1
00:00:10,034 --> 00:00:11,965
<i>They're
the traffic cops of the skies.</i>

2
00:00:16,413 --> 00:00:17,896
<i>Keeping planes on course.</i>

3
00:00:21,275 --> 00:00:23,172
Okay, you're right
in the middle
of the TCA, sir.

4
00:00:23,275 --> 00:00:24,965
<i>Guiding them to safety.</i>

5
00:00:25,068 --> 00:00:27,379
<i>Avianca 052,
look at your TCA chart.</i>

6
00:00:27,482 --> 00:00:29,620
Charlie 2937 descend...

7
00:00:29,724 --> 00:00:31,000
<i>And keeping them apart.</i>

8
00:00:32,413 --> 00:00:34,689
<i>But the system has reached
a breaking point.</i>

9
00:00:34,793 --> 00:00:35,931
Where is it?

10
00:00:36,034 --> 00:00:38,068
CO-PILOT: There! On the left!

11
00:00:44,827 --> 00:00:46,724
<i>If there is another
major airline accident,</i>

12
00:00:46,827 --> 00:00:48,000
it's going to
probably originate

13
00:00:48,103 --> 00:00:49,586
from an air traffic
control problem.

14
00:00:49,689 --> 00:00:51,310
Yup, yup. We got it.

15
00:00:51,413 --> 00:00:52,827
<i>There are
too many planes.</i>

16
00:00:54,931 --> 00:00:57,655
<i>The tools controllers use
to track them are inadequate.</i>

17
00:00:59,793 --> 00:01:02,620
<i>The failing system
is putting passengers at risk.</i>

18
00:01:02,724 --> 00:01:04,068
Monitor, vertical.

19
00:01:04,172 --> 00:01:06,206
<i>Now,
the race is on to fix it...</i>

20
00:01:06,310 --> 00:01:08,000
Do you
see him, Daniel?
No.

21
00:01:08,103 --> 00:01:09,758
<i>...before disaster strikes
again.</i>

22
00:01:15,517 --> 00:01:16,448
Mayday! Mayday!

23
00:01:38,620 --> 00:01:42,172
<i>Rush hour.
John F. Kennedy
International Airport.</i>

24
00:01:43,620 --> 00:01:44,896
<i>One of the busiest
in the world.</i>

25
00:01:47,000 --> 00:01:49,896
<i>More than 1,200 planes
use JFK everyday.</i>

26
00:01:51,310 --> 00:01:53,586
<i>In the sky, they're stacked up
for kilometers,</i>

27
00:01:53,689 --> 00:01:54,827
<i>waiting to land.</i>

28
00:01:56,310 --> 00:01:58,896
<i>On the ground,
dozens more are waiting
to take off.</i>

29
00:02:00,448 --> 00:02:02,172
<i>The constant stream
of airliners</i>

30
00:02:02,275 --> 00:02:03,517
<i>can tax the abilities</i>

31
00:02:03,620 --> 00:02:05,413
<i>of even the most
experienced controllers.</i>

32
00:02:08,655 --> 00:02:09,965
The "picture",
as it's called,

33
00:02:10,068 --> 00:02:11,551
that they have to
maintain in their head

34
00:02:11,655 --> 00:02:13,689
of everything
they're controlling,
where everybody is,

35
00:02:13,793 --> 00:02:16,482
<i>their speed, their altitude,
their separation.</i>

36
00:02:16,586 --> 00:02:19,862
<i>Also includes constant
back and forth
talking to the pilots.</i>

37
00:02:19,965 --> 00:02:23,689
And this is a matrix
of information flow in
and out of their brains.

38
00:02:23,793 --> 00:02:25,551
It's just amazing to watch.

39
00:02:25,655 --> 00:02:28,689
<i>For the team
of air traffic controllers
in JFK'S tower,</i>

40
00:02:29,758 --> 00:02:31,344
<i>it's just another
day at work.</i>

41
00:02:33,000 --> 00:02:34,724
<i>It's a job that gets
more demanding</i>

42
00:02:34,827 --> 00:02:36,172
<i>with each passing year.</i>

43
00:02:37,793 --> 00:02:39,724
<i>On a busy day
in most centers</i>

44
00:02:39,827 --> 00:02:41,965
and most departure
and arrival controllers,

45
00:02:42,068 --> 00:02:43,068
you're saturated.

46
00:02:43,172 --> 00:02:45,068
You've got people talking
as fast as they can.

47
00:02:50,689 --> 00:02:52,172
And that's where
errors come in.

48
00:02:55,379 --> 00:02:56,379
<i>Over the last decade,</i>

49
00:02:56,482 --> 00:03:00,068
<i>there's been a 25% jump
in traffic at JFK.</i>

50
00:03:01,793 --> 00:03:03,655
<i>And New York's not alone.</i>

51
00:03:03,758 --> 00:03:06,620
<i>It's a trend that concerns
some industry experts.</i>

52
00:03:10,379 --> 00:03:12,241
One of the things that I do
as an aviation analyst

53
00:03:12,344 --> 00:03:14,586
is try to keep a good lock
on what's happening,

54
00:03:14,689 --> 00:03:16,827
<i>watch where the weak spots
are in the system.</i>

55
00:03:18,758 --> 00:03:20,620
<i>If there is another major
airline accident,</i>

56
00:03:20,724 --> 00:03:22,758
God forbid, it's going
to probably originate

57
00:03:22,862 --> 00:03:24,000
from an air traffic
control problem.

58
00:03:26,482 --> 00:03:29,965
<i>The solution
to the looming crisis
is being developed here,</i>

59
00:03:30,068 --> 00:03:32,862
<i>The William J. Hughes
Technical Center
in New Jersey.</i>

60
00:03:34,655 --> 00:03:36,034
<i>It's the workshop
of America's</i>

61
00:03:36,137 --> 00:03:37,827
<i>Federal Aviation
Administration.</i>

62
00:03:39,931 --> 00:03:43,896
The center has been involved
in every major advance

63
00:03:44,000 --> 00:03:48,344
in air transportation
system technology since 1958.

64
00:03:48,448 --> 00:03:52,310
<i>Airport design, aircraft
safety and security...</i>

65
00:03:55,310 --> 00:03:57,965
<i>communications, navigation.</i>

66
00:03:58,068 --> 00:04:00,000
<i>Scientists at
the William Hughes Center</i>

67
00:04:00,103 --> 00:04:02,689
<i>have tackled aviation's
most difficult problems.</i>

68
00:04:04,827 --> 00:04:06,655
<i>Today, this plane is
at the heart</i>

69
00:04:06,758 --> 00:04:09,551
<i>of one of the largest projects
in the history of the FAA.</i>

70
00:04:11,000 --> 00:04:13,689
<i>They're using it to design
a new air traffic system</i>

71
00:04:13,793 --> 00:04:16,034
<i>that will help manage
more traffic safely.</i>

72
00:04:21,896 --> 00:04:23,793
<i>A two or threefold
increase in the number</i>

73
00:04:23,896 --> 00:04:27,000
of aircraft flying is
certainly within the, uh...

74
00:04:27,103 --> 00:04:28,551
within the range
of possibility

75
00:04:28,655 --> 00:04:30,827
<i>in the next couple of decades.</i>

76
00:04:30,931 --> 00:04:33,034
<i>Together, test pilots
and researchers</i>

77
00:04:33,137 --> 00:04:35,482
<i>need to figure out a safer way
to get airplanes</i>

78
00:04:35,586 --> 00:04:37,586
<i>into and out of
America's airports.</i>

79
00:04:39,551 --> 00:04:42,620
<i>What they've come up with
is a system called NextGen.</i>

80
00:04:45,172 --> 00:04:47,862
<i>NextGen will supply pilots
with the tools and information</i>

81
00:04:47,965 --> 00:04:49,655
<i>they need to make
many decisions</i>

82
00:04:49,758 --> 00:04:51,275
<i>that are now made
by controllers.</i>

83
00:04:53,241 --> 00:04:55,793
<i>At its heart is
a sophisticated piece
of equipment</i>

84
00:04:55,896 --> 00:04:59,068
<i>that will soon be added,
not to towers, but to planes.</i>

85
00:05:01,482 --> 00:05:02,551
<i>To see if it works,</i>

86
00:05:02,655 --> 00:05:04,758
<i>test pilots have to take it
for a ride.</i>

87
00:05:08,379 --> 00:05:12,241
We're liberating the airplane
to do what it's designed to do

88
00:05:12,344 --> 00:05:15,000
and not constraining it
by our management.

89
00:05:15,103 --> 00:05:18,172
Positive rate. Gear up.
CO-PILOT: Here it comes.

90
00:05:18,275 --> 00:05:21,724
<i>Researchers have installed a revolutionary
navigational computer</i>

91
00:05:21,827 --> 00:05:23,758
<i>in the back
of this executive jet.</i>

92
00:05:23,862 --> 00:05:26,034
We're currently flying
over Delaware.

93
00:05:26,137 --> 00:05:28,379
<i>It's called ADS-B.</i>

94
00:05:28,482 --> 00:05:32,413
<i>It stands for
Automatic Dependent
Surveillance Broadcast.</i>

95
00:05:32,517 --> 00:05:36,344
<i>It's a sophisticated GPS
receiver that paints
a detailed picture</i>

96
00:05:36,448 --> 00:05:39,448
<i>of any plane anywhere
near this flight.</i>

97
00:05:39,551 --> 00:05:43,655
So the pilot has what we call
situational awareness
of what's flying around him.

98
00:05:43,758 --> 00:05:45,172
Uh, the aircraft
then broadcasts

99
00:05:45,275 --> 00:05:47,241
that position
once a second,

100
00:05:47,344 --> 00:05:51,000
so any other aircraft
flying within RF range
of that aircraft

101
00:05:51,103 --> 00:05:53,758
now knows
its position as well.

102
00:05:53,862 --> 00:05:57,034
<i>There's nothing like this
in any cockpit today.</i>

103
00:05:57,137 --> 00:05:59,482
<i>Because it's still
experimental technology,</i>

104
00:05:59,586 --> 00:06:03,482
<i>the FAA is testing
this system in the cabin
of the aircraft.</i>

105
00:06:03,586 --> 00:06:06,655
<i>If tests like this succeed,
it will someday be
in the cockpit</i>

106
00:06:06,758 --> 00:06:08,517
<i>of every plane in America</i>

107
00:06:08,620 --> 00:06:10,482
<i>and eventually
around the world.</i>

108
00:06:12,689 --> 00:06:15,793
<i>Once the ADS-B system
is fully operational,</i>

109
00:06:15,896 --> 00:06:18,965
<i>everyone will know
where you are,
how high you're flying,</i>

110
00:06:19,827 --> 00:06:21,034
<i>and where you're headed.</i>

111
00:06:21,137 --> 00:06:25,862
It's a key piece of the future
because it is so accurate.

112
00:06:25,965 --> 00:06:29,206
<i>The computer that researchers
are putting to the test today</i>

113
00:06:29,310 --> 00:06:32,172
<i>is the central element
in the most significant
retooling</i>

114
00:06:32,275 --> 00:06:35,275
<i>of the American air traffic
control system
in half a century.</i>

115
00:06:36,862 --> 00:06:39,862
Human beings cannot be perfect
on a sustained basis,

116
00:06:39,965 --> 00:06:41,758
we can for certain periods
of time.

117
00:06:41,862 --> 00:06:44,000
<i>Therefore,
we have to expect failure.</i>

118
00:06:44,103 --> 00:06:46,241
<i>People make mistakes.</i>

119
00:06:46,344 --> 00:06:49,793
<i>It's a lesson
the airline industry
has learned the hard way.</i>

120
00:06:49,896 --> 00:06:51,724
<i>A lesson that
fundamentally shaped</i>

121
00:06:51,827 --> 00:06:54,068
<i>how planes travel
across the skies today.</i>

122
00:07:00,655 --> 00:07:02,724
<i>In the few years in which
they have been operating,</i>

123
00:07:02,827 --> 00:07:04,655
<i>the airlines have discovered
that their efforts</i>

124
00:07:04,758 --> 00:07:06,793
<i>to improve comforts
and services have...</i>

125
00:07:06,896 --> 00:07:08,379
<i>After the Second World War,</i>

126
00:07:08,482 --> 00:07:11,275
<i>Americans were traveling
by air in booming numbers.</i>

127
00:07:13,103 --> 00:07:16,758
<i>The earliest air traffic
controllers stood next
to runways.</i>

128
00:07:16,862 --> 00:07:18,965
<i>They waved flags
to guide planes in.</i>

129
00:07:20,862 --> 00:07:22,068
<i>As traffic increased,</i>

130
00:07:22,172 --> 00:07:24,068
<i>pilots also began
to use radios</i>

131
00:07:24,172 --> 00:07:25,896
<i>to stay in touch
with airports.</i>

132
00:07:27,793 --> 00:07:29,586
<i>The first air traffic
control towers</i>

133
00:07:29,689 --> 00:07:31,931
<i>were built as more and more
flights had to be handled.</i>

134
00:07:35,137 --> 00:07:37,931
<i>Airports have become
very busy places.</i>

135
00:07:38,034 --> 00:07:40,724
<i>And air traffic was beginning
to overwhelm controllers.</i>

136
00:07:47,137 --> 00:07:49,758
<i>June 30th, 1956.</i>

137
00:07:49,862 --> 00:07:52,655
<i>Los Angeles
International Airport.</i>

138
00:07:52,758 --> 00:07:56,172
<i>TWA Flight 2 lifts off
eastbound for Kansas City.</i>

139
00:08:06,344 --> 00:08:09,206
Airline flying in the '50s
was, uh, was really amazing.

140
00:08:09,310 --> 00:08:13,000
It was something
you dressed up for.

141
00:08:13,103 --> 00:08:17,206
Only people who could afford
a fairly high price
could actually fly.

142
00:08:17,310 --> 00:08:20,379
<i>The TWA
Flight is a Lockheed
Super Constellation...</i>

143
00:08:22,689 --> 00:08:26,241
<i>one of the most advanced
commercial airliners
of its time.</i>

144
00:08:26,344 --> 00:08:28,689
You won't find any pilot
who doesn't think
the Super Connie

145
00:08:28,793 --> 00:08:30,724
is one of the sexiest
airplanes ever designed.

146
00:08:36,517 --> 00:08:39,655
<i>Just minutes
behind TWA Flight 2,</i>

147

<i>United Airlines Flight 718</i>

148
00:08:42,137 --> 00:08:45,068
<i>takes off
from the same airport
on its way to Chicago.</i>

149
00:08:46,655 --> 00:08:50,586
<i>The system to track
both of the planes
is far from high tech.</i>

150
00:08:50,689 --> 00:08:53,931
The air traffic control center
consisted of a room

151
00:08:54,034 --> 00:08:55,862
with a map spread out
on a table

152
00:08:55,965 --> 00:08:58,586
<i>and the air
traffic controllers</i>

153
00:08:58,689 --> 00:09:02,586
<i>were moving markers
on that map to indicate</i>

154
00:09:02,689 --> 00:09:06,793
where each airplane was
and its last known position.

155
00:09:06,896 --> 00:09:09,896
<i>The pilots
radio their positions
to company dispatchers.</i>

156
00:09:10,965 --> 00:09:12,482
<i>Controllers use
this information</i>

157
00:09:12,586 --> 00:09:14,586
<i>to get a rough idea
of their flight paths.</i>

158
00:09:16,275 --> 00:09:19,482
<i>They were on radar
for a while in Los Angeles,</i>

159
00:09:19,586 --> 00:09:21,586
but once they got
outside that area,
there was no radar.

160
00:09:22,931 --> 00:09:25,000
<i>They were flying
under visual flight rules.</i>

161
00:09:25,103 --> 00:09:27,620
The rule is called
see and be seen.

162
00:09:28,620 --> 00:09:30,896
So, I see you,
you see me,

163
00:09:31,000 --> 00:09:33,827
we stay apart,
and we're responsible
for our own separation.

164
00:09:35,551 --> 00:09:38,379
<i>And except
for a few radars in
certain parts of the country,</i>

165
00:09:38,482 --> 00:09:40,206
<i>controllers didn't really know
where the airplanes were.</i>

166
00:09:40,310 --> 00:09:42,689
They were estimating
on their reports.

167
00:09:42,793 --> 00:09:45,931
<i>As the two planes get closer
to the Grand Canyon,</i>

168
00:09:46,034 --> 00:09:47,965
<i>the distance between them
disappears.</i>

169
00:09:49,689 --> 00:09:54,448
Both captains were used
to showing the Canyon off
on a clear day.

170
00:09:54,551 --> 00:09:57,586
<i>They could move the airplane
to the left, move it
to the right a little bit,</i>

171
00:09:57,689 --> 00:09:58,724
point out the Canyon
to people

172
00:09:58,827 --> 00:10:01,137
and get them to ooh and ah.

173
00:10:01,241 --> 00:10:05,000
<i>The United Flight
closes in on the TWA plane
from the right,</i>

174
00:10:05,103 --> 00:10:07,241
<i>unaware their paths
are about to cross.</i>

175
00:10:09,344 --> 00:10:12,068
People on one side
of the DC-7

176
00:10:12,172 --> 00:10:15,689
would have been able to see
the oncoming Constellation.

177
00:10:15,793 --> 00:10:17,862
Would have seen an airplane
against an azure sky,

178
00:10:17,965 --> 00:10:20,586
with fluffy clouds,
coming closer and closer.

179
00:10:21,758 --> 00:10:23,172
And they would have
felt the impact.

180
00:10:25,931 --> 00:10:27,655
<i>The Grand Canyon
is a graveyard</i>

181
00:10:27,758 --> 00:10:30,862
<i>for 128 passengers and crew
of two airliners</i>

182
00:10:30,965 --> 00:10:33,724
<i>which crashed on peaks
little more than a mile apart.</i>

183
00:10:33,827 --> 00:10:35,137
<i>None survived.</i>

184
00:10:35,241 --> 00:10:37,551
<i>It was the worst commercial
air disaster in history.</i>

185
00:10:40,206 --> 00:10:44,862
<i>The Grand Canyon crash
created huge banner headlines
across the nation</i>

186
00:10:44,965 --> 00:10:47,827
and a lot of pressure
on the government to
do something.

187
00:10:47,931 --> 00:10:49,034
We needed radar.

188
00:10:49,137 --> 00:10:50,862
We needed to buy it
and get it deployed

189
00:10:50,965 --> 00:10:52,655
<i>throughout the United
States immediately.</i>

190
00:10:52,758 --> 00:10:55,896
We had to change the system.
And we had to do it fast.

191
00:10:56,000 --> 00:10:59,551
<i>The crash
killed 128 people</i>

192
00:10:59,655 --> 00:11:02,413
<i>and changed the world of
air traffic control forever.</i>

193
00:11:07,275 --> 00:11:09,758
<i>Following a lengthy
investigation,</i>

194
00:11:09,862 --> 00:11:12,310
<i>the stark conclusion
was that the crash happened</i>

195
00:11:12,413 --> 00:11:15,965
<i>because the two planes
were outside of so-called
controlled airspace.</i>

196
00:11:19,758 --> 00:11:23,172
<i>TWA and United collided
over the Grand Canyon</i>

197
00:11:23,275 --> 00:11:25,620
primarily because neither
they nor the control system

198
00:11:25,724 --> 00:11:29,137
had the ability to know where
both of those airplanes
really were.

199
00:11:29,241 --> 00:11:31,172
<i>Once the planes left
the small area</i>

200
00:11:31,275 --> 00:11:33,482
<i>being monitored
by controllers,</i>

201
00:11:33,586 --> 00:11:37,241
<i>no one was paying attention
to where they were.</i>

202
00:11:37,344 --> 00:11:40,724
The "See and Avoid"
principle is a fraud,
and it always has been.

203
00:11:40,827 --> 00:11:44,103
The fact is
the faster you go,
it's a big sky,

204
00:11:44,206 --> 00:11:46,931
you've only got 180 degrees
of peripheral vision,

205
00:11:47,034 --> 00:11:49,206
<i>and you can't see
and avoid everything up there.</i>

206
00:11:52,068 --> 00:11:54,137
<i>In the wake
of the Grand Canyon accident,</i>

207
00:11:54,241 --> 00:11:58,793
<i>American airspace was
blanketed by radar.</i>

208
00:11:58,896 --> 00:12:03,655
<i>Planes were more stringently
confined to air corridors,
highways in the sky.</i>

209
00:12:06,137 --> 00:12:09,517
The air traffic control system
we have in the United States
today

210
00:12:09,620 --> 00:12:14,172
was designed with the Grand
Canyon accident in mind.

211
00:12:14,275 --> 00:12:17,931
<i>That crash
determined how far apart
airplanes should be spaced</i>

212
00:12:18,034 --> 00:12:21,310
<i>and where radar dishes
and air traffic control
centers should be built.</i>

213
00:12:23,482 --> 00:12:25,482
<i>It also resulted
in the formation</i>

214
00:12:25,586 --> 00:12:28,482
<i>of the Federal Aviation
Administration, The FAA.</i>

215
00:12:33,379 --> 00:12:36,137
<i>But now, 50 years later,</i>

216
00:12:36,241 --> 00:12:37,758
<i>the system needs
to change again.</i>

217
00:12:41,482 --> 00:12:45,413
<i>Today,
the system falls short of
the public's expectations,</i>

218
00:12:45,517 --> 00:12:46,965
being congested...

219
00:12:49,068 --> 00:12:49,965
slow...

220
00:12:51,620 --> 00:12:52,620
clunky...

221
00:12:53,758 --> 00:12:54,586
unpleasant.

222
00:12:58,862 --> 00:13:01,413
<i>As planes
fly faster and higher,</i>

223
00:13:01,517 --> 00:13:04,344
<i>it becomes harder
for controllers
to track their movements.</i>

224
00:13:06,344 --> 00:13:08,068
I think, in many respects,
we're in a, uh,

225
00:13:08,172 --> 00:13:11,413
a very similar situation
to where we were in the '50s.

226
00:13:11,517 --> 00:13:14,379
<i>The system has
to change massively.</i>

227
00:13:14,482 --> 00:13:17,241
<i>And the change
must happen soon</i>

228
00:13:17,344 --> 00:13:19,689
<i>before we are faced
with a major air accident</i>

229
00:13:19,793 --> 00:13:21,965
<i>that could take the lives
of hundreds of people.</i>

230
00:13:26,827 --> 00:13:29,275
<i>The technology onboard
the FAA flight</i>

231
00:13:29,379 --> 00:13:33,000
<i>might be the solution to
the overtaxed air traffic
control system.</i>

232
00:13:33,103 --> 00:13:35,310
<i>Test pilots regularly
take to the skies</i>

233
00:13:35,413 --> 00:13:36,758
<i>to help researchers prepare</i>

234
00:13:36,862 --> 00:13:39,551
<i>the new system
for America's airliners.</i>

235
00:13:39,655 --> 00:13:41,310
The beautiful thing
about ADS-B is,

236
00:13:41,413 --> 00:13:44,034
is it gives the pilots
in the cockpit

237
00:13:44,137 --> 00:13:46,793
and the air traffic
controllers basically
the same picture.

238
00:13:46,896 --> 00:13:50,344
<i>ADS-B is more
than a map of other planes.</i>

239
00:13:50,448 --> 00:13:54,448
<i>The idea is to show pilots
what now only air traffic
controllers can see...</i>

240
00:13:56,000 --> 00:13:58,620
<i>data about the planes that
are in a pilot's airspace.</i>

241
00:14:00,758 --> 00:14:03,931
With ADS-B, you'll see
who that other aircraft is.

242
00:14:04,034 --> 00:14:05,275
You'll see an identifier
on it.

243
00:14:07,862 --> 00:14:10,655
You'll be able to see planes
on runways.

244
00:14:10,758 --> 00:14:12,689
<i>You'll see planes
in the traffic pattern.</i>

245
00:14:12,793 --> 00:14:15,241
<i>And you'll get a better
feel for what's going on
around you.</i>

246
00:14:15,344 --> 00:14:17,586
Especially if you're at
an uncontrolled airport.

247
00:14:17,689 --> 00:14:20,724
We can also
see map information.

248
00:14:20,827 --> 00:14:22,827
We can see navigational aids.

249
00:14:22,931 --> 00:14:24,862
We can also see
other airports.

250
00:14:24,965 --> 00:14:27,655
<i>Giving pilots
all that information
in the cockpit</i>

251
00:14:27,758 --> 00:14:29,448
<i>will allow them
to make decisions</i>

252
00:14:29,551 --> 00:14:32,827
<i>about how to get to
their destinations quickly
and safely.</i>

253
00:14:35,068 --> 00:14:38,310
<i>The current system
relies on radars</i>

254
00:14:38,413 --> 00:14:41,000
<i>for the detection
and tracking of aircraft.</i>

255
00:14:41,103 --> 00:14:44,206
<i>And radar was
a great technology
in 1940,</i>

256
00:14:44,310 --> 00:14:47,206
<i>but fundamentally,
it's very sloppy.</i>

257
00:14:47,310 --> 00:14:50,206
<i>Today, ground-based radar
bounces radio signals</i>

258
00:14:50,310 --> 00:14:52,862
<i>off an airplane
to calculate its position.</i>

259
00:14:52,965 --> 00:14:55,758
<i>It can be off
by as much as two miles.</i>

260
00:14:55,862 --> 00:14:59,724
That's why we keep aircraft
three miles or more apart,

261
00:14:59,827 --> 00:15:02,620
<i>because we're just not
that confident
of the solution.</i>

262
00:15:03,482 --> 00:15:05,137
<i>With NextGen,</i>

263
00:15:05,241 --> 00:15:09,241
<i>an onboard GPS unit will
constantly receive signals
from a GPS satellite.</i>

264
00:15:11,000 --> 00:15:13,034
<i>This will tell pilots
where they are</i>

265
00:15:13,137 --> 00:15:15,379
<i>down to within
a few hundred feet.</i>

266
00:15:18,482 --> 00:15:20,793
<i>With a more
accurate picture of airspace,</i>

267
00:15:20,896 --> 00:15:23,103
<i>airliners will be able
to fly closer together.</i>

268
00:15:25,172 --> 00:15:28,758
<i>The FAA hopes this will
help relieve the congestion
at busy airports.</i>

269
00:15:31,413 --> 00:15:36,103
<i>Today, only controllers
have an accurate picture
of air traffic.</i>

270
00:15:36,206 --> 00:15:39,517
<i>They use this information
to guide pilots around
potential problems.</i>

271
00:15:41,896 --> 00:15:45,275
<i>The pilots themselves
have no way
to independently confirm</i>

272
00:15:45,379 --> 00:15:48,310
<i>where they are in relation
to all other flights.</i>

273
00:15:48,413 --> 00:15:50,310
<i>They must rely
on controllers to tell them.</i>

274
00:15:51,517 --> 00:15:53,517
<i>The weakness of
the system was exposed</i>

275
00:15:53,620 --> 00:15:56,172
<i>years before
NextGen tests began.</i>

276
00:16:03,241 --> 00:16:05,862
<i>Labor Day weekend, 1986.</i>

277
00:16:05,965 --> 00:16:09,310
Aeromexico 498,
traffic ten o'clock.
One mile...

278
00:16:09,413 --> 00:16:11,103
<i>Approach Controller
Walter White</i>

279

<i>guides Aeromexico Flight 498
in for a landing</i>

280
00:16:14,482 --> 00:16:16,068
<i>at Los Angeles
International Airport.</i>

281
00:16:19,517 --> 00:16:22,482
<i>The airspace around LAX
is very tightly controlled.</i>

282
00:16:24,551 --> 00:16:27,827
<i>It's called the TCA,
the Terminal Control Area.</i>

283
00:16:31,103 --> 00:16:35,000
<i>As Aeromexico Flight 498
closes in on the airport,</i>

284
00:16:35,103 --> 00:16:38,413
<i>Walter White sees a plane
he does not expect
on his radar.</i>

285
00:16:38,517 --> 00:16:41,551
<i>Uh, one approach
on a flight from Fullerton.</i>

286
00:16:41,655 --> 00:16:43,793
Cruising altitude is 4,500.

287
00:16:43,896 --> 00:16:46,586
<i>- We'd like following.</i>
- Okay. You're are right
in the middle of the TCA, sir.

288
00:16:46,689 --> 00:16:48,172
<i>Grumman six-six-Romeo,</i>

289

<i>I suggest in future,
you look at your TCA chart.</i>

290
00:16:52,068 --> 00:16:54,482
There was an aircraft
that was east of the airport

291
00:16:54,586 --> 00:16:56,758
which he became involved in.

292
00:16:56,862 --> 00:16:59,206
<i>That was what
they called a violator.</i>

293
00:16:59,310 --> 00:17:00,931
<i>In many cases,</i>

<i>out of
the controlled airspace.</i>

298
00:17:12,448 --> 00:17:13,965
<i>You just had an aircraft pass</i>

299
00:17:14,068 --> 00:17:16,310
right off your left
above you at 5,000

300
00:17:16,413 --> 00:17:20,137
and we run a lot of jets
right through there at 3,500.

301
00:17:20,241 --> 00:17:22,793
<i>But White
doesn't realize that
there's another plane</i>

302
00:17:22,896 --> 00:17:25,206
<i>dangerously off course.</i>

303
00:17:25,310 --> 00:17:27,724
We should be able to see
the ocean by now.

304
00:17:27,827 --> 00:17:29,758
Take a look at the map

311
00:17:52,448 --> 00:17:55,000
This can't be!

312
00:17:55,103 --> 00:17:57,379
<i>The jet plunges
towards Cerritos,</i>

313
00:17:57,482 --> 00:17:59,655
<i>a suburban community

314
00:18:06,000 --> 00:18:08,379
Aeromexico 498.
Los Angeles Approach.

315
00:18:10,620 --> 00:18:13,000
I'm sitting there
talking with the two
departure controllers,

316
00:18:13,103 --> 00:18:14,862
and not really thinking.

317
00:18:14,965 --> 00:18:17,103
<i>I hear Walter say
something like...</i>

318
00:18:17,206 --> 00:18:18,068
I think I lost one.

319
00:18:20,172 --> 00:18:22,482
Aeromexico 498,
Los Angeles approach.

320
00:18:22,586 --> 00:18:24,689
<i>That immediately
got everybody's attention.</i>

321
00:18:24,793 --> 00:18:26,034
<i>So I looked at the radars,</i>

322
00:18:26,137 --> 00:18:28,862
<i>and could hear him
calling Aeromexico 498.</i>

323
00:18:28,965 --> 00:18:30,620
...498, Los Angeles approach.

324
00:18:34,413 --> 00:18:37,724
<i>The crash devastates
the community of Cerritos.</i>

325
00:18:37,827 --> 00:18:41,000
<i>Fifteen people on the ground
are killed in the disaster,</i>

326
00:18:41,103 --> 00:18:44,413
<i>along with all 64 people
on the Aeromexico jet.</i>

327
00:18:47,758 --> 00:18:51,413
<i>The Piper Cherokee is found
in a nearby schoolyard.</i>

328
00:18:51,517 --> 00:18:53,758
<i>All three people
on the small plane
have been killed.</i>

329
00:18:55,275 --> 00:18:57,000
<i>The fact
of the matter is</i>

330
00:18:57,103 --> 00:18:59,310
<i>that the Cherokee
flew into the TCA</i>

331
00:18:59,413 --> 00:19:03,103
and hit the DC9
in restricted airspace
without a clearance.

332
00:19:03,206 --> 00:19:06,482
<i>The National
Transportation Safety Board
questions Walter White</i>

333
00:19:06,586 --> 00:19:09,620
<i>about what he saw
on his radar display.</i>

334
00:19:09,724 --> 00:19:14,344
At any time, did you see
the Piper Cherokee
on your scope?

335
00:19:15,068 --> 00:19:15,896
No.

336
00:19:16,793 --> 00:19:18,241
No, sir.

337
00:19:18,344 --> 00:19:20,758
The Piper's target was
not displayed.

338
00:19:20,862 --> 00:19:24,206
It is my belief
that it was not
on my radar scope.

339
00:19:24,310 --> 00:19:27,793
He, uh, was positive

340
00:19:27,896 --> 00:19:29,965
that the aircraft
was not there for him to see.

341
00:19:31,586 --> 00:19:33,310
<i>But when
investigators finally get</i>

342
00:19:33,413 --> 00:19:35,931
<i>the air traffic
control radar records,</i>

343
00:19:36,034 --> 00:19:38,137
<i>they conclude the Piper
should have been visible.</i>

344
00:19:41,137 --> 00:19:42,655
<i>We were
able to determine</i>

345
00:19:42,758 --> 00:19:44,862
<i>that the aircraft
that collided</i>

346
00:19:44,965 --> 00:19:47,758
with Aeromexico
was there to be seen.

347
00:19:49,137 --> 00:19:50,620
<i>Controllers had been complaining</i>

348
00:19:50,724 --> 00:19:52,034
<i>about the radars
for a long time.</i>

349
00:19:53,620 --> 00:19:55,827
We had reported problems
with the radar

350
00:19:55,931 --> 00:19:59,413
not picking up targets
several times.

351
00:19:59,517 --> 00:20:03,482
You may lose one target,
you may lose two targets.

352
00:20:03,586 --> 00:20:07,896
It may not be presented
for one sweep.

353
00:20:09,000 --> 00:20:11,137
Did you see
the Piper Cherokee

354
00:20:11,241 --> 00:20:13,206
- on your scope?
- No, sir.

355
00:20:13,310 --> 00:20:15,724
But that doesn't mean
that the target isn't there.

356
00:20:15,827 --> 00:20:20,068
A blind spot is only
an instantaneous thing.

357
00:20:20,172 --> 00:20:22,689
It's not a continuous thing.

358
00:20:22,793 --> 00:20:25,034
<i>He was looking
at one and trying
to keep it clear.</i>

359
00:20:26,965 --> 00:20:29,724
<i>Lost track of another one
that just happened to be at
the same altitude</i>

360
00:20:29,827 --> 00:20:31,689
as the approaching
Aeromexico jet.

361
00:20:37,413 --> 00:20:39,137
<i>It was a one
in a billion chance,</i>

362
00:20:39,241 --> 00:20:41,482
but that one in a billion
came up that particular day.

363
00:20:46,689 --> 00:20:48,034
<i>The collision
over Los Angeles</i>

364
00:20:48,137 --> 00:20:49,620
<i>drew attention to weaknesses</i>

365
00:20:49,724 --> 00:20:53,482
<i>in the radar systems used
by air traffic controllers</i>

366
00:20:53,586 --> 00:20:55,551
<i>and led to some
much-needed improvements.</i>

367
00:20:56,827 --> 00:20:59,482
Mode C Intruder
is an automated program

368
00:20:59,586 --> 00:21:00,862
that is now incorporated

369
00:21:00,965 --> 00:21:03,655
in all our major
radar facilities.

370
00:21:03,758 --> 00:21:07,758
That, if an aircraft
should inadvertently intrude,

371
00:21:07,862 --> 00:21:10,241
the controller
will now be given

372
00:21:10,344 --> 00:21:12,862
a visual and an aural alert,

373
00:21:12,965 --> 00:21:15,310
thus giving him
time to provide

374
00:21:15,413 --> 00:21:18,448
<i>a timely warning
to the pilot.</i>

375
00:21:18,551 --> 00:21:20,655
<i>After the collision
over Los Angeles,</i>

376
00:21:20,758 --> 00:21:23,172
<i>radar systems at the airport
were upgraded.</i>

377
00:21:27,379 --> 00:21:30,758
<i>The next generation
of air traffic management
will only use radar</i>

378
00:21:30,862 --> 00:21:32,862
<i>if the GPS system fails.</i>

379
00:21:34,758 --> 00:21:38,034
<i>NextGen is also targeting
another weakness in
the current system,</i>

380
00:21:38,758 --> 00:21:39,620
<i>the radio.</i>

381
00:21:41,482 --> 00:21:45,206
<i>Today, pilots and controllers
use radios to talk
to one another.</i>

382
00:21:45,310 --> 00:21:47,827
We're now descending
to one-niner-zero...

383
00:21:47,931 --> 00:21:51,000
<i>The system
depends on clear,
precise language.</i>

384
00:21:51,103 --> 00:21:52,965
<i>Misunderstandings are common.</i>

385
00:21:53,068 --> 00:21:56,172
<i>And they've caused some of
the most tragic air disasters
in history.</i>

386
00:21:59,068 --> 00:22:03,206
<i>As the FAA test flight
flies high west
of Atlantic City,</i>

387
00:22:03,310 --> 00:22:07,103
<i>its radio keeps the pilots
in touch with controllers.</i>

388
00:22:07,206 --> 00:22:09,241
<i>Vector for sequence
for the downwind runway 22.</i>

389
00:22:10,241 --> 00:22:12,724
Okay,
1-0-0, clear for the ILS.

390
00:22:12,827 --> 00:22:15,379
<i>But in the air traffic
system of the future,</i>

391
00:22:15,482 --> 00:22:19,034
<i>pilots and controllers
will communicate
less frequently.</i>

392
00:22:19,137 --> 00:22:21,620
The controller and the pilot
can now work together

393
00:22:21,724 --> 00:22:24,034
to resolve issues
instead of wasting
a lot of time

394
00:22:24,137 --> 00:22:26,103
explaining what
the issues are.

395
00:22:26,206 --> 00:22:29,862
<i>Mistakes can be made
for a number of reasons.</i>

396
00:22:29,965 --> 00:22:33,724
<i>English is the international
language of aviation.</i>

397
00:22:33,827 --> 00:22:38,241
<i>But pronunciation, accent
and emotion alter the way
any language is spoken.</i>

398
00:22:40,137 --> 00:22:41,758
<i>Nowhere is this
better understood</i>

399
00:22:41,862 --> 00:22:43,655
<i>than in the air traffic
control tower</i>

400
00:22:43,758 --> 00:22:46,034
<i>at John F. Kennedy
International Airport.</i>

401
00:22:47,931 --> 00:22:50,103
If you listen
on any control frequency,

402
00:22:50,206 --> 00:22:52,137
you're going to hear
a lot of people say,
"Would you say that again?",

403
00:22:52,241 --> 00:22:53,310
"Say again, over, please."

404
00:22:54,344 --> 00:22:55,931
<i>The airspace above JFK</i>

405
00:22:56,034 --> 00:22:58,000
<i>is frequented by one
of the most international</i>

406
00:22:58,103 --> 00:23:00,344
<i>collections of pilots
in the world.</i>

407

<i>Maintaining clear radio
communications</i>

408

<i>can prove challenging
to controllers here.</i>

409
00:23:08,206 --> 00:23:10,551
There's pressure,
because that's the business
they're in.

410
00:23:10,655 --> 00:23:13,310
The business
is moving passengers
from A to B.

411
00:23:13,413 --> 00:23:14,586
That's what
the airlines are paid,

412

<i>and the controllers are
paid to help that work.</i>

413

<i>When pressure mounts,</i>

414
00:23:19,310 --> 00:23:22,137

<i>Bad weather

<i>There was

There were a couple
other systems converging.

428

And a lot of times,
they'll converge
in the New York Area there

429
00:24:13,931 --> 00:24:15,517

They were progressively

This certainly would put
some stress on the crew,

uh, as to fact
they want to go
from A to B.

440

448
00:25:07,344 --> 00:25:10,068
<i>They've used up
almost all of their fuel
while waiting their turn.</i>

449
00:25:10,172 --> 00:25:11,275
...set him up
for his alternate.

450
00:25:11,379 --> 00:25:13,482
- What is his speed now?
- I'm not sure, to be honest.

451
00:25:13,586 --> 00:25:16,482
Slow him to 180 knots
and I'll take him.

452

Good day.

462
00:25:38,793 --> 00:25:41,206
It was extremely important
that Avianca 52

463
00:25:41,310 --> 00:25:43,482
landed on their first
approach to JFK.

464
00:25:43,586 --> 00:25:46,241
The voice recorder revealed
that the Captain was certainly

465
00:25:46,344 --> 00:25:48,000
quite concerned
about the fuel state.

466
00:25:51,103 --> 00:25:54,965
<i>At JFK,
only one runway is being
used for landings.</i>

Are we clear to land? No?

476
00:26:15,655 --> 00:26:16,862
Yes, sir.
We are clear to land.

479

480
00:26:24,275 --> 00:26:25,241

481
00:26:26,517 --> 00:26:28,758
I'm sure In their minds
they thought,

482
00:26:28,862 --> 00:26:31,620
well, they even commented
on a cockpit voice recorder.

483
00:26:31,724 --> 00:26:33,689
"We're being handled," or,
"We're being taken care of."

484

<i>Four kilometers

<i>the flight hits
ferocious winds.</i>

487
00:26:45,241 --> 00:26:48,206
They were getting, like,
60 knots of wind on the nose,

488
00:26:48,310 --> 00:26:49,586
and then, as they
descended on down

489
00:26:49,689 --> 00:26:52,310
through about 500 feet
to the ground,

490
00:26:52,413 --> 00:26:53,586
they were down to 20 knots.

491
00:26:55,344 --> 00:26:59,379
So that's a 40-knot change
in 1,000 feet of elevation.

492
00:26:59,482 --> 00:27:01,931
<i>That's a lot.</i>

493
00:27:02,034 --> 00:27:03,827
- This is the wind shear.
- <i>A dramatic change</i>

494

495
00:27:09,241 --> 00:27:11,068
- Glideslope!
- <i>Glideslope.</i>

496
00:27:11,172 --> 00:27:13,896
<i>Glideslope. Glideslope.</i>

497

<i>The runway. Where is it?</i>

498
00:27:16,000 --> 00:27:17,758
- I don't see it.
<i>Pull up. Pull up.</i>

499
00:27:17,862 --> 00:27:20,827
<i>The plane
is thrown towards the ground
by the winds.</i>

500
00:27:20,931 --> 00:27:22,344
<i>Pull up. Pull up.</i>

501
00:27:25,620 --> 00:27:28,034
<i>The airplane
was about 200 feet
above the ground,</i>

502
00:27:28,137 --> 00:27:30,172
about two miles
from the runway,

503
00:27:30,275 --> 00:27:32,896
which was well below
the glideslope
and very dangerous.

504
00:27:33,000 --> 00:27:36,620
So, the airplane almost
crashed on its first approach.

505
00:27:36,724 --> 00:27:38,103
Give me

<i>Controllers in New York

These guys were out

"We were out."

519

523
00:28:27,896 --> 00:28:30,137

00:33:03,758 --> 00:33:06,517
<i>at 45 seconds before
the potential collision.</i>

594
00:33:06,620 --> 00:33:08,689
And then, at approximately
25 seconds or so

595
00:33:08,793 --> 00:33:09,931
before
the potential collision,

596
00:33:10,034 --> 00:33:11,482
a resolution advisory
is given

597
00:33:11,586 --> 00:33:13,482
<i>to actually tell the pilots</i>

598
00:33:13,586 --> 00:33:16,448
<i>to climb or descend
to avoid the altitude
of the other aircraft.</i>

599
00:33:19,344 --> 00:33:21,103
Normally, air traffic
will call that to us.

600
00:33:21,206 --> 00:33:22,724
- Yeah.
- But they didn't even
call the traffic.

601
00:33:22,827 --> 00:33:24,586
- No.
- So that TCAS helped a lot.

602
00:33:24,689 --> 00:33:28,000
<i>TCAS can help pilots
of approaching planes
avoid collisions.</i>

603
00:33:28,931 --> 00:33:30,172
<i>But with the new system,</i>

604
00:33:30,275 --> 00:33:32,379
<i>pilots will be able
to prevent their planes</i>

605
00:33:32,482 --> 00:33:35,586
<i>from getting dangerously close
in the first place.</i>

606
00:33:35,689 --> 00:33:39,517
You know, with ADS-B,
we're going to be able to see
that traffic on the display.

607
00:33:39,620 --> 00:33:43,034
So the avionics can have
smarts built into it to

608
00:33:43,137 --> 00:33:46,103
warn the pilot
when he's approaching
another aircraft.

609
00:33:46,206 --> 00:33:48,000
<i>Today,
the system works perfectly.</i>

610
00:33:49,482 --> 00:33:52,551
<i>The pilots of the test flight
see the danger and avoid it.</i>

611
00:33:53,896 --> 00:33:56,724
<i>TCAS can help pilots
avoid a collision,</i>

612
00:33:56,827 --> 00:33:59,241
<i>but having it onboard
is no guarantee</i>

613
00:33:59,344 --> 00:34:00,586
<i>that an accident
won't happen.</i>

706
00:39:14,827 --> 00:39:16,793
- Why didn't you?
- We weren't told to.

707
00:39:16,896 --> 00:39:19,103

from the ground,</i>

741
00:41:11,724 --> 00:41:13,137
which is where we expect it
to happen,

742
00:41:13,241 --> 00:41:16,482
to save these two airplanes
from being head on
at the same altitude.

743
00:41:16,586 --> 00:41:17,379
...zero X-ray Lima.

744
00:41:33,068 --> 00:41:36,137
<i>Back over Atlantic City,
pilots are preparing to bring</i>

745
00:41:36,241 --> 00:41:37,827
<i>their test flight in
for a landing.</i>

746
00:41:39,448 --> 00:41:42,655
<i>Today, the flight has
to stay within tightly
confined boundaries</i>

747
00:41:42,758 --> 00:41:46,000
<i>set out
by air traffic controllers.</i>

748
00:41:46,103 --> 00:41:50,413
<i>But when all aircraft
are equipped with ADS-B,
that won't be the case.</i>

749
00:41:52,137 --> 00:41:54,000
<i>If the aircraft could fly</i>

750
00:41:54,103 --> 00:41:57,310
on a path that was
optimum for them,

751
00:41:57,413 --> 00:42:00,000
and optimum
for the traffic system,

752
00:42:00,103 --> 00:42:02,689
<i>we could use a lot more
of the airspace</i>

753
00:42:03,724 --> 00:42:04,689
<i>than we do today.</i>

754
00:42:04,793 --> 00:42:06,137
We're going to have airplanes

755
00:42:06,241 --> 00:42:08,068
flying directly where
they need to fly,

756
00:42:08,172 --> 00:42:10,758
and computers
keeping them apart.

757
00:42:10,862 --> 00:42:14,034
<i>At the FAA,
researchers have been
designing systems</i>

758
00:42:14,137 --> 00:42:17,862
<i>that get flights from A to B
in a whole new way.</i>

759
00:42:17,965 --> 00:42:20,137
<i>Right now, there's no way
for controllers to know</i>

760
00:42:20,241 --> 00:42:21,586
<i>the exact location
of a plane.</i>

761
00:42:23,103 --> 00:42:25,724
<i>That's why flights are
confined to pre-set highways</i>

762
00:42:25,827 --> 00:42:26,931
<i>to keep them
from colliding.</i>

763
00:42:28,620 --> 00:42:30,862
<i>With GPS-based NextGen,</i>

764
00:42:30,965 --> 00:42:33,655
<i>a pilot can follow any route
he chooses,</i>

765
00:42:33,758 --> 00:42:37,379
<i>provided there aren't
any other planes in his path.</i>

766
00:42:37,482 --> 00:42:40,275
<i>He can choose
a much more direct route
to his destination.</i>

767
00:42:42,034 --> 00:42:44,103
If we could have airplanes
going in all directions

768
00:42:44,206 --> 00:42:46,862
and more efficiently directly
to where they want to go,

769
00:42:46,965 --> 00:42:50,172
we would be able to double,
triple, maybe even quadruple

770
00:42:50,275 --> 00:42:52,620
the number of aircraft
that we could safely handle

771
00:42:52,724 --> 00:42:53,931
in the skies at one time.

772
00:42:55,172 --> 00:42:57,896
<i>By charting
their own route,</i>

773
00:42:58,000 --> 00:43:02,103
<i>ADS-B will allow pilots
to keep a safe distance
from other planes</i>

774
00:43:02,206 --> 00:43:05,586
<i>without having to stick to
a pre-set highway in the sky.</i>

775
00:43:05,689 --> 00:43:07,965
<i>Maintaining that distance
is important,</i>

776
00:43:08,068 --> 00:43:09,448
<i>because even
the best technology</i>

777
00:43:09,551 --> 00:43:11,000
<i>can't keep airplanes apart.</i>

778

00:43:52,379 --> 00:43:54,275
<i>that both flights

790

<i>Present heading is...</i>

00:44:06,793 --> 00:44:08,206
<i>It was a standard practice</i>

796
00:44:08,310 --> 00:44:10,793
at the ATC company
that at night,

797

00:44:46,103 --> 00:44:47,103
Six hundred.

<i>When the air traffic

He's guiding us down.

825
00:45:28,931 --> 00:45:32,172
We're not accustomed
to not trusting controllers.

826
00:45:34,724 --> 00:45:35,724
In civil aviation,

827
00:45:35,827 --> 00:45:38,241
there were lots of situations
when pilots didn't follow

828
00:45:38,344 --> 00:45:40,310
instructions of
the controller,

829
00:45:40,413 --> 00:45:43,000
and that led to plane crashes
or other accidents.

830
00:45:45,448 --> 00:45:46,758
Expedite descent level

831

<i>with just seconds
to decide,</i>

833
00:45:50,413 --> 00:45:53,827
<i>the Russian pilots follow
the controller's direction.</i>

834
00:45:53,931 --> 00:45:56,862
<i>At the same time,
the DHL jet
is also descending.</i>

835
00:45:58,000 --> 00:45:59,275
<i>Increase descent.</i>

844
00:46:35,137 --> 00:46:37,172
Bravo Tango Charlie
two-nine-three-seven.

845
00:46:38,448 --> 00:46:40,344
Bravo Tango Charlie.

846
00:46:45,896 --> 00:46:48,586
<i>Both flights crash
near Lake Constance
in Germany.</i>

847
00:46:49,413 --> 00:46:51,655
<i>Seventy-one people are killed.</i>

848
00:46:51,758 --> 00:46:52,896
<i>There are no survivors.</i>

849
00:46:55,344 --> 00:46:58,448
<i>The collision leaves
air traffic experts
at a critical crossroads.</i>

850
00:47:02,241 --> 00:47:07,344
If I have to
summarize the advice
that we gave the world,

851
00:47:07,448 --> 00:47:10,103
<i>if a warning
comes from ACAS,</i>

852
00:47:10,206 --> 00:47:14,344
<i>pilots should immediately
follow it at all times.</i>

853
00:47:14,448 --> 00:47:17,758
<i>If the Russian
pilots had followed
the computer's instructions,</i>

854
00:47:17,862 --> 00:47:19,413
<i>the accident would not
have happened.</i>

855
00:47:21,275 --> 00:47:25,827
With the benefit of hindsight,
you always ask yourself,
"Could we have done more?"

856
00:47:25,931 --> 00:47:29,758
And an accident
is a wakeup call
for everybody.

857
00:47:29,862 --> 00:47:31,931
<i>The disaster highlighted
the potential value</i>

858
00:47:32,034 --> 00:47:33,758
<i>of automated systems.</i>

859
00:47:33,862 --> 00:47:36,586
<i>And proved again
how fatal human errors can be.</i>

860
00:47:40,724 --> 00:47:43,172
<i>It's an important lesson
for the developers of NextGen.</i>

861
00:47:45,103 --> 00:47:47,724
<i>Technology can provide
humans with information,</i>

862
00:47:47,827 --> 00:47:49,275
<i>but can't control
what they do with it.</i>

863
00:47:50,896 --> 00:47:52,344
...before landing?

864
00:47:52,448 --> 00:47:56,206
<i>Over Atlantic City,
the FAA jet is
on its final approach.</i>

865
00:47:56,310 --> 00:47:58,793
<i>Runway is clear.
Bring the flaps to 16...</i>

866
00:47:58,896 --> 00:48:00,482
<i>Its two-hour test flight
has brought</i>

867
00:48:00,586 --> 00:48:02,275
<i>NextGen one-step closer</i>

868
00:48:02,379 --> 00:48:04,000
<i>to being installed
on commercial airplanes.</i>

869
00:48:11,241 --> 00:48:12,275
Nice job, guys.

00:48:12,379 --> 00:48:13,931
CO-PILOT: Two reverses.

Speeds at 90.
I got the yoke.

872
00:48:18,448 --> 00:48:20,103
<i>When ADS-B
is everywhere</i>

873
00:48:20,206 --> 00:48:21,965
<i>and the data is being
displayed in the cockpit,</i>

874
00:48:23,000 --> 00:48:24,862
that will allow
the airlines to fly

875
00:48:24,965 --> 00:48:26,655
hugely more efficiently.

876
00:48:29,827 --> 00:48:31,413
<i>Over the past 50 years,</i>

877
00:48:31,517 --> 00:48:33,862
<i>air traffic control
has evolved tremendously.</i>

878
00:48:38,655 --> 00:48:39,517
<i>Human error...</i>

879
00:48:42,793 --> 00:48:44,034
<i>technical difficulties...</i>

880
00:48:46,206 --> 00:48:47,379
<i>and poor communication...</i>

881
00:48:49,448 --> 00:48:52,482
<i>have taken the lives
of hundreds of people</i>

882
00:48:52,586 --> 00:48:55,103
<i>and uncovered
deadly weaknesses
in the current system.</i>

883
00:48:59,103 --> 00:49:02,965
<i>Today, those weaknesses
are one step closer
to being fixed.</i>

884
00:49:03,068 --> 00:49:05,551
<i>I think
the NextGen system,
as it has evolved now,</i>

885
00:49:05,655 --> 00:49:06,827
<i>is really going
to be excellent.</i>

886
00:49:06,931 --> 00:49:09,379
It's going to start
in the direction
that we need to go

887
00:49:10,068 --> 00:49:11,931
<i>for the future.</i>

888
00:49:12,034 --> 00:49:13,931
<i>The elements
that make up NextGen</i>

889
00:49:14,034 --> 00:49:16,068
<i>will be introduced slowly
over the next decade.</i>

890
00:49:17,413 --> 00:49:19,758
<i>Piece by piece,
the whole new system</i>

891
00:49:19,862 --> 00:49:23,068
