Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:17,391 --> 00:00:19,853
- I remember being amazed
how quickly
2
00:00:19,936 --> 00:00:21,437
the accident took place.
3
00:00:21,562 --> 00:00:23,440
They were flying and the next
thing you know,
4
00:00:23,565 --> 00:00:24,440
the airplane's lost.
5
00:00:28,236 --> 00:00:29,696
Midwest Express
Flight 1-0-5
6
00:00:29,821 --> 00:00:32,865
crashes seconds after taking
off from Milwaukee, Wisconsin.
7
00:00:32,948 --> 00:00:36,036
All 31 people on board
are killed.
8
00:00:36,118 --> 00:00:38,204
And what do you say
to the public
9
00:00:38,329 --> 00:00:40,247
about the crashes that we've
been having?
10
00:00:40,914 --> 00:00:43,710
1985 becomes one
of the deadliest years
11
00:00:43,835 --> 00:00:45,128
in civil aviation.
12
00:00:45,253 --> 00:00:48,381
It's up to investigators to put
the public at ease.
13
00:00:48,506 --> 00:00:51,259
- This is how the plane hit
the ground.
14
00:00:51,759 --> 00:00:53,261
When they examine
the engines,
15
00:00:53,386 --> 00:00:56,014
they find a component
prone to failure.
16
00:00:56,805 --> 00:00:58,557
Well, when we had
heard that this part
17
00:00:58,640 --> 00:01:02,896
had failed 45 times before,
that's a big deal.
18
00:01:03,563 --> 00:01:06,566
But the flight data
turns the investigation
on its head.
19
00:01:06,649 --> 00:01:09,736
- So the ruptured right engine
didn't bring down this plane.
20
00:01:09,819 --> 00:01:11,905
- It did not.
21
00:01:11,987 --> 00:01:14,490
- Mayday! Mayday!
22
00:01:34,593 --> 00:01:36,930
There are 27
passengers boarding
23
00:01:37,013 --> 00:01:39,724
Midwest Express Airlines
Flight 1-0-5,
24
00:01:39,808 --> 00:01:43,644
a commuter flight from
Milwaukee, to Atlanta.
25
00:01:43,769 --> 00:01:44,978
Many are employees
26
00:01:45,105 --> 00:01:47,397
of the manufacturer
Kimberley Clark.
27
00:01:48,816 --> 00:01:51,528
- Midwest Express Airlines used
the slogan:
28
00:01:51,653 --> 00:01:53,780
"Best Care in the Air," and
they really meant it
29
00:01:53,862 --> 00:01:58,034
because they had as close
to an all-business aircraft
30
00:01:58,159 --> 00:01:59,284
as you could have.
31
00:02:00,912 --> 00:02:02,621
- Treats for when we're
airborne.
32
00:02:04,498 --> 00:02:08,627
- And they also baked fresh
cookies on board
33
00:02:08,752 --> 00:02:12,173
and made the place smell amazing
when you walked on.
34
00:02:14,842 --> 00:02:19,139
- Midex 1-0-5 requesting
IFR clearance to Atlanta.
35
00:02:20,348 --> 00:02:22,808
Both pilots
on this flight are captains
36
00:02:22,891 --> 00:02:24,185
with the airline.
37
00:02:24,310 --> 00:02:26,770
They've already flown two
flights together today.
38
00:02:31,234 --> 00:02:32,860
- Midex 1-0-5, cleared
to Atlanta,
39
00:02:32,985 --> 00:02:35,280
climb and maintain 5000.
40
00:02:36,447 --> 00:02:39,449
- Climb and maintain 5000.
Midex 1-0-5.
41
00:02:40,075 --> 00:02:41,243
For this leg
of the flight,
42
00:02:41,368 --> 00:02:43,580
Danny Martin will be
the acting captain
43
00:02:43,705 --> 00:02:45,747
and Bill Weiss,
the first officer.
44
00:02:46,248 --> 00:02:49,460
- You had two captains
and they... they literally
45
00:02:49,544 --> 00:02:51,587
could switch seats
because of that.
46
00:02:51,712 --> 00:02:54,174
And they did do that over
the course of two days,
47
00:02:54,299 --> 00:02:56,884
flipping out who was the pilot
flying
48
00:02:57,009 --> 00:02:58,343
and who was the pilot
not flying.
49
00:02:58,427 --> 00:03:02,723
- Uh, our alternate will be DCA
if we can't make Atlanta.
50
00:03:03,515 --> 00:03:05,810
There are
thunderstorms in Atlanta,
51
00:03:05,894 --> 00:03:08,729
so the crew has taken
on additional fuel
52
00:03:08,854 --> 00:03:11,399
in case they have to divert
to another airport.
53
00:03:13,610 --> 00:03:17,280
- Takeoff weight is 7-7-1-2-2
pounds. Set stab trim 2.2.
54
00:03:21,617 --> 00:03:24,162
Just past 3
in the afternoon,
55
00:03:24,245 --> 00:03:25,830
the pilots start the engines.
56
00:03:29,250 --> 00:03:31,502
- Starting number one.
57
00:03:32,920 --> 00:03:35,465
The DC-9 used
for today's flight
58
00:03:35,590 --> 00:03:38,425
is powered by two
Pratt and Whitney engines
59
00:03:38,550 --> 00:03:41,554
mounted on the fuselage
at the rear of the plane.
60
00:03:43,848 --> 00:03:46,975
- Because the engines
were in the back,
61
00:03:47,100 --> 00:03:50,938
they were close together, which
made for a little bit easier
62
00:03:51,063 --> 00:03:52,606
flying in emergency situations.
63
00:03:52,731 --> 00:03:55,693
Second of all, for
the passengers, it's quieter.
64
00:03:55,776 --> 00:03:59,447
- Thank you.
65
00:03:59,572 --> 00:04:01,574
Can I put that up here for you?
66
00:04:02,824 --> 00:04:04,117
Thank you.
67
00:04:04,242 --> 00:04:08,914
The plane is loaded
and ready to depart on schedule.
68
00:04:12,335 --> 00:04:15,212
- Airspeed bug, 1-33 set.
69
00:04:15,295 --> 00:04:17,632
And, ah, 1.9 on the EPR
70
00:04:17,757 --> 00:04:18,757
- Okay.
71
00:04:26,139 --> 00:04:27,432
Ladies and gentlemen,
72
00:04:27,557 --> 00:04:30,019
we are number one for departure
so we should be airborne
73
00:04:30,144 --> 00:04:31,437
within one minute.
74
00:04:31,562 --> 00:04:33,523
Flight attendants please
be seated.
75
00:04:38,278 --> 00:04:41,656
- Midex 1-0-5 cleared
for takeoff.
76
00:04:41,781 --> 00:04:44,951
- Midex 1-0-5.
77
00:04:48,329 --> 00:04:51,665
- Here we go. Spooling up.
78
00:04:55,670 --> 00:04:58,213
- This was a very
normal morning,
79
00:04:58,338 --> 00:05:00,132
for a very normal flight.
80
00:05:00,257 --> 00:05:03,427
It was a gorgeous blue sky,
September day.
81
00:05:03,511 --> 00:05:06,639
There was a little bit
of gusty winds,
82
00:05:06,764 --> 00:05:09,350
but it was nothing
for Milwaukee.
83
00:05:11,185 --> 00:05:15,273
- Power normal. One hundred.
84
00:05:16,357 --> 00:05:20,235
The pilots need
to reach a speed of 127 knots
for take-off.
85
00:05:20,360 --> 00:05:24,781
- V-1. Rotate.
86
00:05:29,661 --> 00:05:31,331
At 3:21
in the afternoon,
87
00:05:31,456 --> 00:05:34,875
Flight 1-0-5 begins its journey.
88
00:05:37,545 --> 00:05:39,880
The flight plan calls
for the plane to climb
89
00:05:40,005 --> 00:05:44,343
to an altitude of 33 000 feet
for the 2-hour trip to Atlanta.
90
00:05:50,432 --> 00:05:52,017
- Gear Up.
91
00:05:53,394 --> 00:05:56,646
Just 450 feet
above the ground...
92
00:06:00,401 --> 00:06:03,112
What the hell was that?
93
00:06:03,362 --> 00:06:06,865
...the pilots lose
power in one of the engines.
94
00:06:08,242 --> 00:06:10,745
- It's a critical situation
because if you don't do
95
00:06:10,870 --> 00:06:13,538
something about it immediately,
you won't have time
96
00:06:13,663 --> 00:06:17,043
to do anything about it.
Altitude is your friend.
97
00:06:22,423 --> 00:06:23,800
Midex 1-0-5,
98
00:06:23,925 --> 00:06:26,009
turn left heading 1-7-5.
99
00:06:28,678 --> 00:06:32,725
- What have we got here, Bill?
Here!
100
00:06:33,810 --> 00:06:38,814
- Midex 1-0-5 roger,
ah we got an emergency here.
101
00:06:40,608 --> 00:06:42,567
- Midex 1-0-5, roger.
102
00:06:44,278 --> 00:06:46,406
The plane begins
rolling to the right
103
00:06:46,488 --> 00:06:47,865
and dropping.
104
00:06:50,867 --> 00:06:52,786
- Oh crap!
105
00:06:53,829 --> 00:06:56,040
The DC-9
is stalling.
106
00:06:58,543 --> 00:07:00,961
- Get your heads down.
107
00:07:06,634 --> 00:07:09,387
Heads down! Heads down!
108
00:07:11,721 --> 00:07:14,434
Less than a minute
after takeoff,
109
00:07:14,559 --> 00:07:17,060
Flight 1-0-5 is diving towards
the ground
110
00:07:17,144 --> 00:07:20,105
at more than 170 miles an hour.
111
00:07:31,701 --> 00:07:32,994
The plane hits
the ground
112
00:07:33,119 --> 00:07:36,038
less than 17-hundred feet
from the runway.
113
00:07:38,124 --> 00:07:42,043
- A DC-9 has crashed southwest
of runway 1-9-right.
114
00:07:50,845 --> 00:07:54,807
All 31 people
on board have been killed.
115
00:07:59,644 --> 00:08:02,355
The crash of Midwest Express
Flight 1-0-5
116
00:08:02,482 --> 00:08:05,735
is the third major accident
in the United States this year
117
00:08:05,860 --> 00:08:08,821
and the eighth accident
worldwide.
118
00:08:08,946 --> 00:08:12,867
With more than 12-hundred people
killed, this is becoming
119
00:08:12,992 --> 00:08:15,076
one of the deadliest years
in the history
120
00:08:15,202 --> 00:08:16,995
of civil aviation.
121
00:08:17,079 --> 00:08:18,831
Passengers are unnerved.
122
00:08:19,540 --> 00:08:21,666
Everyone says:
"My God, another one."
123
00:08:21,750 --> 00:08:24,002
What do you say to the public
about the crashes
124
00:08:24,127 --> 00:08:25,338
that we've been having?
125
00:08:25,420 --> 00:08:27,255
- Well, insofar as the National
Transportation Safety Board
126
00:08:27,380 --> 00:08:29,675
is concerned, we are sparing
no effort to determine the cause
127
00:08:29,759 --> 00:08:31,843
of each one of them and we will
make the necessary
128
00:08:31,927 --> 00:08:34,388
recommendations to keep
any repeat of any one of them
129
00:08:34,514 --> 00:08:35,347
from happening.
130
00:08:39,268 --> 00:08:41,354
- Can you show me where
it started to bank?
131
00:08:42,605 --> 00:08:45,899
Investigators from
the NTSB begin by interviewing
132
00:08:46,024 --> 00:08:50,111
witnesses of Midwest Express
Flight 1-0-5's fatal dive.
133
00:08:51,072 --> 00:08:53,365
They either came
forward or we tracked them down.
134
00:08:53,490 --> 00:08:55,533
We ended up making out
a questionnaire
135
00:08:55,618 --> 00:08:59,246
with 40 or 50 questions on it
to kind of cover all the bases.
136
00:09:02,124 --> 00:09:03,793
- OK, got it.
137
00:09:07,922 --> 00:09:10,006
While the witness
accounts differ in detail,
138
00:09:10,091 --> 00:09:13,260
they all describe more or less
the same thing.
139
00:09:14,302 --> 00:09:16,889
- I saw a couple of puffs
of black smoke come out
140
00:09:16,972 --> 00:09:19,683
and I, I just figured that
they had gunned the engines
141
00:09:19,767 --> 00:09:22,352
a little bit. An instant later
the left wing rolls up
142
00:09:22,436 --> 00:09:27,149
and it tipped over and it went
nose first into the trees here.
143
00:09:30,360 --> 00:09:32,779
Most of
the witnesses agree that takeoff
144
00:09:32,904 --> 00:09:36,450
appeared normal until
the airplane was about 300 feet
145
00:09:36,576 --> 00:09:37,994
from the ground.
146
00:09:38,119 --> 00:09:42,038
Almost all report smoke and fire
coming from the right engine
147
00:09:42,123 --> 00:09:44,917
several remember
loud bangs.
148
00:09:45,042 --> 00:09:47,628
Most said that the plane
then rolled abruptly
149
00:09:47,753 --> 00:09:52,383
into a steep right bank,
went into a nose-low spin
and crashed.
150
00:09:56,345 --> 00:09:59,724
- The value of having
so many witness statements
151
00:09:59,807 --> 00:10:02,600
to look at was that they gave us
a picture of what happened
152
00:10:02,684 --> 00:10:06,563
right at the end, a loss
of control, a fire,
153
00:10:06,647 --> 00:10:08,774
and, of course,
the impact itself.
154
00:10:09,232 --> 00:10:11,152
Investigators must
now determine
155
00:10:11,277 --> 00:10:15,615
what could have caused such
a catastrophic loss of control
156
00:10:15,697 --> 00:10:17,950
so soon after takeoff.
157
00:10:21,287 --> 00:10:23,163
- I'm guessing this was made
by the right wing.
158
00:10:23,288 --> 00:10:25,957
- Yup, agreed.
159
00:10:30,171 --> 00:10:31,880
- Let's see what we can
figure out.
160
00:10:32,380 --> 00:10:34,133
After securing
the crash site
161
00:10:34,216 --> 00:10:38,471
of Midwest Express Flight 1-0-5,
investigators begin mapping
162
00:10:38,553 --> 00:10:39,971
the wreckage field.
163
00:10:40,722 --> 00:10:42,975
I think the whole
length of the impact site
164
00:10:43,100 --> 00:10:46,479
was about 295 feet, not much
more than two times
165
00:10:46,604 --> 00:10:48,063
the length of the airplane.
166
00:10:48,188 --> 00:10:52,485
So the airplane hit pretty
steeply and didn't go very far.
167
00:10:53,778 --> 00:10:59,325
- Right-wing tip here, and
horizontal stabilizer here.
168
00:11:01,409 --> 00:11:03,620
This is how the plane hit
the ground.
169
00:11:03,703 --> 00:11:08,542
A 90-degree right roll,
and a right yaw.
170
00:11:12,421 --> 00:11:14,631
Can you grab a picture?
- You got it.
171
00:11:16,216 --> 00:11:19,511
The wreckage path
confirms eyewitness reports.
172
00:11:20,721 --> 00:11:23,182
It very definitely
indicates right up front
173
00:11:23,307 --> 00:11:24,557
that you've got a loss
of control.
174
00:11:24,682 --> 00:11:27,311
It doesn't suggest why you had
the loss of control.
175
00:11:27,394 --> 00:11:29,437
It kind of opens the door
to a lot of different
176
00:11:29,562 --> 00:11:30,815
investigative avenues.
177
00:11:33,734 --> 00:11:36,570
- Yeah, it's fire damage for
sure, but it looks like
178
00:11:36,696 --> 00:11:38,072
all the pieces are here.
179
00:11:39,740 --> 00:11:42,659
Investigators study
the plane's control surfaces,
180
00:11:42,743 --> 00:11:44,745
starting with the ailerons.
181
00:11:46,246 --> 00:11:49,041
The ailerons on each wing direct
the plane's roll.
182
00:11:49,166 --> 00:11:54,337
If an aileron malfunctions and
gets stuck in one position,
183
00:11:54,422 --> 00:11:57,716
it could cause a devastating
lack of control.
184
00:12:00,760 --> 00:12:03,556
- Control tabs are in place.
They seem to be intact.
185
00:12:05,349 --> 00:12:08,601
We didn't find
a problem with other components
186
00:12:08,726 --> 00:12:10,145
that are part of that system.
187
00:12:11,772 --> 00:12:13,774
With the ailerons
ruled out,
188
00:12:13,899 --> 00:12:15,359
investigators turn
their attention
189
00:12:15,442 --> 00:12:17,445
to the rudder system.
190
00:12:18,946 --> 00:12:22,615
- The dampers are still working.
The hinges are intact.
191
00:12:24,701 --> 00:12:27,413
The fractures look like
overload, not stress.
192
00:12:29,664 --> 00:12:31,750
I don't think the rudder
is our culprit.
193
00:12:33,586 --> 00:12:35,754
- We didn't find
anything wrong with any
194
00:12:35,879 --> 00:12:39,549
of the control systems based
on that preliminary look-see.
195
00:12:40,884 --> 00:12:44,263
Could the engines
provide insight into the crash
196
00:12:44,388 --> 00:12:46,890
of Midwest Express Flight 1-0-5?
197
00:12:48,142 --> 00:12:50,436
If the engines
were, well, obviously banged up,
198
00:12:50,519 --> 00:12:52,855
they were fire-damaged,
and they were along
199
00:12:52,980 --> 00:12:55,399
the wreckage path,
which is always good,
200
00:12:55,482 --> 00:12:59,153
it means they didn't
fall off somewhere earlier.
201
00:13:02,697 --> 00:13:04,700
- There's a spacer missing here.
202
00:13:09,038 --> 00:13:13,000
And most of the blades
from this stage are gone.
203
00:13:14,000 --> 00:13:17,296
The team finds
damage inside the right engine
204
00:13:17,379 --> 00:13:19,881
that could not have been caused
on impact.
205
00:13:20,841 --> 00:13:23,219
The missing engine pieces
include a spacer
206
00:13:23,344 --> 00:13:25,553
and the compressor blades
207
00:13:25,678 --> 00:13:28,515
from the 9th and 10th
compressor stages.
208
00:13:29,975 --> 00:13:31,811
They're found more than
half a mile
209
00:13:31,894 --> 00:13:33,812
from the main wreckage site.
210
00:13:33,895 --> 00:13:36,524
- Finding any part
of the airplane
211
00:13:36,649 --> 00:13:40,152
short of where the airplane
crashed was a suggestion
212
00:13:40,277 --> 00:13:43,655
of a malfunction or failure that
had occurred in-flight
213
00:13:43,780 --> 00:13:46,826
and required further
investigation.
214
00:13:47,993 --> 00:13:49,537
The engine and
the pieces are moved
215
00:13:49,662 --> 00:13:53,331
to a nearby warehouse where
they can be more closely
examined.
216
00:13:53,999 --> 00:13:55,835
In the end,
though, we ended up finding
217
00:13:55,918 --> 00:13:58,671
about 90% by weight
of the spacer,
218
00:13:58,796 --> 00:14:01,923
so, that was a big boon
to the investigation.
219
00:14:02,883 --> 00:14:05,260
Investigators study
the recovered spacer
220
00:14:05,385 --> 00:14:09,849
to determine why it failed
on Midwest Express Flight 1-0-5.
221
00:14:11,725 --> 00:14:13,936
- All along the pedestal, here.
222
00:14:16,312 --> 00:14:17,730
It's definitely not overstress.
223
00:14:19,357 --> 00:14:22,360
They discover
a tell-tale crack on the spacer
224
00:14:22,443 --> 00:14:25,029
that appears to have spread
over time,
225
00:14:25,154 --> 00:14:26,990
what's called
"progressive cracking."
226
00:14:27,073 --> 00:14:31,578
- There may be stress marks.
There may be, uh, cracks.
227
00:14:31,703 --> 00:14:34,623
There, there may be things that,
that suggest a direction
228
00:14:34,748 --> 00:14:36,875
of failure and, and a timeframe
229
00:14:37,000 --> 00:14:38,751
where the fracture would
have occurred.
230
00:14:38,878 --> 00:14:41,254
It doesn't occur all
at one time.
231
00:14:42,047 --> 00:14:44,549
- Can we determine how long that
crack has been spreading for?
232
00:14:44,674 --> 00:14:46,217
- I'll see what I can do.
233
00:14:48,220 --> 00:14:51,557
- We became interested
not just in detailing
234
00:14:51,682 --> 00:14:54,684
that but trying to find whether
this was a fracture
235
00:14:54,768 --> 00:14:57,104
that could have been detected
previously.
236
00:14:58,022 --> 00:15:00,524
A closer look
at the crack on the steel spacer
237
00:15:00,607 --> 00:15:03,110
reveals it is filled
with nickel.
238
00:15:04,153 --> 00:15:06,572
A light-weight nickel coating
is applied to certain
239
00:15:06,697 --> 00:15:09,325
vital engine pieces like
the compressor spacers
240
00:15:09,450 --> 00:15:11,744
and blades to prevent corrosion.
241
00:15:14,538 --> 00:15:17,917
- The compressor was brought
in to be refurbished in 1981.
242
00:15:18,000 --> 00:15:23,254
Coating stripped, spacer
examined and, oh, here we go,
243
00:15:24,590 --> 00:15:25,923
re-plated.
244
00:15:27,384 --> 00:15:28,469
- That was 4 years ago.
245
00:15:29,052 --> 00:15:31,804
The maintenance
records tell investigators
246
00:15:31,931 --> 00:15:34,099
that work had been done
on the spacer
247
00:15:34,182 --> 00:15:37,269
that failed on Midwest Express
Flight 1-0-5.
248
00:15:37,352 --> 00:15:41,356
Nickel cadmium
plating is the last step
249
00:15:41,481 --> 00:15:45,193
of the refurbishment process
that would have been done
250
00:15:45,318 --> 00:15:47,904
by the maintenance facility
that was involved
251
00:15:47,988 --> 00:15:50,282
with essentially the overhaul
of that part.
252
00:15:50,783 --> 00:15:53,118
Four years before
the accident,
253
00:15:53,201 --> 00:15:55,287
the spacer was removed from
the engine,
254
00:15:55,412 --> 00:15:58,164
stripped of its coating,
and examined for cracks.
255
00:15:58,289 --> 00:16:02,461
The inspector reported
no cracks and sent the part
256
00:16:02,543 --> 00:16:03,961
to be re-plated with nickel.
257
00:16:04,754 --> 00:16:07,131
Since nickel was found inside
the crack,
258
00:16:07,256 --> 00:16:10,177
it must have been present when
the nickel was applied.
259
00:16:14,682 --> 00:16:19,311
The DC-9 flew about 25-hundred
flights over the next 4 years
260
00:16:19,436 --> 00:16:22,648
with the damaged spacer until
it finally ruptured
261
00:16:22,773 --> 00:16:24,482
on Flight 1-0-5.
262
00:16:27,903 --> 00:16:30,072
- This should have
been caught during an overhaul,
263
00:16:30,197 --> 00:16:31,532
but it wasn't.
264
00:16:31,657 --> 00:16:33,783
And so the crack kept growing
and growing
265
00:16:33,866 --> 00:16:36,537
until it finally hit
its failure point.
266
00:16:37,620 --> 00:16:40,832
Investigators wonder
what caused the crack to form
267
00:16:40,957 --> 00:16:42,750
on the spacer
in the first place.
268
00:16:43,793 --> 00:16:46,839
- These spacers have been used
inside the JT8D
269
00:16:46,922 --> 00:16:47,965
for more than 20 years.
270
00:16:48,048 --> 00:16:50,341
This can't be the first
one to break.
271
00:16:53,386 --> 00:16:55,514
There are identical
spacers in more than
272
00:16:55,639 --> 00:17:00,561
1400 J-T-8-D engines used
on airplanes around the world.
273
00:17:00,686 --> 00:17:04,021
Is there any history of similar
failures?
274
00:17:05,356 --> 00:17:06,942
And it turns out
that Pratt and Whitney
275
00:17:07,067 --> 00:17:09,528
were well aware of the spacer
failures that occurred before.
276
00:17:09,611 --> 00:17:13,198
And so we started to wonder,
what have they done about it?
277
00:17:18,202 --> 00:17:20,163
- It seems to happen a lot.
278
00:17:21,123 --> 00:17:24,250
While researching
spacer issues in other aircraft,
279
00:17:24,375 --> 00:17:28,337
investigators uncover 45 similar
failures
280
00:17:28,422 --> 00:17:31,717
prior to Midwest Express
Flight 1-0-5's accident.
281
00:17:32,675 --> 00:17:34,595
- Well, when we heard
that this part had failed
282
00:17:34,720 --> 00:17:38,432
45 times before, we kind
of looked askance
283
00:17:38,557 --> 00:17:41,934
a bit at the manufacturer.
It's a big deal.
284
00:17:42,810 --> 00:17:44,980
But of all
the failures uncovered
285
00:17:45,105 --> 00:17:46,606
by the NTSB...
286
00:17:47,066 --> 00:17:50,778
- Not a single loss of aircraft
or even a single injury.
287
00:17:51,444 --> 00:17:53,739
- Well, that says something.
288
00:17:53,946 --> 00:17:56,200
...in every
previous incident,
289
00:17:56,282 --> 00:17:57,701
the plane landed safely.
290
00:17:57,785 --> 00:18:00,119
So why did the rupture
of a spacer
291
00:18:00,244 --> 00:18:04,083
on Flight 1-0-5 cause the plane
to become uncontrollable
292
00:18:04,165 --> 00:18:05,584
and crash?
293
00:18:07,461 --> 00:18:09,546
- Well, we knew that none
of the previous failures
294
00:18:09,630 --> 00:18:12,965
had led to an accident,
so one of the questions was:
295
00:18:13,092 --> 00:18:14,259
"What made this one different?"
296
00:18:14,384 --> 00:18:16,970
- Let's see what got hit.
297
00:18:17,971 --> 00:18:20,807
Investigators
consider the possibility
298
00:18:20,932 --> 00:18:24,310
that pieces of the ruptured
spacer on Flight 1-0-5
299
00:18:24,435 --> 00:18:27,730
punctured the plane's fuselage
and damaged vital
300
00:18:27,815 --> 00:18:31,567
control systems such as cables
or hydraulic lines.
301
00:18:32,693 --> 00:18:37,574
When a part like
a spacer or a fan disc breaks
302
00:18:37,657 --> 00:18:40,536
under a lot of stress it's...
303
00:18:40,661 --> 00:18:43,747
it's almost like a small
explosion going off.
304
00:18:43,830 --> 00:18:47,960
You have fragments of metal
flying at very, very
305
00:18:48,042 --> 00:18:49,044
high speeds.
306
00:18:50,170 --> 00:18:52,798
- OK, let's see 8 9 4.
307
00:18:54,258 --> 00:18:57,426
They study
the location and pattern of all
308
00:18:57,510 --> 00:18:59,680
the puncture marks found
on the skin of the plane
309
00:18:59,805 --> 00:19:02,891
to see if any were near vital
control links.
310
00:19:03,851 --> 00:19:06,019
- No control cables.
No hydraulics.
311
00:19:09,897 --> 00:19:10,982
10, 12.
312
00:19:15,945 --> 00:19:18,030
No control cables,
no hydraulics.
313
00:19:20,867 --> 00:19:22,536
What about the pieces
of the plane
314
00:19:22,661 --> 00:19:24,037
that we haven't
been able to find?
315
00:19:25,247 --> 00:19:26,999
There are many
critical pieces of the plane
316
00:19:27,124 --> 00:19:31,752
that have not been recovered
or are too badly damaged
to study.
317
00:19:33,005 --> 00:19:36,008
- Is it possible to figure out
if they could have been hit
318
00:19:36,090 --> 00:19:37,425
by the engine pieces?
319
00:19:38,719 --> 00:19:41,805
- We have what we need to run
a trajectory analysis.
320
00:19:43,222 --> 00:19:44,391
- Alright.
321
00:19:45,017 --> 00:19:47,519
- We were looking at could
these parts
322
00:19:47,603 --> 00:19:51,440
that have left the engine, uh,
strike a control surface,
323
00:19:51,565 --> 00:19:55,443
or the hydraulic system
or anything else
324
00:19:55,568 --> 00:19:57,278
where they could have done
secondary damage
325
00:19:57,403 --> 00:20:00,031
that would have compounded
the situation
326
00:20:00,115 --> 00:20:01,032
the pilots were facing.
327
00:20:01,950 --> 00:20:04,869
Knowing the plane's
velocity, angle of ascent,
328
00:20:04,952 --> 00:20:07,914
and the wind speed at the time
the engine failed,
329
00:20:08,039 --> 00:20:11,500
the team calculates the path
of debris ejected
330
00:20:11,585 --> 00:20:12,877
from the engine.
331
00:20:13,921 --> 00:20:17,007
- The smallest piece we found
was about half an ounce.
332
00:20:17,924 --> 00:20:19,759
The largest piece was just over
a pound.
333
00:20:19,884 --> 00:20:23,305
- So everything moves away from
the plane. Nothing hits it.
334
00:20:24,388 --> 00:20:27,099
The trajectory
analysis tells investigators
335
00:20:27,226 --> 00:20:30,144
that none of the ejected engine
pieces would have struck
336
00:20:30,269 --> 00:20:34,066
the airplane with enough force
to cause substantial damage
337
00:20:34,148 --> 00:20:35,733
to the control systems.
338
00:20:36,609 --> 00:20:40,739
- The analysis indicated that
it was so unlikely
339
00:20:40,821 --> 00:20:43,825
that we considered
it an impossibility,
340
00:20:43,951 --> 00:20:46,869
that those parts leaving
the engine in the direction
341
00:20:46,953 --> 00:20:50,665
they went and the size that
they had could have caused
342
00:20:50,790 --> 00:20:53,292
secondary damage that would
cause loss of control.
343
00:20:55,045 --> 00:20:57,923
If spacer fragments
didn't hit vital components
344
00:20:58,006 --> 00:20:59,840
and cause the loss of control,
345
00:20:59,967 --> 00:21:04,011
perhaps the initial explosive
force opened the cowling,
346
00:21:04,136 --> 00:21:08,182
or engine cover, affecting
the plane's aerodynamics.
347
00:21:09,058 --> 00:21:12,604
- If the cowling had been blown
open, it would cause
348
00:21:12,729 --> 00:21:16,066
a lot of drag. It might cause
the airplane to roll.
349
00:21:16,148 --> 00:21:19,736
It might cause the airplane
to become uncontrollable.
350
00:21:20,569 --> 00:21:22,780
- There's a hole in the cowling.
351
00:21:22,864 --> 00:21:24,281
It looks to be about
2 square inches.
352
00:21:25,157 --> 00:21:27,493
The team finds
evidence that the cowling
353
00:21:27,618 --> 00:21:30,913
was pierced by fragments ejected
from the engine.
354
00:21:32,332 --> 00:21:37,921
- But all four latches, 1, 2,
3, 4, they're all latched.
355
00:21:38,005 --> 00:21:39,673
- It can't have opened
in flight.
356
00:21:41,967 --> 00:21:45,470
- They found them all either
latched or fully intact
357
00:21:45,554 --> 00:21:46,846
with no damage at all.
358
00:21:46,971 --> 00:21:49,307
So that scenario kind of went
out the window.
359
00:21:51,601 --> 00:21:54,104
- So the ruptured right engine
didn't bring down this plane.
360
00:21:54,186 --> 00:21:55,646
- It did not.
361
00:21:59,317 --> 00:22:01,193
Reasonably early
in the investigation
362
00:22:01,318 --> 00:22:03,779
the team figured out that
a spacer had failed
363
00:22:03,864 --> 00:22:05,824
and the engine had failed.
364
00:22:05,906 --> 00:22:08,576
And now we had the rest
of the accident to figure out.
365
00:22:08,701 --> 00:22:11,371
Why would that cause a crash?
366
00:22:17,752 --> 00:22:20,838
Flight 1-0-5's flight data
ex recorder in hopes
367
00:22:20,922 --> 00:22:23,842
of understanding how the loss
of the right engine
368
00:22:23,967 --> 00:22:26,303
caused the death of 31 people.
369
00:22:27,179 --> 00:22:28,430
- It doesn't give us much,
370
00:22:28,555 --> 00:22:30,307
but it's all we've got
to work with.
371
00:22:30,390 --> 00:22:31,974
It was only
recording
372
00:22:32,058 --> 00:22:33,602
four flight parameters.
373
00:22:33,727 --> 00:22:37,105
It had airspeed, altitude,
uh, heading
374
00:22:37,230 --> 00:22:38,898
and vertical acceleration.
375
00:22:40,192 --> 00:22:41,358
- Right here.
376
00:22:41,442 --> 00:22:43,778
A sudden deceleration
at 450 feet.
377
00:22:43,903 --> 00:22:45,696
This must be where
the right engine failed.
378
00:22:45,821 --> 00:22:48,700
- Well, that's consistent with
what the witnesses told us.
379
00:22:50,576 --> 00:22:53,997
The engine failure
we know occurred
380
00:22:54,080 --> 00:22:56,040
above the airport,
so the airplane
381
00:22:56,165 --> 00:22:58,085
had only been airborne
for a few seconds.
382
00:22:58,210 --> 00:23:03,714
- But their heading doesn't
change when the engine fails.
383
00:23:03,798 --> 00:23:07,094
They must be applying left
rudder to compensate.
384
00:23:07,219 --> 00:23:10,596
- Dead right engine, left
rudder. That's the right move.
385
00:23:13,432 --> 00:23:15,059
When the right
engine fails,
386
00:23:15,184 --> 00:23:18,771
the remaining engine should
force the plane to the right.
387
00:23:18,896 --> 00:23:22,526
To counteract that, a pilot
would apply left rudder
388
00:23:22,608 --> 00:23:24,611
to keep the plane flying
straight.
389
00:23:31,410 --> 00:23:32,701
- What the hell was that?
390
00:23:33,327 --> 00:23:35,288
The data shows
that's precisely
391
00:23:35,413 --> 00:23:37,249
what Captain Martin did
in response
392
00:23:37,332 --> 00:23:39,960
to Flight 105's engine failure.
393
00:23:40,460 --> 00:23:41,586
After
a few seconds,
394
00:23:41,670 --> 00:23:43,212
they start this yaw
to the right.
395
00:23:43,296 --> 00:23:45,589
- So, right rudder?
396
00:23:47,217 --> 00:23:50,095
Four seconds after
the failure of the right engine,
397
00:23:50,220 --> 00:23:54,391
the FDR data indicates that
the pilot moved the rudder
398
00:23:54,473 --> 00:23:56,601
from left to right.
399
00:23:56,684 --> 00:23:59,980
That forced the plane into
a sudden yaw to the right.
400
00:24:03,066 --> 00:24:04,733
- He's in a sideslip.
401
00:24:04,817 --> 00:24:08,113
And he's deviating further
and further to the right.
402
00:24:10,198 --> 00:24:12,325
And then he starts to lose
altitude.
403
00:24:13,492 --> 00:24:15,452
148 knots.
404
00:24:16,704 --> 00:24:18,457
He's in a high-speed stall.
405
00:24:20,291 --> 00:24:21,750
- How'd they let that happen?
406
00:24:23,545 --> 00:24:27,132
He went into
a right skid, and then followed
407
00:24:27,257 --> 00:24:29,509
by an abrupt right turn
and dive.
408
00:24:29,634 --> 00:24:31,678
That would be consistent
with a stall.
409
00:24:31,803 --> 00:24:35,515
But the airspeeds indicated
were high enough
410
00:24:35,640 --> 00:24:39,059
that you wouldn't normally
have a stall at those speeds.
411
00:24:40,103 --> 00:24:42,230
- They've clearly lost control
of the plane.
412
00:24:42,355 --> 00:24:44,398
Five seconds later,
they hit the ground.
413
00:24:46,942 --> 00:24:49,778
The flight data
tells investigators that it took
414
00:24:49,863 --> 00:24:53,657
only 10 seconds for the pilots
to lose control of the plane
415
00:24:53,782 --> 00:24:56,577
after the failure
of the right engine.
416
00:24:58,872 --> 00:25:01,333
I have never
seen an accident sequence
417
00:25:01,415 --> 00:25:05,586
that brief, um, before or since.
418
00:25:08,673 --> 00:25:12,219
- So, he responds correctly
at first with left rudder
419
00:25:12,344 --> 00:25:13,595
and nose down pitch.
420
00:25:13,720 --> 00:25:16,932
Then he inexplicably switches
to right rudder?
421
00:25:17,057 --> 00:25:18,599
- And that's what leads
to the yaw,
422
00:25:18,724 --> 00:25:20,684
the right roll
and the eventual stall.
423
00:25:20,809 --> 00:25:23,520
- Right rudder. It makes
no sense.
424
00:25:24,689 --> 00:25:27,025
- It was clear,
from all the data,
425
00:25:27,107 --> 00:25:28,943
that the pilot didn't understand
what happened.
426
00:25:29,068 --> 00:25:32,739
He responded inappropriately,
and within seconds,
427
00:25:32,864 --> 00:25:35,032
the airplane was lost,
and everybody on board
428
00:25:35,157 --> 00:25:36,535
was killed in the accident.
429
00:25:37,661 --> 00:25:41,705
Was there something
about the DC-9's handling
characteristics
430
00:25:41,789 --> 00:25:44,792
that led the pilots to input
the right rudder?
431
00:25:44,917 --> 00:25:48,046
- So, it was relatively
easy to control then?
432
00:25:49,088 --> 00:25:52,925
Just with the control wheel?
433
00:25:54,219 --> 00:25:57,055
Investigators
interview DC-9 pilots
434
00:25:57,180 --> 00:26:00,808
to determine how the plane
handles with only one engine.
435
00:26:00,933 --> 00:26:03,811
- The DC-9 pilots that we talked
to, it was overwhelmingly
436
00:26:03,936 --> 00:26:06,815
described as a very easy,
docile aircraft
437
00:26:06,940 --> 00:26:08,732
to handle in those situations.
438
00:26:08,817 --> 00:26:12,903
- Oh, this has been extremely
helpful. Thanks. OK. Bye.
439
00:26:14,864 --> 00:26:16,575
They all say the same thing.
440
00:26:16,700 --> 00:26:18,910
It's no big deal with
one engine.
441
00:26:21,162 --> 00:26:23,957
Because the DC-9's
engines are mounted
442
00:26:24,082 --> 00:26:26,166
on the fuselage instead
of the wings,
443
00:26:26,292 --> 00:26:29,378
when one engine fails
it does not force the plane
444
00:26:29,461 --> 00:26:30,797
into a severe turn.
445
00:26:30,922 --> 00:26:34,425
- The DC-9 is almost
a centerline thrust aircraft.
446
00:26:34,509 --> 00:26:37,721
So if you lose one engine
on either side,
447
00:26:37,804 --> 00:26:41,932
there's not that much excess
yawing
448
00:26:42,017 --> 00:26:44,644
or controllability
problems at all.
449
00:26:46,895 --> 00:26:49,106
How easy is
it to handle a DC-9
450
00:26:49,190 --> 00:26:52,027
in the situation the pilots
of Flight 1-0-5
451
00:26:52,152 --> 00:26:53,944
found themselves in?
452
00:26:54,863 --> 00:26:59,159
- It was valuable to do
a simulation or test flight,
453
00:26:59,284 --> 00:27:03,704
to get a better idea of exactly
how the airplane performed
454
00:27:03,829 --> 00:27:06,540
under the circumstances
of the accident
455
00:27:06,665 --> 00:27:08,585
but at a higher altitude.
456
00:27:11,337 --> 00:27:14,132
- OK, when we get to 10 000
feet I'm going to cut power
457
00:27:14,257 --> 00:27:16,634
to the right leaving the left
at takeoff power.
458
00:27:16,759 --> 00:27:20,512
Keep the flaps at 20.
Target speed is 170 knots.
459
00:27:22,015 --> 00:27:23,642
They tried
to match the parameters
460
00:27:23,767 --> 00:27:26,810
of the airplane in terms
of the flaps, gear, uh...
461
00:27:26,935 --> 00:27:32,733
and airspeed and then proceeded
to cut the engine power.
462
00:27:34,527 --> 00:27:36,488
- OK, cutting power.
463
00:27:45,246 --> 00:27:48,665
OK, thank you.
Let's go around for another.
464
00:27:50,376 --> 00:27:52,127
The flight
demonstrations showed that
465
00:27:52,211 --> 00:27:55,423
the pilot didn't have
to input rudder at all.
466
00:27:55,548 --> 00:27:57,800
If he had only used
the ailerons,
467
00:27:57,884 --> 00:27:59,385
he could have safely
flown out of it.
468
00:28:00,553 --> 00:28:04,682
- OK, this time no reaction.
Let's see what the plane does.
469
00:28:06,058 --> 00:28:08,811
With no input from
the pilot after the loss
470
00:28:08,894 --> 00:28:13,982
of the right engine, the plane
rolls right and the nose drops.
471
00:28:16,736 --> 00:28:19,196
- OK, you can recover?
472
00:28:21,115 --> 00:28:23,201
Even with
no immediate action,
473
00:28:23,284 --> 00:28:26,203
the pilot is easily able
to recover the plane.
474
00:28:28,414 --> 00:28:32,042
- OK, I think we have
what we need.
475
00:28:32,126 --> 00:28:35,838
- That may have actually been
the best thing to do was...
476
00:28:35,922 --> 00:28:39,217
was to do nothing, watch
the airplane's response,
477
00:28:39,342 --> 00:28:40,884
understand the airplane's
response
478
00:28:40,969 --> 00:28:43,346
and respond appropriately
to the nature of the emergency.
479
00:28:47,433 --> 00:28:48,934
- What the hell was that?
480
00:28:50,019 --> 00:28:53,064
If the DC-9
is so easy to control,
481
00:28:53,189 --> 00:28:57,067
why were two experienced pilots
unable to recover
482
00:28:57,152 --> 00:28:59,362
from the loss
of their right engine?
483
00:29:03,575 --> 00:29:06,869
- OK, we kpt with the airline.
484
00:29:06,952 --> 00:29:08,997
But how much experience
did they actually have?
485
00:29:09,580 --> 00:29:11,624
Investigators look
into the backgrounds
486
00:29:11,750 --> 00:29:14,794
of the pilots of Midwest Express
Flight 1-0-5
487
00:29:14,919 --> 00:29:17,838
to understand why they didn't
recover from
488
00:29:17,963 --> 00:29:19,257
a single-engine failure.
489
00:29:19,339 --> 00:29:21,634
- Neither had a lot of turbo
jet experience.
490
00:29:22,259 --> 00:29:24,929
One was
upgraded to captain
491
00:29:25,012 --> 00:29:27,598
with 600 hours on the DC-9,
the other with only 500.
492
00:29:27,682 --> 00:29:30,268
- It doesn't seem like
a whole lot.
493
00:29:31,478 --> 00:29:33,605
- Advancement to captain
happened within a year
494
00:29:33,730 --> 00:29:38,067
for both of these pilots,
at Midwest Express Airlines
495
00:29:38,151 --> 00:29:39,652
at that time.
496
00:29:39,778 --> 00:29:42,779
And the reason why was it was
a small airline.
497
00:29:42,864 --> 00:29:46,617
It was growing quickly.
They were adding airplanes.
498
00:29:48,327 --> 00:29:51,330
They consult large US airlines
to determine
499
00:29:51,455 --> 00:29:53,625
their qualifications
for an upgrade.
500
00:29:54,959 --> 00:29:56,586
- Ok. Thanks.
501
00:29:58,086 --> 00:30:02,133
- It's the same for both
airlines: 10 years seniority
502
00:30:02,217 --> 00:30:05,094
and 75-hundred hours as DC-9
first officer
503
00:30:05,178 --> 00:30:06,304
to be considered for an upgrade.
504
00:30:07,012 --> 00:30:09,307
- You know, these guys weren't
anywhere near that.
505
00:30:10,724 --> 00:30:12,684
While the pilots may
have been experienced,
506
00:30:12,809 --> 00:30:16,230
neither had spent much time
piloting the DC-9
507
00:30:16,355 --> 00:30:18,023
before they were promoted
to captain.
508
00:30:18,857 --> 00:30:20,442
The more
experience someone has
509
00:30:20,527 --> 00:30:24,655
exercising command, the more
likely they are to exercise
510
00:30:24,780 --> 00:30:27,991
that command in situations
that call for calm thinking,
511
00:30:28,076 --> 00:30:30,327
for rational response and so on.
512
00:30:32,038 --> 00:30:35,500
- So how much training did these
guys get on engine failures?
513
00:30:36,709 --> 00:30:39,753
To understand why
the pilots of Flight 1-0-5
514
00:30:39,878 --> 00:30:41,673
were not able to control
their plane
515
00:30:41,798 --> 00:30:43,549
following an engine failure,
516
00:30:43,674 --> 00:30:45,844
investigators look
at their training records.
517
00:30:46,678 --> 00:30:48,680
What was
their experience?
518
00:30:48,805 --> 00:30:50,181
What kind of pilots were they?
519
00:30:50,306 --> 00:30:53,518
How did they respond to unusual
events?
520
00:30:53,601 --> 00:30:57,105
Did they seem self-confident?
How well did they work together?
521
00:30:58,855 --> 00:31:05,153
- OK, so the captain's practiced
12 engine failures
522
00:31:05,238 --> 00:31:11,368
on takeoff in the simulator.
The first officer, 15 sessions.
523
00:31:12,077 --> 00:31:13,704
They discover
that both pilots
524
00:31:13,829 --> 00:31:16,915
had been extensively trained
to cope with engine failure
525
00:31:17,040 --> 00:31:18,375
on take-off...
526
00:31:19,460 --> 00:31:21,712
- It's precisely the type
of emergency they faced
527
00:31:21,796 --> 00:31:22,713
on Flight 1-0-5.
528
00:31:23,548 --> 00:31:26,049
...but what
exactly were they taught?
529
00:31:27,719 --> 00:31:30,555
- We looked very closely
at the training these pilots
530
00:31:30,680 --> 00:31:33,724
received and interviewed
the flight instructor
531
00:31:33,849 --> 00:31:37,561
who oversaw their training
in the DC-9 for Midwest Express.
532
00:31:38,895 --> 00:31:43,108
- Tell me what you can remember
about captains Martin and Weiss.
533
00:31:45,987 --> 00:31:49,824
- They were both excellent
pilots, trained to proficiency.
534
00:31:51,451 --> 00:31:54,119
- Lots of simulator training
on engine failure.
535
00:31:54,244 --> 00:31:58,540
- You bet. We ran them through
all sorts of scenarios.
536
00:32:00,167 --> 00:32:04,923
- Let's focus on takeoff
with simulated engine failure.
537
00:32:05,048 --> 00:32:06,590
What were they taught?
538
00:32:11,762 --> 00:32:13,847
- Pay attention to your yaw.
It's your best cue.
539
00:32:16,683 --> 00:32:19,519
Yawing right.
Applying left rudder.
540
00:32:20,605 --> 00:32:23,273
- Control wheel as needed.
Keep the plane level.
541
00:32:23,357 --> 00:32:27,236
Nice and easy.
That's a good job.
542
00:32:27,319 --> 00:32:28,904
- Got it.
543
00:32:29,905 --> 00:32:32,616
Captain Martin was
trained to pay close attention
544
00:32:32,700 --> 00:32:35,452
to the plane's yawing motion
when identifying
545
00:32:35,536 --> 00:32:37,288
and correcting
an engine failure.
546
00:32:38,038 --> 00:32:40,500
- It looks like they had
excellent training.
547
00:32:40,625 --> 00:32:42,460
Thanks for the insight.
548
00:32:45,672 --> 00:32:47,464
We found
the instructor,
549
00:32:47,548 --> 00:32:50,509
uh, to be very capable,
very dedicated,
550
00:32:50,634 --> 00:32:53,261
and we found the simulators
to be... to be okay,
551
00:32:53,346 --> 00:32:56,432
uh, for that time.
552
00:32:57,307 --> 00:33:00,478
If Captain Martin
was extensively trained to cope
553
00:33:00,560 --> 00:33:02,105
with engine failure on take-off,
554
00:33:02,188 --> 00:33:05,107
why didn't he do
what he was trained to do.
555
00:33:08,861 --> 00:33:12,573
- Most of their training was for
an engine failure at take-off.
556
00:33:12,699 --> 00:33:15,159
Pretty easy to identify
which way you're yawing.
557
00:33:15,284 --> 00:33:16,243
Yeah.
558
00:33:16,368 --> 00:33:18,371
- Investigators consider
the timing
559
00:33:18,496 --> 00:33:19,705
of the engine failure.
560
00:33:19,830 --> 00:33:21,164
If you're
closer to the ground,
561
00:33:21,289 --> 00:33:24,460
there are much more visual cues
available from the ground
562
00:33:24,544 --> 00:33:26,671
to see what the airplane
is encountering.
563
00:33:28,131 --> 00:33:30,133
Not so easy
when you're already
564
00:33:30,215 --> 00:33:31,759
in a steep climb.
565
00:33:31,884 --> 00:33:32,884
- Right.
566
00:33:34,053 --> 00:33:37,848
As Flight 1-0-5 was
climbing, only blue sky
567
00:33:37,973 --> 00:33:39,808
would have been visible
to the pilots,
568
00:33:39,892 --> 00:33:42,103
making it more difficult
to identify
569
00:33:42,228 --> 00:33:44,105
the direction of the yaw.
570
00:33:47,567 --> 00:33:49,067
- What the hell was that?
571
00:33:50,111 --> 00:33:51,738
With no outside
visual cues,
572
00:33:51,863 --> 00:33:55,240
investigators believe Captain
Martin's initial response
573
00:33:55,365 --> 00:33:58,869
was a spontaneous reaction
to the plane's changing motion
574
00:33:58,952 --> 00:34:02,330
and not the result
of an analysis of the situation.
575
00:34:02,414 --> 00:34:05,667
But what triggered the incorrect
rudder application
576
00:34:05,751 --> 00:34:07,045
a few seconds later,
577
00:34:07,127 --> 00:34:09,922
that resulted in a total
loss of control?
578
00:34:11,673 --> 00:34:13,967
- Alright, let's see what
these guys were doing.
579
00:34:19,347 --> 00:34:22,226
Midex
1-0-5, cleared for takeoff.
580
00:34:22,351 --> 00:34:23,894
Midex 1-0-5.
581
00:34:23,978 --> 00:34:26,271
Here we go.
582
00:34:29,275 --> 00:34:32,027
Investigators pin
their hopes on the CVR
583
00:34:32,110 --> 00:34:34,864
to explain Captain Martin's
actions.
584
00:34:36,699 --> 00:34:38,117
Spooling up.
585
00:34:38,617 --> 00:34:39,869
Power normal.
586
00:34:42,538 --> 00:34:43,956
100.
587
00:34:48,293 --> 00:34:50,213
V-1. Rotate.
588
00:34:53,800 --> 00:34:54,967
Gear up.
589
00:34:59,806 --> 00:35:01,056
- The spacer?
590
00:35:01,139 --> 00:35:02,224
(controller on CVR:
Midex 1-0-5,
591
00:35:02,307 --> 00:35:04,059
turn left heading 1-7-5.
592
00:35:04,143 --> 00:35:06,521
What have we got here, Bill?
593
00:35:06,646 --> 00:35:07,480
Here!
594
00:35:08,271 --> 00:35:11,483
Midex 1-0-5 roger,
595
00:35:11,608 --> 00:35:12,985
ah we got an emergency here.
596
00:35:14,987 --> 00:35:16,447
Midex 1-0-5 roger.
597
00:35:16,572 --> 00:35:18,032
Oh crap.
598
00:35:19,117 --> 00:35:21,077
Get your heads down. Heads down!
599
00:35:27,875 --> 00:35:30,670
- I've never heard an accident
unfold so quickly.
600
00:35:30,795 --> 00:35:32,672
Holy smokes.
601
00:35:33,338 --> 00:35:36,007
And I remember
just being amazed
602
00:35:36,134 --> 00:35:38,552
how quickly the accident
took place.
603
00:35:38,677 --> 00:35:41,179
It was like they're...
they were flying.
604
00:35:41,304 --> 00:35:43,349
You hear the engine fail,
605
00:35:43,474 --> 00:35:46,811
uh, and the next thing you know,
the airplane's lost.
606
00:35:48,813 --> 00:35:51,731
- OK, so what did we hear?
607
00:35:52,275 --> 00:35:53,358
- It sure happened fast.
608
00:35:53,483 --> 00:35:56,820
- Yup, 15 seconds from the sound
of the engine exploding
609
00:35:56,945 --> 00:35:58,405
to the end of the recording.
610
00:35:58,530 --> 00:36:00,282
Astonishing.
611
00:36:05,538 --> 00:36:06,831
What else?
612
00:36:06,956 --> 00:36:09,666
- "What was that?
What have we got?"
613
00:36:09,791 --> 00:36:13,045
The captain seemed uncertain.
614
00:36:13,170 --> 00:36:14,713
- Agreed.
615
00:36:18,885 --> 00:36:20,177
- What have we got here, Bill?
616
00:36:21,429 --> 00:36:24,681
- Well, it was clear from
the cockpit voice recorder
617
00:36:24,764 --> 00:36:28,143
that the pilot didn't recognize
what had happened.
618
00:36:28,226 --> 00:36:29,186
He articulates that.
619
00:36:29,311 --> 00:36:32,106
"What was that? What have we got
here, Bill?"
620
00:36:34,858 --> 00:36:36,277
- What the hell was that?
621
00:36:36,902 --> 00:36:38,153
The sound
of the engine,
622
00:36:38,237 --> 00:36:41,489
the sensation of the right yaw,
and the instruments
623
00:36:41,574 --> 00:36:44,577
should have told Captain Martin
that he was dealing
624
00:36:44,702 --> 00:36:47,038
with a failure of his
right engine.
625
00:36:48,914 --> 00:36:50,666
- Anything else on that tape?
626
00:36:51,416 --> 00:36:54,670
- Not a lot of troubleshooting
or communication
627
00:36:54,753 --> 00:36:56,297
between them really.
628
00:36:57,380 --> 00:37:00,425
- Actually none.
629
00:37:06,181 --> 00:37:10,018
- What have we got here, Bill?
Here!
630
00:37:10,853 --> 00:37:15,650
- Midex 1-0-5 roger,
ah we got an emergency here.
631
00:37:16,400 --> 00:37:18,235
Investigators hear
Captain Martin
632
00:37:18,360 --> 00:37:22,030
asking his first officer
for assistance in assessing
the situation,
633
00:37:22,114 --> 00:37:24,867
but First Officer Weiss
never replies.
634
00:37:25,701 --> 00:37:30,748
- That was troubling to me
because I would have expected
635
00:37:30,831 --> 00:37:33,918
that in an emergency situation
and especially
636
00:37:34,001 --> 00:37:38,588
when asked for help, that
the other crew member
637
00:37:38,672 --> 00:37:40,132
would have helped if he could.
638
00:37:41,007 --> 00:37:45,012
So that prompted some further
investigation.
639
00:37:46,429 --> 00:37:50,351
- OK, let's start with that:
Why was the Captain confused
640
00:37:50,476 --> 00:37:51,393
about what had happened?
641
00:37:51,476 --> 00:37:53,228
- It should have been obvious.
642
00:37:56,898 --> 00:37:58,693
46-hundred flight hours:
643
00:37:58,818 --> 00:38:01,070
but he's never experienced
an actual engine failure.
644
00:38:01,570 --> 00:38:03,947
NTSB Investigators
looking into the crash
645
00:38:04,030 --> 00:38:07,117
of Midwest Express Flight 1-0-5
have learned that
646
00:38:07,242 --> 00:38:09,411
Captain Martin's only
experience
647
00:38:09,494 --> 00:38:12,289
with a single-engine
failure was in a simulator.
648
00:38:12,873 --> 00:38:15,458
- Yaw and deceleration don't
feel the same,
649
00:38:15,543 --> 00:38:16,793
plus all the sounds
are different.
650
00:38:16,918 --> 00:38:18,963
- It's not the same as
the real thing.
651
00:38:19,755 --> 00:38:21,673
- It was a catastrophic engine
failure where they had thrust
652
00:38:21,798 --> 00:38:24,677
and then they didn't.
It was immediate. Uh...
653
00:38:24,802 --> 00:38:28,931
I don't think they were trained
in that kind of scenario.
654
00:38:29,724 --> 00:38:31,391
- What have we got here, Bill?
655
00:38:32,684 --> 00:38:34,853
The limitations
of the simulator may explain
656
00:38:34,978 --> 00:38:36,896
Captain Martin's initial
confusion,
657
00:38:37,023 --> 00:38:41,110
but it does not explain
the first officer's
unusual silence.
658
00:38:42,820 --> 00:38:44,447
- Let's have another listen.
659
00:38:46,364 --> 00:38:48,867
They return
to the cockpit voice recording
660
00:38:48,992 --> 00:38:52,204
to better understand how
First Officer Weiss
661
00:38:52,329 --> 00:38:53,914
reacted to the emergency.
662
00:38:57,208 --> 00:38:58,753
What the hell was that?
663
00:38:58,878 --> 00:38:59,836
- That's one.
664
00:38:59,961 --> 00:39:01,088
Midex 1-0-5,
665
00:39:01,213 --> 00:39:02,672
turn left heading 1-7-5.
666
00:39:02,757 --> 00:39:04,632
What have we got here, Bill?
667
00:39:04,717 --> 00:39:06,427
- That's two.
- Here!
668
00:39:06,552 --> 00:39:07,844
- That's three.
669
00:39:11,222 --> 00:39:12,849
He asks for help three times,
670
00:39:12,974 --> 00:39:15,436
but the FO says absolutely
nothing to him the entire time.
671
00:39:15,561 --> 00:39:18,773
- Not even "I'm not sure,"
or "I don't know."
672
00:39:18,898 --> 00:39:20,190
Not a word.
673
00:39:21,067 --> 00:39:24,027
- In this situation,
seconds were critical.
674
00:39:24,110 --> 00:39:28,574
Had he said right away,
"I don't know," then the captain
675
00:39:28,699 --> 00:39:31,577
would immediately have tried
to rely on his own understanding
676
00:39:31,702 --> 00:39:34,621
of the situation, rather than
expect the first officer
677
00:39:34,746 --> 00:39:36,956
to come up with an explanation
of what he had.
678
00:39:39,085 --> 00:39:42,463
What could have
caused the first officer's
silence?
679
00:39:44,422 --> 00:39:49,637
- Hang on. What altitude where
they at when the engine failed?
680
00:39:52,056 --> 00:39:53,306
- 450 feet.
681
00:39:53,766 --> 00:39:55,976
- This could be it then.
682
00:39:56,101 --> 00:39:58,436
Pilots say they were taught
not to make callouts
683
00:39:58,561 --> 00:40:01,481
or even verbalize the nature
of an emergency
684
00:40:01,606 --> 00:40:05,485
after 100 knots, before
reaching 800 feet.
685
00:40:06,402 --> 00:40:07,612
- Let me see.
686
00:40:14,702 --> 00:40:16,831
Not even to identify
a failed engine.
687
00:40:16,956 --> 00:40:20,251
No communication at all
until 800 feet.
688
00:40:21,918 --> 00:40:24,380
I couldn't imagine
a management team
689
00:40:24,463 --> 00:40:29,092
at Midwest Express thinking
this silent cockpit business
690
00:40:29,175 --> 00:40:31,094
made any sense.
691
00:40:31,219 --> 00:40:34,974
It just flies in the face
of communication,
692
00:40:35,099 --> 00:40:38,811
which is kind of the fabric that
holds a safe flight together.
693
00:40:38,936 --> 00:40:42,148
So it just blew my mind,
frankly.
694
00:40:46,818 --> 00:40:49,447
- What the hell was that?
695
00:40:49,864 --> 00:40:51,824
Investigators think
First Officer Weiss
696
00:40:51,949 --> 00:40:55,034
may have been following
a Midwest Express unwritten rule
697
00:40:55,161 --> 00:40:59,664
of not discussing emergencies
until the plane reaches
800 feet.
698
00:40:59,789 --> 00:41:02,083
It's important
during an emergency
699
00:41:02,168 --> 00:41:06,297
for people to talk to each other
because they both may not be
700
00:41:06,422 --> 00:41:08,047
looking at the same instrument.
701
00:41:08,173 --> 00:41:10,759
They both may not be looking
at the same thing outside.
702
00:41:10,842 --> 00:41:13,137
You have to talk.
You have to talk.
703
00:41:13,971 --> 00:41:17,141
One last thing
troubles investigators.
704
00:41:17,266 --> 00:41:20,226
In spite of his first officer's
silence, Captain Martin
705
00:41:20,351 --> 00:41:23,188
could have easily identified
which engine had failed
706
00:41:23,313 --> 00:41:25,190
simply by looking
at his instruments.
707
00:41:25,900 --> 00:41:28,443
Both pilots
had visual information
708
00:41:28,527 --> 00:41:29,737
from the engine flight
instruments,
709
00:41:29,862 --> 00:41:31,780
the bank turn indicator
and so on,
710
00:41:31,864 --> 00:41:34,909
that would have told
them um...
711
00:41:35,034 --> 00:41:37,202
what was going on in terms
of the loss of thrust.
712
00:41:39,038 --> 00:41:41,498
- I don't think either of them
were scanning the instruments.
713
00:41:41,623 --> 00:41:43,000
- Agreed.
714
00:41:43,083 --> 00:41:44,376
They never saw which engine
had failed,
715
00:41:44,501 --> 00:41:47,338
the direction of the yaw
or the severity of the roll.
716
00:41:48,922 --> 00:41:51,842
The NTSB concludes
that the pilots' failure
717
00:41:51,967 --> 00:41:54,677
to monitor their instruments
contributed to Captain Martin's
718
00:41:54,802 --> 00:41:57,014
incorrect rudder application.
719
00:41:57,139 --> 00:41:59,391
With the lack
of visual cues,
720
00:41:59,516 --> 00:42:02,061
the only sure way they would
have had to recognize
721
00:42:02,186 --> 00:42:06,023
which engine failed would
be to look at the instruments.
722
00:42:07,065 --> 00:42:09,943
The pilots' lack of
awareness ultimately led
723
00:42:10,068 --> 00:42:13,030
to the stall that brought down
Flight 1-0-5.
724
00:42:19,411 --> 00:42:21,038
- Up until here he should
be fine.
725
00:42:21,121 --> 00:42:23,541
But then there's no
communication
726
00:42:23,623 --> 00:42:25,291
and no instrument scanning.
727
00:42:26,501 --> 00:42:28,086
And this, this is what
dooms them.
728
00:42:28,211 --> 00:42:31,215
He puts in right rudder,
which sends them
729
00:42:31,297 --> 00:42:36,052
into a sideslip, an extreme
right roll and a stall.
730
00:42:36,637 --> 00:42:38,764
- If they had talked
to each other,
731
00:42:38,889 --> 00:42:42,141
scanned their instruments
you don't get this accident.
732
00:42:44,269 --> 00:42:47,606
- The reality of the situation
is the mismanagement
733
00:42:47,731 --> 00:42:50,943
inside the cockpit caused
the accident,
734
00:42:51,068 --> 00:42:53,237
not the engine failure.
735
00:42:54,112 --> 00:42:56,072
The NTSB's final
report
736
00:42:56,197 --> 00:42:58,367
makes several key
recommendations to prevent
737
00:42:58,449 --> 00:43:00,786
this type of accident
from happening again.
738
00:43:00,911 --> 00:43:04,206
They recommend a directive
requiring airlines
739
00:43:04,289 --> 00:43:07,543
to replace the existing spacers
with a new type of spacer
740
00:43:07,626 --> 00:43:09,378
which is less likely to fail.
741
00:43:10,295 --> 00:43:12,797
They also recommend that
airlines are advised
742
00:43:12,922 --> 00:43:15,092
to teach their pilots
to communicate
743
00:43:15,175 --> 00:43:16,635
during on-board emergencies.
744
00:43:17,635 --> 00:43:20,639
It should never be
overstated the importance
745
00:43:20,764 --> 00:43:21,974
of crew coordination.
746
00:43:22,099 --> 00:43:24,809
Every crew member has something
valuable to add.
747
00:43:24,934 --> 00:43:29,940
Anything that is an abnormality
needs to be discussed
748
00:43:30,733 --> 00:43:32,400
at the proper time.
749
00:43:33,360 --> 00:43:35,570
They also suggest
that airlines review
750
00:43:35,653 --> 00:43:38,782
their simulator training
to ensure pilots are taught
751
00:43:38,907 --> 00:43:41,619
to use their instruments
to assess the nature
752
00:43:41,702 --> 00:43:43,119
of engine failures.
753
00:43:43,202 --> 00:43:47,458
- I think this accident still
has an impact today
754
00:43:47,541 --> 00:43:54,297
because it's such a clear
illustration of what happens
755
00:43:54,422 --> 00:43:58,677
when you don't do what you
should to do in an emergency.
756
00:43:58,802 --> 00:44:00,846
Any time there's an emergency,
757
00:44:00,971 --> 00:44:04,557
you should have the exact
same procedures,
758
00:44:04,682 --> 00:44:06,476
and you should run right
to them.
759
00:44:07,686 --> 00:44:11,440
Midwest Express
Airlines continued to operate
760
00:44:11,523 --> 00:44:12,900
until 2009.
761
00:44:13,025 --> 00:44:16,070
It merged with
Frontier Airlines in 2010.
