WEBVTT

1
00:00:00.040 --> 00:00:03.200
<v Speaker 1>I want you to picture the dead of winter. It's

2
00:00:03.200 --> 00:00:04.679
<v Speaker 1>February twelve, two thousand and.

3
00:00:04.719 --> 00:00:06.360
<v Speaker 2>Nine, right in the heart of winter.

4
00:00:06.480 --> 00:00:09.599
<v Speaker 1>Yeah, just outside of Buffalo, New York. It's night. It

5
00:00:09.679 --> 00:00:14.400
<v Speaker 1>is brutally cold, and there's this heavy, just disorienting mix

6
00:00:14.519 --> 00:00:16.600
<v Speaker 1>of snow and fog hanging in the air.

7
00:00:16.640 --> 00:00:18.399
<v Speaker 2>And if you put yourself in the shows of a

8
00:00:18.399 --> 00:00:20.839
<v Speaker 2>first responder that night, you know, you're sitting in your

9
00:00:20.920 --> 00:00:23.320
<v Speaker 2>vehicle when a dispatch call comes over the radio, that

10
00:00:23.440 --> 00:00:27.280
<v Speaker 2>just it literally stops your heart. I can't even imagine

11
00:00:27.399 --> 00:00:31.000
<v Speaker 2>plane crash, house on fire. You hit the sirens, and

12
00:00:31.039 --> 00:00:34.640
<v Speaker 2>you just rush toward six h thirty eight Long Street.

13
00:00:34.759 --> 00:00:38.399
<v Speaker 2>It's in a quiet suburban neighborhood called Clarence Center, right, and.

14
00:00:38.359 --> 00:00:41.399
<v Speaker 1>As you turn the final corner, the entire village is

15
00:00:41.439 --> 00:00:44.240
<v Speaker 1>suddenly illuminated. I mean, there are these towering flames reaching

16
00:00:44.240 --> 00:00:47.439
<v Speaker 1>into the sky. The heat radiating off the crash site

17
00:00:47.479 --> 00:00:49.079
<v Speaker 1>is so intense it feels like you're standing next to

18
00:00:49.119 --> 00:00:50.560
<v Speaker 1>a massive bonfire.

19
00:00:50.079 --> 00:00:52.479
<v Speaker 2>Even though you're forced to stay like one hundred.

20
00:00:52.159 --> 00:00:55.479
<v Speaker 1>Feet back exactly, and peering through the thick black smoke,

21
00:00:56.399 --> 00:01:00.359
<v Speaker 1>you see this surreal, honestly almost impossible sight. A two

22
00:01:00.399 --> 00:01:04.200
<v Speaker 1>story suburban house has been completely criffed into its own basement,

23
00:01:04.519 --> 00:01:07.599
<v Speaker 1>and sitting directly on top of the burning debris is

24
00:01:07.680 --> 00:01:11.319
<v Speaker 1>the massive severed tail section of a commercial airplane.

25
00:01:11.359 --> 00:01:14.359
<v Speaker 2>Fifty people lost their lives in that wreckage, all forty

26
00:01:14.439 --> 00:01:17.439
<v Speaker 2>nine passengers and crew on board Continental Connection flight three

27
00:01:17.480 --> 00:01:21.519
<v Speaker 2>four oh seven, plus one man on the ground, Douglas Wallinski,

28
00:01:21.799 --> 00:01:24.680
<v Speaker 2>who was actually inside the house at the time.

29
00:01:24.560 --> 00:01:27.640
<v Speaker 1>Right His wife and daughter managed to escape the flames, thankfully,

30
00:01:27.719 --> 00:01:31.040
<v Speaker 1>but for everyone else, the destruction was just absolute. It was.

31
00:01:31.400 --> 00:01:33.959
<v Speaker 1>So we've gathered a massive stack of sources today to

32
00:01:34.000 --> 00:01:36.359
<v Speaker 1>try and make sense of this tragedy. For this deep dive,

33
00:01:36.840 --> 00:01:40.920
<v Speaker 1>we're pulling directly from the official NTSB accident reports, which

34
00:01:40.959 --> 00:01:44.680
<v Speaker 1>are thousands of pages long, along with investigative journalism on

35
00:01:44.719 --> 00:01:48.359
<v Speaker 1>regional airlines and some really cutting edge research on aerospace

36
00:01:48.560 --> 00:01:49.840
<v Speaker 1>human factors engineering.

37
00:01:49.959 --> 00:01:52.760
<v Speaker 2>Because our mission here is to step into the shoes

38
00:01:52.799 --> 00:01:54.560
<v Speaker 2>of the investigators exactly.

39
00:01:54.599 --> 00:01:56.599
<v Speaker 1>We aren't just looking for a broken part or some

40
00:01:56.680 --> 00:02:00.200
<v Speaker 1>mechanical failure. We're going to uncover the hidden psychological and

41
00:02:00.239 --> 00:02:04.040
<v Speaker 1>systemic elements that caused highly trained professionals to make just

42
00:02:04.079 --> 00:02:07.799
<v Speaker 1>an unthinkable error. And you know how the ashes of

43
00:02:07.799 --> 00:02:10.240
<v Speaker 1>flight three four oh seven fundamentally change the laws of

44
00:02:10.240 --> 00:02:10.599
<v Speaker 1>the sky.

45
00:02:11.000 --> 00:02:14.039
<v Speaker 2>The sheer complexity of this investigation makes it a defining

46
00:02:14.080 --> 00:02:18.000
<v Speaker 2>moment in aviation history. Really, because the evidence trails lead

47
00:02:18.120 --> 00:02:20.879
<v Speaker 2>far away from the crash slight itself. It proves that

48
00:02:20.960 --> 00:02:25.199
<v Speaker 2>a disaster of this magnitude is rarely a single catastrophic event.

49
00:02:25.360 --> 00:02:26.879
<v Speaker 1>It's a chain reaction, right.

50
00:02:26.919 --> 00:02:32.240
<v Speaker 2>A slow accumulation of small, seemingly disconnected factors, A casual conversation,

51
00:02:32.719 --> 00:02:36.560
<v Speaker 2>a misnight of sleep, a flipped switch, all inevitably colliding.

52
00:02:36.960 --> 00:02:39.400
<v Speaker 1>Well, when a sixty thousand pound aircraft drops out of

53
00:02:39.439 --> 00:02:43.280
<v Speaker 1>the sky without forward momentum, investigators can't just guess what happened.

54
00:02:43.879 --> 00:02:46.680
<v Speaker 1>So to understand the scene and Clarence Center, we actually

55
00:02:46.719 --> 00:02:49.680
<v Speaker 1>need to rewind the clock a few hours, right, he do?

56
00:02:49.759 --> 00:02:51.599
<v Speaker 2>We have to go back to the flight's origin on

57
00:02:51.639 --> 00:02:54.919
<v Speaker 2>the tarmac in Newark, New Jersey, where the passengers were

58
00:02:55.319 --> 00:02:57.759
<v Speaker 2>enduring a grueling two hour weather.

59
00:02:57.599 --> 00:02:58.919
<v Speaker 1>Delay, which is miserable.

60
00:02:59.039 --> 00:03:01.919
<v Speaker 2>Oh, a two hour delay fundamentally shifts the mood in

61
00:03:01.960 --> 00:03:05.319
<v Speaker 2>a cabin, especially considering the actual flight time from Newark

62
00:03:05.319 --> 00:03:07.680
<v Speaker 2>to Buffalo is only scheduled for about fifty three minutes.

63
00:03:07.879 --> 00:03:10.560
<v Speaker 1>Wow, So they were delayed longer than the flight itself.

64
00:03:10.520 --> 00:03:14.680
<v Speaker 2>Way longer. And you have this Canadian made Bombardier Q

65
00:03:14.840 --> 00:03:19.759
<v Speaker 2>four hundred, which is a very capable, popular twin engine turboprop,

66
00:03:20.080 --> 00:03:22.759
<v Speaker 2>filled with forty five exhausted people.

67
00:03:23.639 --> 00:03:26.639
<v Speaker 1>You read through the passenger manifests and the personal stories

68
00:03:26.919 --> 00:03:28.719
<v Speaker 1>and it just breaks your heart. You have people like

69
00:03:29.039 --> 00:03:31.919
<v Speaker 1>Leise Kellner who was a law student studying down in Florida.

70
00:03:32.000 --> 00:03:33.639
<v Speaker 1>She just wanted to get home to Buffalo for a

71
00:03:33.719 --> 00:03:35.520
<v Speaker 1>quick visit to see her nieces and nephews.

72
00:03:35.639 --> 00:03:38.039
<v Speaker 2>Yeah, these passengers had just been peeling off the hours

73
00:03:38.039 --> 00:03:41.800
<v Speaker 2>in the terminal, drinking terrible airport coffee, desperate to get home,

74
00:03:42.280 --> 00:03:46.360
<v Speaker 2>and up front, the crew was feeling that exact same fatigue.

75
00:03:46.439 --> 00:03:50.280
<v Speaker 2>The aircraft is commanded by Captain Marvin Renslow alongside First

76
00:03:50.280 --> 00:03:53.479
<v Speaker 2>Officer Rebecca Shaw and First Officer Show is twenty four

77
00:03:53.520 --> 00:03:56.039
<v Speaker 2>years old, relatively new to the airline, flying with them

78
00:03:56.080 --> 00:03:59.280
<v Speaker 2>for just over a year. As they finally get airborne

79
00:03:59.280 --> 00:04:02.280
<v Speaker 2>and cruised through the night, heading northwest over upstate New York,

80
00:04:02.680 --> 00:04:05.919
<v Speaker 2>the atmosphere in the cockpit actually doesn't reflect the tension

81
00:04:05.919 --> 00:04:08.439
<v Speaker 2>of the weather outside. It's surprisingly relaxed.

82
00:04:08.719 --> 00:04:11.400
<v Speaker 1>The black box audio which well, we'll get into how

83
00:04:11.439 --> 00:04:14.719
<v Speaker 1>they recover that in a minute. It captures them just chatting.

84
00:04:14.879 --> 00:04:18.879
<v Speaker 1>They're talking about Shaw's career trajectory, debating whether she has

85
00:04:18.920 --> 00:04:22.279
<v Speaker 1>the hours to upgrade to a captain position, discussing quality

86
00:04:22.279 --> 00:04:23.879
<v Speaker 1>of life, the housing.

87
00:04:23.560 --> 00:04:25.160
<v Speaker 2>Market, complex, scheduling stuff.

88
00:04:25.240 --> 00:04:28.000
<v Speaker 1>Yeah, it honestly sounds like two co workers just passing

89
00:04:28.040 --> 00:04:30.920
<v Speaker 1>the time in a break room. And they keep this up.

90
00:04:30.920 --> 00:04:33.399
<v Speaker 1>As the flight nears its end, they descend to twenty

91
00:04:33.399 --> 00:04:36.800
<v Speaker 1>three hundred feet, they run through the standard approach checklists.

92
00:04:37.120 --> 00:04:39.240
<v Speaker 1>The landing gear clunks down right, and.

93
00:04:39.199 --> 00:04:41.959
<v Speaker 2>The flaps are extended to fifteen degrees, which alters the

94
00:04:41.959 --> 00:04:45.319
<v Speaker 2>wing shape to provide more lift at slower speeds. The

95
00:04:45.360 --> 00:04:48.040
<v Speaker 2>passengers can likely see the hazy lights of the Buffalo

96
00:04:48.040 --> 00:04:49.800
<v Speaker 2>suburbs through the clouds at this point.

97
00:04:49.879 --> 00:04:50.879
<v Speaker 1>So everything is normal.

98
00:04:51.000 --> 00:04:54.839
<v Speaker 2>Everything happening in that cockpit is consistent with a perfectly routine,

99
00:04:54.879 --> 00:04:59.399
<v Speaker 2>standard configuration for landing. The aircraft is functioning exactly as.

100
00:04:59.399 --> 00:05:02.800
<v Speaker 1>It should, and then the colmn just shatters out of

101
00:05:02.839 --> 00:05:06.360
<v Speaker 1>absolutely nowhere. The steering yolk in the cockpit the control

102
00:05:06.399 --> 00:05:08.839
<v Speaker 1>column begins to violently shake in the pilot's hands.

103
00:05:09.319 --> 00:05:13.399
<v Speaker 2>The aviation term for this is a stick shaker. It's

104
00:05:13.439 --> 00:05:16.199
<v Speaker 2>an intentional, highly aggressive mechanical warning.

105
00:05:16.439 --> 00:05:16.680
<v Speaker 1>Right.

106
00:05:16.759 --> 00:05:20.279
<v Speaker 2>It's loud, it vibrates intensely, and it's designed to physically

107
00:05:20.480 --> 00:05:25.040
<v Speaker 2>jar the pilots. It basically activates when the airplane's computers

108
00:05:25.040 --> 00:05:28.120
<v Speaker 2>detect that the aircraft is losing lift and is on

109
00:05:28.319 --> 00:05:31.560
<v Speaker 2>the absolute ragged edge of entering an aerodynamic stall.

110
00:05:31.759 --> 00:05:35.560
<v Speaker 1>Like it physically rattles your hands to communicate, hey, you

111
00:05:35.639 --> 00:05:38.120
<v Speaker 1>are about to fall out of the sky. Oh, exactly,

112
00:05:38.199 --> 00:05:42.199
<v Speaker 1>and the ensuing seconds are just sheer chaos. The audio

113
00:05:42.279 --> 00:05:45.920
<v Speaker 1>captures the captain fighting the controls First Officer Shaw frantically reacting,

114
00:05:46.240 --> 00:05:50.160
<v Speaker 1>but the Q four hundred slips entirely out of their command. Yeah,

115
00:05:50.160 --> 00:05:53.319
<v Speaker 1>it rolls, violently, pitches over and simply plumbus out of

116
00:05:53.319 --> 00:05:56.439
<v Speaker 1>the sky, dropping off the air traffic control radar in Buffalo.

117
00:05:56.439 --> 00:05:59.120
<v Speaker 2>In a matter of seconds, it entered an unrecoverable dive,

118
00:05:59.279 --> 00:06:01.959
<v Speaker 2>plummeting directly into that Clarence Center neighborhood.

119
00:06:02.040 --> 00:06:04.319
<v Speaker 1>I'm trying to wrap my head around the physics of this, though,

120
00:06:04.360 --> 00:06:06.319
<v Speaker 1>because if I'm driving my car on the highway, it

121
00:06:06.360 --> 00:06:09.199
<v Speaker 1>doesn't just spontaneously lose all this momentum and roll into

122
00:06:09.199 --> 00:06:11.720
<v Speaker 1>a ditch unless the engine completely dies or I slam

123
00:06:11.720 --> 00:06:14.040
<v Speaker 1>on the brakes. Yeah, something has to actively kill that

124
00:06:14.120 --> 00:06:14.759
<v Speaker 1>forward energy.

125
00:06:14.839 --> 00:06:15.079
<v Speaker 2>Yeah.

126
00:06:15.079 --> 00:06:18.040
<v Speaker 1>So investigators arrive at a scene that is nothing but

127
00:06:18.199 --> 00:06:22.920
<v Speaker 1>burning rubble. Where do they even begin to look for that?

128
00:06:23.079 --> 00:06:26.920
<v Speaker 2>Cause, well, they desperately need the flight data. When NTSB

129
00:06:27.040 --> 00:06:31.160
<v Speaker 2>investigators like Clint Crookshanks first walked onto the scene, they

130
00:06:31.199 --> 00:06:35.079
<v Speaker 2>were stepping into an absolute nightmare scenario. I bet the

131
00:06:35.120 --> 00:06:38.360
<v Speaker 2>wreckage had completely collapsed into a basement under ten feet

132
00:06:38.399 --> 00:06:42.040
<v Speaker 2>of smoldering house debris. The house's natural gas line had

133
00:06:42.079 --> 00:06:46.480
<v Speaker 2>actually ruptured and was continuously feeding the flames, making the

134
00:06:46.519 --> 00:06:48.399
<v Speaker 2>center of the wreckage an active inferno.

135
00:06:48.600 --> 00:06:50.519
<v Speaker 1>So the very evidence they need to solve the mystery

136
00:06:50.639 --> 00:06:52.399
<v Speaker 1>is literally melting in front of their.

137
00:06:52.240 --> 00:06:57.360
<v Speaker 2>Eyes exactly Ordinarily, standard safety protocols dictate that investigators wait

138
00:06:57.399 --> 00:06:59.759
<v Speaker 2>for a fire to completely burn itself out before they

139
00:07:00.000 --> 00:07:02.439
<v Speaker 2>aproach to the center of a crash. The environment is

140
00:07:02.480 --> 00:07:05.399
<v Speaker 2>just too toxic and volatile, right, obviously, But they realized

141
00:07:05.439 --> 00:07:08.839
<v Speaker 2>the black boxes, the flight data recorder, and the cockpit

142
00:07:08.920 --> 00:07:12.279
<v Speaker 2>voice recorder were located in the tail section of the airplane,

143
00:07:12.399 --> 00:07:15.199
<v Speaker 2>and that tail section was acting like a chimney, sitting

144
00:07:15.240 --> 00:07:17.959
<v Speaker 2>directly over the hottest part of the fire. Oh man,

145
00:07:18.040 --> 00:07:20.439
<v Speaker 2>the data was highly perishable.

146
00:07:20.040 --> 00:07:23.199
<v Speaker 1>So the urgency must have been frantic. The NTSB actually

147
00:07:23.279 --> 00:07:26.120
<v Speaker 1>coordinated with the local fire department to bring in a

148
00:07:26.120 --> 00:07:27.040
<v Speaker 1>massive chopsaw.

149
00:07:27.199 --> 00:07:28.000
<v Speaker 2>Yeah, chop saw.

150
00:07:28.279 --> 00:07:31.079
<v Speaker 1>They waited the heat and cut a physical hole straight

151
00:07:31.120 --> 00:07:34.560
<v Speaker 1>through the smoldering composite materials of the fuselage just to

152
00:07:34.639 --> 00:07:38.160
<v Speaker 1>rip those recorders out before the internal memory boards melted.

153
00:07:37.920 --> 00:07:42.680
<v Speaker 2>Which is incredible, and the extraction was successful preserving the data,

154
00:07:43.519 --> 00:07:47.759
<v Speaker 2>but the broader recovery was this painstaking, grueling process. The

155
00:07:47.839 --> 00:07:51.800
<v Speaker 2>local authority is actually brought in forensic anthropology graduate students

156
00:07:51.800 --> 00:07:52.439
<v Speaker 2>to assist.

157
00:07:52.519 --> 00:07:52.839
<v Speaker 1>Wow.

158
00:07:53.199 --> 00:07:55.680
<v Speaker 2>Yeah, these young students were literally on their hands and

159
00:07:55.759 --> 00:07:59.639
<v Speaker 2>knees in the freezing wet snow, using small masonry trowels

160
00:07:59.639 --> 00:08:03.319
<v Speaker 2>and hands brooms to meticulously sift through the ash. They

161
00:08:03.319 --> 00:08:05.839
<v Speaker 2>had to separate the aircraft components from the remnants of

162
00:08:05.879 --> 00:08:09.439
<v Speaker 2>the house, all while respectfully recovering the victims.

163
00:08:09.120 --> 00:08:12.639
<v Speaker 1>Which eventually allowed the NTSB structural engineers to step back

164
00:08:12.680 --> 00:08:16.360
<v Speaker 1>and do something called the four corners check. Now, I imagine

165
00:08:16.279 --> 00:08:18.439
<v Speaker 1>that just means finding the furthest points of the plane

166
00:08:18.439 --> 00:08:20.120
<v Speaker 1>to figure out the size of the impact crater.

167
00:08:20.399 --> 00:08:24.560
<v Speaker 2>It's actually a fundamental diagnostic tool. By locating the nose,

168
00:08:24.800 --> 00:08:27.480
<v Speaker 2>the tail, and the specific tips of both the left

169
00:08:27.480 --> 00:08:31.279
<v Speaker 2>and right wings, investigators can map the structural integrity of

170
00:08:31.319 --> 00:08:33.080
<v Speaker 2>the aircraft prior to impact.

171
00:08:33.200 --> 00:08:33.759
<v Speaker 1>Oh I see.

172
00:08:33.960 --> 00:08:36.519
<v Speaker 2>It took days of scraping through the ice and ash,

173
00:08:36.600 --> 00:08:39.399
<v Speaker 2>but they located all four points within the immediate footprint

174
00:08:39.399 --> 00:08:39.879
<v Speaker 2>of the house.

175
00:08:39.960 --> 00:08:43.399
<v Speaker 1>Wow. Okay, So that definitively proved the plane did not

176
00:08:43.519 --> 00:08:47.039
<v Speaker 1>suffer an inflight breakup. No doors blew off, no wings

177
00:08:47.080 --> 00:08:49.919
<v Speaker 1>snapped in the sky. The Q four hundred was entirely

178
00:08:49.960 --> 00:08:53.000
<v Speaker 1>whole and mechanically intact right up until the millisecond it

179
00:08:53.080 --> 00:08:53.559
<v Speaker 1>hit the ground.

180
00:08:53.600 --> 00:08:54.000
<v Speaker 2>That's right.

181
00:08:54.039 --> 00:08:56.200
<v Speaker 1>Okay, So we have a mechanically whole airplane that falls

182
00:08:56.200 --> 00:08:59.399
<v Speaker 1>from the sky in February. I think anyone who flies

183
00:08:59.399 --> 00:09:02.399
<v Speaker 1>in winter mediately thinks of the same culprit ice ice.

184
00:09:02.720 --> 00:09:05.399
<v Speaker 1>And when you read the transcripts from that recovered Cockpait

185
00:09:05.480 --> 00:09:09.399
<v Speaker 1>voice recorder, it feels like they found the smoking gun immediately,

186
00:09:09.759 --> 00:09:12.240
<v Speaker 1>I mean six minutes before the crash. First Officer Shaw says,

187
00:09:12.559 --> 00:09:15.600
<v Speaker 1>is that ice on the windshield? Captain Renslow replies, Oh yeah,

188
00:09:15.679 --> 00:09:16.480
<v Speaker 1>it's lots of ice.

189
00:09:17.200 --> 00:09:19.440
<v Speaker 2>Shaw I even mentioned she has never flown in icing

190
00:09:19.480 --> 00:09:21.879
<v Speaker 2>conditions this severe in her entire career.

191
00:09:22.279 --> 00:09:25.519
<v Speaker 1>Right, So, ice is an insidious threat in aviation. But

192
00:09:25.559 --> 00:09:27.960
<v Speaker 1>people often assume that ice brings an airplane down simply

193
00:09:27.960 --> 00:09:30.279
<v Speaker 1>because it makes the airframe too heavy. That's always what

194
00:09:30.360 --> 00:09:33.320
<v Speaker 1>I pictured, you know, like a huge block of ice

195
00:09:33.360 --> 00:09:36.159
<v Speaker 1>forms the plane weighs an extra two tons, and the

196
00:09:36.159 --> 00:09:37.279
<v Speaker 1>engines just can't pull it.

197
00:09:37.559 --> 00:09:40.480
<v Speaker 2>The weight is a factor, sure, but the true danger

198
00:09:40.720 --> 00:09:42.159
<v Speaker 2>is aerodynamic disruption.

199
00:09:42.440 --> 00:09:42.759
<v Speaker 1>Okay.

200
00:09:42.919 --> 00:09:46.879
<v Speaker 2>See, an airplane wing generates lyft because of its very specific,

201
00:09:47.240 --> 00:09:51.799
<v Speaker 2>meticulously engineered curved shape. As air travels over that curve,

202
00:09:51.960 --> 00:09:55.440
<v Speaker 2>it creates low pressure above the wing, effectively sucking the

203
00:09:55.440 --> 00:09:56.320
<v Speaker 2>plane into the sky.

204
00:09:56.559 --> 00:09:57.759
<v Speaker 1>Right aerodynamics.

205
00:09:57.919 --> 00:10:01.159
<v Speaker 2>But when super cooled water droplets strike the leading edge

206
00:10:01.200 --> 00:10:05.200
<v Speaker 2>of a wing, they freeze instantly, creating these jagged, irregular

207
00:10:05.240 --> 00:10:09.000
<v Speaker 2>horns of ice. This utterly destroys the smooth flow of air.

208
00:10:09.320 --> 00:10:12.919
<v Speaker 2>The lift just evaporates, regardless of how powerful the engines are.

209
00:10:13.000 --> 00:10:15.759
<v Speaker 1>But wait, commercial turbo props that fly in the Northeast

210
00:10:15.759 --> 00:10:17.840
<v Speaker 1>are built for this. They have de icing boots, yes

211
00:10:17.840 --> 00:10:21.639
<v Speaker 1>they do. These are thick, durable rubber bladders running along

212
00:10:21.639 --> 00:10:23.759
<v Speaker 1>the front edges of the wings and the tail when

213
00:10:23.799 --> 00:10:27.919
<v Speaker 1>the pilots flip a switch. Pneumatic valves take hot, highly compressed,

214
00:10:27.960 --> 00:10:31.440
<v Speaker 1>bleed air straight from the engines and inflate these rubber

215
00:10:31.440 --> 00:10:35.480
<v Speaker 1>bladders like balloons. They physically expand and crack the ice

216
00:10:35.519 --> 00:10:37.759
<v Speaker 1>off the metal, so it just blows away in the wind.

217
00:10:37.960 --> 00:10:41.759
<v Speaker 2>And investigators naturally suspected a failure of this system. They

218
00:10:41.879 --> 00:10:44.720
<v Speaker 2>dug through the molten aluminum in the basement and successfully

219
00:10:44.720 --> 00:10:47.840
<v Speaker 2>recovered five of the six pneumatic de icing valves.

220
00:10:47.960 --> 00:10:48.559
<v Speaker 1>Did they work?

221
00:10:49.120 --> 00:10:52.240
<v Speaker 2>They send them to a specialized lab, tested their electrical

222
00:10:52.279 --> 00:10:55.879
<v Speaker 2>continuity and pressure thresholds, and discovered every single one of

223
00:10:55.919 --> 00:10:59.960
<v Speaker 2>them was functioning flawlessly. The de icing boots were actively warm.

224
00:11:00.360 --> 00:11:02.360
<v Speaker 1>Okay, And this is where the data from the flight

225
00:11:02.440 --> 00:11:06.720
<v Speaker 1>data recorder drops another massive twist into the investigation. The

226
00:11:06.840 --> 00:11:09.559
<v Speaker 1>NTSB ran the math on the specific weight of the

227
00:11:09.600 --> 00:11:13.000
<v Speaker 1>aircraft and the weather conditions that night. They calculated that

228
00:11:13.000 --> 00:11:15.919
<v Speaker 1>the Q four hundred's absolute minimum stall speed you know,

229
00:11:15.960 --> 00:11:18.159
<v Speaker 1>the speed at which the wings can no longer generate

230
00:11:18.279 --> 00:11:20.879
<v Speaker 1>enough lift to keep flying, was about one hundred and

231
00:11:20.879 --> 00:11:25.159
<v Speaker 1>eleven knots. But when that violent stickshaker warning activated, the

232
00:11:25.240 --> 00:11:27.399
<v Speaker 1>data showed the plane was flying at one hundred and

233
00:11:27.399 --> 00:11:29.039
<v Speaker 1>thirty one knots.

234
00:11:28.799 --> 00:11:31.600
<v Speaker 2>The aircraft was cruising a full twenty knots above the

235
00:11:31.679 --> 00:11:36.000
<v Speaker 2>danger zone. By analyzing the engine torque required to maintain

236
00:11:36.000 --> 00:11:38.759
<v Speaker 2>at totter and thirty one knots, investigators proved the plane

237
00:11:38.840 --> 00:11:41.480
<v Speaker 2>was not bogged down by ice. It had a very

238
00:11:41.600 --> 00:11:45.600
<v Speaker 2>manageable normal accumulation that the boots were handling just fine.

239
00:11:45.799 --> 00:11:46.279
<v Speaker 1>Wow.

240
00:11:46.440 --> 00:11:49.320
<v Speaker 2>The terrifying realization was that when the stick shaker went off,

241
00:11:49.480 --> 00:11:53.039
<v Speaker 2>the airplane was not actually stalling. It was flying perfectly fine.

242
00:11:53.240 --> 00:11:55.759
<v Speaker 1>Okay, So if the plane was installing and the ice

243
00:11:55.879 --> 00:11:59.240
<v Speaker 1>wasn't dragging it down, why did the onboard computer scream

244
00:11:59.279 --> 00:12:01.120
<v Speaker 1>at the pilot's they were falling out of the sky.

245
00:12:01.360 --> 00:12:05.159
<v Speaker 2>The answer lies in a tiny specific toggle switch located

246
00:12:05.200 --> 00:12:07.679
<v Speaker 2>on the overhead panel in the Q four hundreds cockpit.

247
00:12:07.840 --> 00:12:09.679
<v Speaker 2>It's known as the reference speed switch.

248
00:12:09.799 --> 00:12:12.519
<v Speaker 1>Now, I would guess that flipping this switch basically tells

249
00:12:12.519 --> 00:12:15.440
<v Speaker 1>the computer, hey, we're in a storm, be extra sensitive

250
00:12:15.480 --> 00:12:16.039
<v Speaker 1>to stalls.

251
00:12:16.399 --> 00:12:20.759
<v Speaker 2>That is the exact underlying logic. When pilots enter known

252
00:12:21.000 --> 00:12:25.799
<v Speaker 2>icing conditions, Standard operating procedure mandates they move this switch

253
00:12:25.919 --> 00:12:29.440
<v Speaker 2>to the increase position. Because even a thin layer of

254
00:12:29.480 --> 00:12:31.759
<v Speaker 2>ice can slightly increase the speed at which a plane

255
00:12:31.759 --> 00:12:34.879
<v Speaker 2>will stall. This switch acts as a safety.

256
00:12:34.559 --> 00:12:35.840
<v Speaker 1>Buffer, makes sense.

257
00:12:36.159 --> 00:12:39.600
<v Speaker 2>It artificially raises the threshold for the warning systems. It

258
00:12:39.639 --> 00:12:42.279
<v Speaker 2>tells the computer to trigger the stick shaker much earlier

259
00:12:42.360 --> 00:12:44.679
<v Speaker 2>than it normally would, ensuring the pilots have plenty of

260
00:12:44.720 --> 00:12:46.639
<v Speaker 2>time to react and keep their air speed up.

261
00:12:46.879 --> 00:12:49.759
<v Speaker 1>Okay, so the system did exactly what it was programmed

262
00:12:49.759 --> 00:12:53.240
<v Speaker 1>to do. Investigators sifted through the charred remains of the cockpit,

263
00:12:53.679 --> 00:12:56.679
<v Speaker 1>found the outs protection panel and confirmed the switch had

264
00:12:56.679 --> 00:13:00.120
<v Speaker 1>been tuggled to increase and because it was on the

265
00:13:00.120 --> 00:13:03.720
<v Speaker 1>plane's flight computer recalculated the safety margins and displayed a

266
00:13:03.759 --> 00:13:06.240
<v Speaker 1>series of bright red warning bars on the air speed

267
00:13:06.279 --> 00:13:08.919
<v Speaker 1>indicators right in the pilot's line of sight.

268
00:13:09.200 --> 00:13:13.399
<v Speaker 2>The visual warnings were glaring, but the crew missed them entirely.

269
00:13:13.440 --> 00:13:14.559
<v Speaker 1>They just didn't see them.

270
00:13:14.879 --> 00:13:18.480
<v Speaker 2>No, As they lowered the landing gear and extended the flaps,

271
00:13:18.840 --> 00:13:21.960
<v Speaker 2>the increased drag naturally caused the airplane to slow down.

272
00:13:22.559 --> 00:13:26.840
<v Speaker 2>The speed decayed, dropping toward that artificially raised safety threshold,

273
00:13:27.159 --> 00:13:30.320
<v Speaker 2>and because they hadn't noticed the red bars, the sudden,

274
00:13:30.519 --> 00:13:34.240
<v Speaker 2>violent activation of the stick shaker caught them completely off guard.

275
00:13:34.080 --> 00:13:37.679
<v Speaker 1>Which triggers the most horrific ten seconds of the entire flight.

276
00:13:38.000 --> 00:13:42.120
<v Speaker 1>The yoke starts aggressively shaking, rattling their teeth, and this

277
00:13:42.159 --> 00:13:45.519
<v Speaker 1>is where the tragedy compounds. Because the standard procedure for

278
00:13:45.559 --> 00:13:49.399
<v Speaker 1>recovering from a stall warning is aviation one oh one.

279
00:13:49.440 --> 00:13:52.759
<v Speaker 1>Every student pilot learns this on day one. You push

280
00:13:52.840 --> 00:13:54.679
<v Speaker 1>the nose of the aircraft down toward the ground to

281
00:13:54.679 --> 00:13:57.919
<v Speaker 1>gain speed, to get air flowing rapidly back over the wings. Right,

282
00:13:58.080 --> 00:14:00.799
<v Speaker 1>But Captain Ronslow does something completely inexplicable.

283
00:14:00.840 --> 00:14:03.039
<v Speaker 2>The flight data recorder captures both the position of the

284
00:14:03.039 --> 00:14:05.759
<v Speaker 2>control column and the physical pounds of force applied to

285
00:14:05.840 --> 00:14:09.600
<v Speaker 2>it when the shaker activated. Captain Renslow pulled backward on

286
00:14:09.639 --> 00:14:13.159
<v Speaker 2>the yoke. He pulled with tremendous physical force, fighting the

287
00:14:13.200 --> 00:14:16.200
<v Speaker 2>airplane's own automated attempts to push the nose down.

288
00:14:16.279 --> 00:14:18.639
<v Speaker 1>He's pitching the nose of the sixty thousand pound airplane

289
00:14:18.720 --> 00:14:19.399
<v Speaker 1>up into the sky.

290
00:14:19.759 --> 00:14:22.720
<v Speaker 2>By aiming the nose up while they were already flying slowly,

291
00:14:23.120 --> 00:14:26.519
<v Speaker 2>he rapidly bled off whatever Ford momentum and air speed

292
00:14:26.559 --> 00:14:29.320
<v Speaker 2>they still had. He was forcing the aircraft into the

293
00:14:29.360 --> 00:14:31.720
<v Speaker 2>exact aerodynamic stall. The computer was trying to.

294
00:14:31.679 --> 00:14:34.840
<v Speaker 1>Prevent, and First Officer Shaw, sitting in the right seat,

295
00:14:34.919 --> 00:14:38.960
<v Speaker 1>trying to fix the chaos, reaches over and retracts the flaps.

296
00:14:38.600 --> 00:14:41.399
<v Speaker 2>Which is terrible because the flaps were providing the crucial

297
00:14:41.399 --> 00:14:45.480
<v Speaker 2>extra lift keeping them airborne at that low speed. Retracting

298
00:14:45.480 --> 00:14:48.480
<v Speaker 2>them was effectively pulling the rug out from under the aircraft.

299
00:14:48.519 --> 00:14:51.200
<v Speaker 2>Oh my god, you have a captain aggressively pitching the

300
00:14:51.240 --> 00:14:55.000
<v Speaker 2>nose up, destroying their speed, and a first officer stripping

301
00:14:55.000 --> 00:14:57.480
<v Speaker 2>away their lift. If they had taken their hands off

302
00:14:57.480 --> 00:15:01.320
<v Speaker 2>the controls entirely or simply push forward, the Q four

303
00:15:01.399 --> 00:15:05.480
<v Speaker 2>hundred would have comfortably recovered with hundreds of feet to spare. Instead,

304
00:15:05.799 --> 00:15:08.759
<v Speaker 2>these two professionals took a healthy airplane and muscled it

305
00:15:08.840 --> 00:15:10.120
<v Speaker 2>into a fatal plunge.

306
00:15:10.200 --> 00:15:13.279
<v Speaker 1>This is the core mystery of flight three four oh seven.

307
00:15:13.919 --> 00:15:17.679
<v Speaker 1>Why would two individuals who have dedicated their lives to aviation,

308
00:15:18.080 --> 00:15:21.799
<v Speaker 1>sitting inside a multimillion dollar machine commit such a fundamental

309
00:15:21.919 --> 00:15:25.960
<v Speaker 1>backward error. To figure that out, the NTSB investigators had

310
00:15:25.960 --> 00:15:28.639
<v Speaker 1>to leave the craft site. They had to turn into

311
00:15:28.679 --> 00:15:31.799
<v Speaker 1>detectives and track the daily lives of Marvin Renslow and

312
00:15:31.799 --> 00:15:34.519
<v Speaker 1>Rebeccah Shaw for the seventy two hours leading up to

313
00:15:34.519 --> 00:15:35.200
<v Speaker 1>the crash.

314
00:15:35.000 --> 00:15:38.840
<v Speaker 2>And that biographical timeline exposed the dark, hidden underbelly of

315
00:15:38.879 --> 00:15:42.279
<v Speaker 2>regional airline economics. In two thousand and nine, Continental Connection

316
00:15:42.320 --> 00:15:44.559
<v Speaker 2>Flight three four to seven was not actually flown by

317
00:15:44.600 --> 00:15:48.559
<v Speaker 2>Continental Airlines. It was outsourced to a smaller regional carrier

318
00:15:48.639 --> 00:15:52.720
<v Speaker 2>called Colgan Air. Right these regional carriers operate roughly half

319
00:15:52.759 --> 00:15:55.600
<v Speaker 2>of all domestic passenger flights in the United States, flying

320
00:15:55.639 --> 00:15:58.120
<v Speaker 2>the exact same routes as the majors, but their financial

321
00:15:58.120 --> 00:16:00.559
<v Speaker 2>structures and working conditions were ratic different.

322
00:16:00.639 --> 00:16:04.080
<v Speaker 1>The pay disparity is staggering. To look at Captain Renslaw,

323
00:16:04.080 --> 00:16:06.440
<v Speaker 1>the man holding the lives of fifty people in his hands,

324
00:16:06.639 --> 00:16:09.159
<v Speaker 1>was making about sixty thousand dollars a year. The first

325
00:16:09.159 --> 00:16:12.559
<v Speaker 1>officer shaw salary was horrifying. She was making under sixteen

326
00:16:12.600 --> 00:16:13.559
<v Speaker 1>thousand dollars a year.

327
00:16:13.799 --> 00:16:16.559
<v Speaker 2>She was earning significantly less than a fast food manager

328
00:16:16.679 --> 00:16:19.120
<v Speaker 2>or a city bus driver at the time, yet she

329
00:16:19.360 --> 00:16:23.759
<v Speaker 2>was responsible for navigating a complex turbo crop through winter storms.

330
00:16:23.799 --> 00:16:27.360
<v Speaker 1>Because they were paid poverty level wages, neither pilot could

331
00:16:27.360 --> 00:16:30.440
<v Speaker 1>actually afford to live anywhere near their assigned base in Newark,

332
00:16:30.559 --> 00:16:34.759
<v Speaker 1>New Jersey. The NTSB subpoened their phone records and credit

333
00:16:34.759 --> 00:16:38.600
<v Speaker 1>cards to trace their commutes. Shaw lived across the entire

334
00:16:38.639 --> 00:16:41.600
<v Speaker 1>country in Seattle, Yeah. To get to work for this shift,

335
00:16:41.960 --> 00:16:44.360
<v Speaker 1>she rode in a jump seat on a FedEx cargo

336
00:16:44.399 --> 00:16:48.159
<v Speaker 1>plane overnight, flying from Seattle to Memphis, then Memphis to

337
00:16:48.200 --> 00:16:49.519
<v Speaker 1>Newark just to clock in.

338
00:16:49.759 --> 00:16:52.519
<v Speaker 2>And Captain Renslow was based in Florida. He had flown

339
00:16:52.559 --> 00:16:54.240
<v Speaker 2>up to Newark worked for a couple of days, and

340
00:16:54.320 --> 00:16:57.039
<v Speaker 2>investigators discovered that on the night before the crash, he

341
00:16:57.080 --> 00:16:59.320
<v Speaker 2>didn't go to a hotel. He couldn't afford a fifty

342
00:16:59.320 --> 00:16:59.919
<v Speaker 2>dollars motel.

343
00:17:00.440 --> 00:17:00.879
<v Speaker 1>Wow.

344
00:17:01.159 --> 00:17:04.519
<v Speaker 2>He was seen sleeping on a sofa in the airline's bustling,

345
00:17:04.599 --> 00:17:06.519
<v Speaker 2>noisy crew lounge at the airport.

346
00:17:06.720 --> 00:17:09.119
<v Speaker 1>Sleeping on a couch in a room with fluorescent lights

347
00:17:09.160 --> 00:17:12.160
<v Speaker 1>and people constantly walking in and out. That's insane.

348
00:17:12.359 --> 00:17:15.839
<v Speaker 2>Sleeping in the lounge was technically a violation of company policy,

349
00:17:16.240 --> 00:17:19.960
<v Speaker 2>but the NTSB found it was an open secret. Management

350
00:17:20.000 --> 00:17:22.279
<v Speaker 2>basically looked the other way because everyone knew the pilots

351
00:17:22.319 --> 00:17:25.759
<v Speaker 2>couldn't afford lodging. By the time Shawn Renslow strapped into

352
00:17:25.799 --> 00:17:28.240
<v Speaker 2>the cockpit of flight three four oh seven, they were

353
00:17:28.240 --> 00:17:33.200
<v Speaker 2>both profoundly dangerously fatigued. Their circadian rhythms were wrecked, and

354
00:17:33.240 --> 00:17:35.599
<v Speaker 2>they had accumulated massive sleep.

355
00:17:35.359 --> 00:17:38.640
<v Speaker 1>Debt, and that profound fatigue acts like a poison on

356
00:17:38.680 --> 00:17:42.119
<v Speaker 1>a pilot's cognitive abilities. It explains the conversation on the

357
00:17:42.119 --> 00:17:45.720
<v Speaker 1>cockpit voice recorder we discussed earlier. They weren't just being friendly.

358
00:17:45.839 --> 00:17:48.680
<v Speaker 1>Chatting casually about Shaw's career while descending through ten thousand

359
00:17:48.720 --> 00:17:51.880
<v Speaker 1>feet is a direct violation of a federal law known

360
00:17:51.920 --> 00:17:53.839
<v Speaker 1>as the Sterile Cockpit Rule right.

361
00:17:53.839 --> 00:17:56.799
<v Speaker 2>The Steri Cockpit Rule mandates that during critical phases of

362
00:17:56.839 --> 00:18:01.200
<v Speaker 2>flight so taxi takeoff, landing, and all all operations below

363
00:18:01.319 --> 00:18:05.119
<v Speaker 2>ten thousand feet, pilots are strictly prohibited from engaging in

364
00:18:05.200 --> 00:18:08.519
<v Speaker 2>any non essential conversation. No talking about the weekend, no

365
00:18:08.599 --> 00:18:11.920
<v Speaker 2>reading newspapers, nothing. It's designed to ensure one hundred percent

366
00:18:11.960 --> 00:18:14.519
<v Speaker 2>of their cognitive bandwidth is focused on the instruments and

367
00:18:14.559 --> 00:18:15.960
<v Speaker 2>the aircraft's energy state.

368
00:18:16.240 --> 00:18:19.039
<v Speaker 1>But when you're operating on three hours of awful sleep,

369
00:18:19.640 --> 00:18:24.359
<v Speaker 1>your brain loses the ability to maintain broad situational awareness.

370
00:18:24.920 --> 00:18:27.880
<v Speaker 1>You get tunnel vision. You focus on the conversation just

371
00:18:27.920 --> 00:18:30.480
<v Speaker 1>to stay awake, but you lose track of the airplane

372
00:18:31.079 --> 00:18:33.759
<v Speaker 1>because they were chatting and distracted. They ran through their

373
00:18:33.839 --> 00:18:37.359
<v Speaker 1>landing checklists late because they were rushing to catch up.

374
00:18:37.599 --> 00:18:41.400
<v Speaker 1>Their eyes glossed right over the bright red warning bars

375
00:18:41.440 --> 00:18:44.359
<v Speaker 1>on their screens, indicating their speed was decaying.

376
00:18:44.799 --> 00:18:48.240
<v Speaker 2>It is a textbook cascade of human factors. When the

377
00:18:48.240 --> 00:18:53.200
<v Speaker 2>stickshaker finally erupts, shattering that relaxed atmosphere, their sleep deprived

378
00:18:53.240 --> 00:18:57.079
<v Speaker 2>brains suffer a massive psychological phenomenon known as the startle effect.

379
00:18:57.200 --> 00:19:00.319
<v Speaker 2>The startle effect right when a human being is yearly

380
00:19:00.359 --> 00:19:04.559
<v Speaker 2>fatigued and suddenly frightened, The brain bypasses higher order logical

381
00:19:04.599 --> 00:19:07.400
<v Speaker 2>training like pushed the nose down to gain speed, and

382
00:19:07.480 --> 00:19:12.400
<v Speaker 2>defaults to sheer. Panic, survival instinct, and biological instinct dictates

383
00:19:12.400 --> 00:19:14.279
<v Speaker 2>that if you feel like you were falling toward the ground,

384
00:19:14.359 --> 00:19:16.039
<v Speaker 2>you pull back to get away from it.

385
00:19:16.039 --> 00:19:19.519
<v Speaker 1>It's an absolutely heartbreaking realization. The plane didn't fail them.

386
00:19:19.759 --> 00:19:23.359
<v Speaker 1>The system failed them. The regional airline industry's economic model

387
00:19:23.400 --> 00:19:27.160
<v Speaker 1>prioritized cheap tickets, overrested pilots, and fifty people paid the

388
00:19:27.240 --> 00:19:30.400
<v Speaker 1>ultimate price. But the story of Flight three twenty four

389
00:19:30.400 --> 00:19:32.759
<v Speaker 1>oh seven didn't end in that basement and Clarence Center.

390
00:19:33.119 --> 00:19:35.119
<v Speaker 1>The families of those victims made sure of it.

391
00:19:35.400 --> 00:19:38.240
<v Speaker 2>They did. The families refused to accept a report that

392
00:19:38.319 --> 00:19:42.279
<v Speaker 2>simply blamed pilot error. John Kellner, the father of the

393
00:19:42.359 --> 00:19:46.240
<v Speaker 2>law student Elise Tilmer, along with dozens of other grieving relatives,

394
00:19:46.680 --> 00:19:51.039
<v Speaker 2>organized an incredible grassroots movement. They turned their profound grief

395
00:19:51.119 --> 00:19:53.920
<v Speaker 2>into fierce, relentless political advocacy.

396
00:19:54.279 --> 00:19:57.240
<v Speaker 1>Right they took countless trips to Washington, d C. Practically

397
00:19:57.319 --> 00:19:59.799
<v Speaker 1>living in the halls of Congress, demanding systemic change.

398
00:20:00.000 --> 00:20:02.640
<v Speaker 2>Oh pressure was immovable, and they won. The Flight three

399
00:20:02.799 --> 00:20:05.440
<v Speaker 2>four oh seven families forced the US Congress to pass

400
00:20:05.480 --> 00:20:09.440
<v Speaker 2>the Airline's Safety and Federal Aviation Administration Extension Act of

401
00:20:09.440 --> 00:20:13.880
<v Speaker 2>twenty ten, which was huge. This sweeping legislation fundamentally rewrote

402
00:20:13.920 --> 00:20:18.240
<v Speaker 2>the rules of commercial aviation. It mandated that first officers

403
00:20:18.319 --> 00:20:22.079
<v Speaker 2>must have a minimum of fifteen hundred hours of flight experience,

404
00:20:22.480 --> 00:20:25.160
<v Speaker 2>up from just two hundred and fifty hours, before they

405
00:20:25.160 --> 00:20:27.960
<v Speaker 2>can even sit in the right seat of a commercial airliner.

406
00:20:28.359 --> 00:20:32.240
<v Speaker 2>It also forced airlines to completely overhaul their duty hour rules,

407
00:20:32.480 --> 00:20:34.759
<v Speaker 2>severely limiting how long a pilot can be kept on

408
00:20:34.880 --> 00:20:37.680
<v Speaker 2>duty without mandatory protected rest periods.

409
00:20:37.720 --> 00:20:40.920
<v Speaker 1>But the aviation industry recognized that simply writing new rules

410
00:20:40.920 --> 00:20:44.079
<v Speaker 1>about sleep wasn't enough, right, They had to actually engineer

411
00:20:44.200 --> 00:20:48.839
<v Speaker 1>solutions to monitor human consciousness. This crash became a catalyst

412
00:20:48.839 --> 00:20:52.200
<v Speaker 1>for incredible research by human factors engineers exactly, So what

413
00:20:52.240 --> 00:20:54.559
<v Speaker 1>does that research actually look like in practice? Today?

414
00:20:54.680 --> 00:20:57.400
<v Speaker 2>Researchers like Thomas Schnell at the University of Iowa are

415
00:20:57.440 --> 00:21:00.880
<v Speaker 2>running advanced flight simulators where pilots are essentially wired into

416
00:21:00.920 --> 00:21:04.440
<v Speaker 2>neurocognitive arrays. They aren't just watching how the pilot flies,

417
00:21:04.480 --> 00:21:08.319
<v Speaker 2>They're monitoring the pilot's biology. They use EKGs to track

418
00:21:08.359 --> 00:21:12.200
<v Speaker 2>heart rate variability. They use sophisticated eye tracking cameras to

419
00:21:12.279 --> 00:21:15.799
<v Speaker 2>monitor sacades, the rapid darting movements of the eyes.

420
00:21:16.119 --> 00:21:19.000
<v Speaker 1>Right, because when you are alert, your eyes are constantly

421
00:21:19.000 --> 00:21:22.960
<v Speaker 1>scanning the instruments, checking speed, altitude.

422
00:21:22.359 --> 00:21:26.359
<v Speaker 2>And heading exactly. And when you become drowsy, that gaze

423
00:21:26.400 --> 00:21:29.680
<v Speaker 2>becomes stagnant. You stare at one instrument for too long.

424
00:21:30.240 --> 00:21:32.960
<v Speaker 2>They even map brain wave activity to watch for the

425
00:21:32.960 --> 00:21:36.440
<v Speaker 2>intrusion of alpha waves, which indicate a brains slipping into

426
00:21:36.440 --> 00:21:37.839
<v Speaker 2>boredom and micro sleeps.

427
00:21:38.319 --> 00:21:41.920
<v Speaker 1>They're literally teaching the airplane's computer how to measure human boredom.

428
00:21:42.039 --> 00:21:44.799
<v Speaker 2>The ultimate goal is to integrate these sensors into the

429
00:21:44.799 --> 00:21:48.319
<v Speaker 2>flight decks of the future, creating an advanced driver assists

430
00:21:48.319 --> 00:21:52.480
<v Speaker 2>system for airplanes. If the aircraft detects the pilot's gaze

431
00:21:52.480 --> 00:21:56.319
<v Speaker 2>fixating or they're cognitive load dropping dangerously low during a

432
00:21:56.359 --> 00:21:59.799
<v Speaker 2>critical phase of flight, the plane itself can intervene. Wow,

433
00:22:00.000 --> 00:22:03.279
<v Speaker 2>you might change the ambient lighting, trigger an auditory alarm,

434
00:22:03.440 --> 00:22:05.880
<v Speaker 2>or eventually refuse to let the pilot make a dangerous

435
00:22:05.880 --> 00:22:06.640
<v Speaker 2>control input.

436
00:22:06.880 --> 00:22:09.200
<v Speaker 1>It's incredible to think about the aircraft acting as an

437
00:22:09.200 --> 00:22:13.039
<v Speaker 1>active safeguard against our own biological limits. Next time you

438
00:22:13.079 --> 00:22:14.920
<v Speaker 1>settle into your seat on a flight and you hear

439
00:22:14.960 --> 00:22:17.559
<v Speaker 1>that familiar ding of the seatbelt sign, look toward the

440
00:22:17.599 --> 00:22:21.200
<v Speaker 1>front of the cabin. Look at that reinforced locked cockpit door.

441
00:22:22.079 --> 00:22:24.240
<v Speaker 1>We put so much immense faith in the millions of

442
00:22:24.240 --> 00:22:27.519
<v Speaker 1>dollars of cutting edge technology, the complex automation, and the

443
00:22:27.559 --> 00:22:31.440
<v Speaker 1>brilliant aerospace engineer in keeping that heavy aluminum tube safely aloft.

444
00:22:32.079 --> 00:22:33.680
<v Speaker 1>But at the end of the day, when the weather

445
00:22:33.720 --> 00:22:36.799
<v Speaker 1>turns violent and the alarms start blaring, the ultimate safety

446
00:22:36.799 --> 00:22:40.400
<v Speaker 1>of that aircraft and everyone on board still hinges entirely

447
00:22:40.519 --> 00:22:44.480
<v Speaker 1>on the fragile, exhausting biological reality of the human mind,
