36:35,147 --> 00:36:40,312
by the flight data
recorded data was that
700
00:36:40,387 --> 00:36:44,152
the pilot had rotated
early for takeoff,
701
00:36:44,227 --> 00:36:45,712
in other words,
702
00:36:45,747 --> 00:36:47,839
at a lower speed than
they would normally do,
703
00:36:48,947 --> 00:36:51,712
and quite critical
on the concorde
704
00:36:51,787 --> 00:36:53,959
because of the delta wing.
705
00:36:54,034 --> 00:36:57,399
The minimum drag speed
is very, very high.
706
00:36:59,667 --> 00:37:01,472
It is the one thing
you would never do,
707
00:37:01,481 --> 00:37:03,152
is to rotate early,
708
00:37:03,187 --> 00:37:05,952
because you're creating
an enormous amount of drag
709
00:37:05,987 --> 00:37:09,479
as you lift the nose of the
airplane and the wing with it,
710
00:37:09,554 --> 00:37:13,272
and that drag is greater than
the thrust of the engine,
711
00:37:13,347 --> 00:37:16,472
and so the nose will drop and
it'll stall out, whatever.
712
00:37:16,547 --> 00:37:18,832
I can imagine
that the captain
713
00:37:18,867 --> 00:37:21,232
simply hold back on
the control column
714
00:37:21,267 --> 00:37:22,992
and so he didn't
go into the grass
715
00:37:23,001 --> 00:37:24,359
to the side of the runway.
716
00:37:25,127 --> 00:37:27,232
Once
concorde was airborne,
717
00:37:27,267 --> 00:37:29,712
the investigation
relied on information
718
00:37:29,787 --> 00:37:32,832
from the flight data and
cockpit voice recorders,
719
00:37:32,867 --> 00:37:34,239
the black boxes.
720
00:37:35,467 --> 00:37:36,952
What they revealed
721
00:37:37,027 --> 00:37:40,632
made an already desperate
situation even worse.
722
00:37:40,707 --> 00:37:42,032
Watch out.
723
00:37:42,107 --> 00:37:43,632
As the
aircraft got airborne,
724
00:37:43,707 --> 00:37:45,952
the fire warning for the
number two engine went off.
725
00:37:45,987 --> 00:37:48,359
So that light here
would have lit up
726
00:37:48,434 --> 00:37:50,799
and the fire warning
bell would have operated.
727
00:37:51,874 --> 00:37:53,919
What should have happened is
728
00:37:53,954 --> 00:37:56,032
that the flight
engineer should then
729
00:37:56,067 --> 00:37:58,592
have canceled the oral warning
730
00:37:58,627 --> 00:38:00,592
so that it doesn't
distract the pilot.
731
00:38:00,627 --> 00:38:03,152
He'd do that with
this switch here.
732
00:38:03,187 --> 00:38:07,112
And he would have then
selected contingency thrust
733
00:38:07,187 --> 00:38:09,512
on the reheats on
these switches here,
734
00:38:09,521 --> 00:38:13,912
giving another 8% or
so of reheated thrust.
735
00:38:13,987 --> 00:38:17,272
And then no further action
should have been taken
736
00:38:17,347 --> 00:38:20,752
until the aircraft was
safely climbing away.
737
00:38:20,787 --> 00:38:24,992
And then the crew would have
gone through the fire drill
738
00:38:25,027 --> 00:38:27,599
and then carry out all the
rest of the check list.
739
00:38:28,914 --> 00:38:31,112
What actually
happened on that day,
740
00:38:31,187 --> 00:38:33,472
uncommanded by the captain,
741
00:38:33,507 --> 00:38:36,752
the flight engineer,
at around 28 feet,
742
00:38:36,787 --> 00:38:39,799
so literally just as the
aircraft had got airborne,
743
00:38:39,874 --> 00:38:42,199
he went straight
into a fire drill.
744
00:38:42,274 --> 00:38:45,599
He pulled that fire handle
which shuts that engine down.
745
00:38:47,027 --> 00:38:51,712
And the unfortunate thing
was that that engine
746
00:38:51,747 --> 00:38:53,399
was actually
producing some power.
747
00:38:55,027 --> 00:38:57,152
Shutting engine two.
748
00:38:57,187 --> 00:38:58,632
Shut down engine two.
749
00:38:58,707 --> 00:38:59,952
And now, obviously,
750
00:38:59,987 --> 00:39:02,352
it was generating no
power at all.
751
00:39:04,867 --> 00:39:07,272
Are you shutting
down engine two there?
752
00:39:07,347 --> 00:39:08,912
I've shut it down.
753
00:39:08,987 --> 00:39:12,352
Engine number
two had never been on fire.
754
00:39:12,387 --> 00:39:13,752
It wasn't
a fire warning
755
00:39:13,827 --> 00:39:16,352
in the conventional
sense of the word.
756
00:39:16,387 --> 00:39:17,872
It was an overheat warning
757
00:39:17,907 --> 00:39:20,112
caused by this
blowtorch of flame
758
00:39:20,187 --> 00:39:22,432
going past the
number two engine,
759
00:39:22,467 --> 00:39:24,912
which is what triggered
that fire warning.
760
00:39:24,947 --> 00:39:27,432
So, basically, the
airplane at this stage
761
00:39:27,507 --> 00:39:31,239
was now flying with sort of
2 1/2 engines as it were.
762
00:39:41,667 --> 00:39:44,519
If they'd stuck to
operating the airplane
763
00:39:44,594 --> 00:39:46,199
in a standard way,
764
00:39:47,714 --> 00:39:51,599
then I would argue that
crash wouldn't have happened.
765
00:39:54,521 --> 00:39:56,472
Despite the
plausibility of theories
766
00:39:56,547 --> 00:39:59,632
promoted by enthusiastic and
knowledgeable individuals,
767
00:39:59,667 --> 00:40:02,432
the conclusions of the
professional investigation team
768
00:40:02,507 --> 00:40:04,112
are not in dispute.
769
00:40:04,121 --> 00:40:07,552
They stand by the accident
report's findings.
770
00:40:07,587 --> 00:40:09,712
My belief is
this crew operated
771
00:40:09,787 --> 00:40:11,872
to the best of their capability.
772
00:40:11,907 --> 00:40:15,152
They didn't get everything
right in terms of procedure,
773
00:40:15,187 --> 00:40:19,152
but actually the things where
they deviated from procedure
774
00:40:19,187 --> 00:40:20,792
I don't believe actually caused
775
00:40:20,867 --> 00:40:22,959
any difference with
the accident at all.
776
00:40:25,187 --> 00:40:28,432
Any accident, particularly
a tragic one like this,
777
00:40:28,467 --> 00:40:30,832
is where a number of
things come together.
778
00:40:30,867 --> 00:40:33,752
And on this particular
day we had coming together
779
00:40:33,827 --> 00:40:36,752
a particular piece of
metal lying on a runway,
780
00:40:36,787 --> 00:40:39,072
an aircraft happening
to run over that
781
00:40:39,147 --> 00:40:42,472
at a speed where it's
going too fast to stop,
782
00:40:42,547 --> 00:40:44,592
and you have a wing
structure there
783
00:40:44,667 --> 00:40:46,512
which has a vulnerability.
784
00:40:46,547 --> 00:40:49,472
The things about the
slight overweight,
785
00:40:49,481 --> 00:40:52,192
other things like
that, like the spacer,
786
00:40:52,227 --> 00:40:53,712
very small effects.
787
00:40:53,747 --> 00:40:57,479
Those are not really
factors in this at all.
788
00:40:57,554 --> 00:40:59,632
And at the end of
the day we think
789
00:40:59,667 --> 00:41:04,312
the bureau d'enquetes
report was just about right.
790
00:41:07,894 --> 00:41:11,072
Concorde
eventually resumed service,
791
00:41:11,147 --> 00:41:14,592
but the supersonic airliner
fell victim to 9/11
792
00:41:14,627 --> 00:41:16,799
and the downturn in
international travel.
793
00:41:18,914 --> 00:41:21,319
Air France was the first
to ground its fleet.
794
00:41:22,287 --> 00:41:25,592
And unable to bear the huge
maintenance costs alone,
795
00:41:25,667 --> 00:41:28,119
British airways was
forced to follow suit.
796
00:41:30,034 --> 00:41:32,992
The decision to
pursue concorde was state-led
797
00:41:33,027 --> 00:41:35,639
by the British government,
the French government,
798
00:41:35,714 --> 00:41:37,832
for all sorts of
reasons about prestige,
799
00:41:37,907 --> 00:41:39,159
about getting the technology
800
00:41:39,234 --> 00:41:41,152
before the Americans,
the Soviet union,
801
00:41:41,187 --> 00:41:43,152
and commercial arguments
802
00:41:43,161 --> 00:41:46,192
probably didn't enter
as much then
803
00:41:46,227 --> 00:41:48,952
into the equation as they
would do certainly now.
804
00:41:49,027 --> 00:41:51,392
Therefore we have at
the end of the day
805
00:41:51,427 --> 00:41:53,952
a beautiful plane
which looks amazing
806
00:41:53,987 --> 00:41:57,152
crosses the Atlantic at
this extraordinary speed,
807
00:41:57,187 --> 00:42:00,192
but it only takes 100
people on board, it's tiny.
808
00:42:00,227 --> 00:42:03,639
The logic of it now
looks almost laughable.
809
00:42:03,714 --> 00:42:05,112
Good morning to
you, nice to see you.
810
00:42:05,187 --> 00:42:06,999
Mind your head as
you board, hello.
811
00:42:07,074 --> 00:42:09,952
On
October 24th, 2003,
812
00:42:09,987 --> 00:42:13,392
concorde flew for the last time.
813
00:42:13,427 --> 00:42:14,592
I loved it.
814
00:42:14,627 --> 00:42:16,072
I never, ever thought
815
00:42:16,147 --> 00:42:18,672
when I used to drive
from here to Heathrow
816
00:42:18,681 --> 00:42:21,832
I never even considered
that it was work.
817
00:42:25,267 --> 00:42:28,599
Plane engine whooshing
818
00:42:35,507 --> 00:42:36,632
But for some,
819
00:42:36,707 --> 00:42:38,752
the name concorde
will always evoke
820
00:42:38,787 --> 00:42:40,679
different memories and emotions.
821
00:42:43,641 --> 00:42:45,392
I was at the wrong
place at the wrong time,
822
00:42:45,467 --> 00:42:47,952
or could be considered the
right place at the right time,
823
00:42:47,987 --> 00:42:50,912
so I was extraordinarily
fortunate to be
824
00:42:50,987 --> 00:42:53,152
in one of the handful of rooms
825
00:42:53,187 --> 00:42:56,432
that the fire didn't
reach quite as soon.
826
00:42:56,467 --> 00:42:59,152
It has made me think more
differently about life
827
00:42:59,187 --> 00:43:01,312
because you realize
just how fragile it is,
828
00:43:01,321 --> 00:43:03,552
and you realize,
more importantly,
829
00:43:03,627 --> 00:43:05,719
the utter
unpredictability of it.
830
00:43:09,987 --> 00:43:12,279
For me, after 20
years, it's different.
831
00:43:13,307 --> 00:43:14,592
The time has passed, you know?
832
00:43:14,627 --> 00:43:17,112
So I can speak
about the accident,
833
00:43:17,187 --> 00:43:18,912
even though I feel the emotion,
834
00:43:18,987 --> 00:43:22,999
because I feel a bit like
if I was in the plane.
835
00:43:23,074 --> 00:43:25,632
Obviously I'm not a survivor,
I was not in the crash,
836
00:43:25,667 --> 00:43:29,319
but in a way I survived
something, too.
