1
00:00:04,940 --> 00:00:02,480
this is the flight path of American

2
00:00:07,909 --> 00:00:04,950
Airlines flight 77 from where it took

3
00:00:09,830 --> 00:00:07,919
off at Washington Dulles Airport to

4
00:00:12,770 --> 00:00:09,840
where it was hijacked turned around flew

5
00:00:16,039 --> 00:00:12,780
back towards Washington and crashed into

6
00:00:17,810 --> 00:00:16,049
the Pentagon now as you can see towards

7
00:00:19,760 --> 00:00:17,820
the end of the flight path there's this

8
00:00:21,800 --> 00:00:19,770
loop and some people said this loop is

9
00:00:26,390 --> 00:00:21,810
kind of suspicious because it looks

10
00:00:28,790 --> 00:00:26,400
people think about flying in loops this

11
00:00:30,380 --> 00:00:28,800
is technically a circuit not a loop a

12
00:00:31,880 --> 00:00:30,390
loop would be vertical but let's go to

13
00:00:33,709 --> 00:00:31,890
loop for now because that's what most

14
00:00:36,410 --> 00:00:33,719
people call it it flies in this

15
00:00:38,330 --> 00:00:36,420
descending circle here so it could

16
00:00:41,060 --> 00:00:38,340
impact the Pentagon which is over here

17
00:00:44,750 --> 00:00:41,070
the reason the pilot did this is that at

18
00:00:46,490 --> 00:00:44,760
this point here presumably where he

19
00:00:48,560 --> 00:00:46,500
decides what he's going to actually fly

20
00:00:50,750 --> 00:00:48,570
into where he sees the Pentagon down

21
00:00:52,610 --> 00:00:50,760
here it's very difficult to fly down a

22
00:00:54,680 --> 00:00:52,620
plane like this at this steep of an

23
00:00:57,049 --> 00:00:54,690
angle so there wasn't enough room for

24
00:00:58,729 --> 00:00:57,059
him to nose down and go straight into

25
00:01:02,139 --> 00:00:58,739
the Pentagon from here so what he did

26
00:01:06,020 --> 00:01:02,149
was a much more gradual quite shallow

27
00:01:08,000 --> 00:01:06,030
ordinary turn to the right and what he

28
00:01:10,130 --> 00:01:08,010
would have done is he would notice what

29
00:01:13,100 --> 00:01:10,140
his heading was here it's basically due

30
00:01:15,620 --> 00:01:13,110
east and he would have just started to

31
00:01:19,010 --> 00:01:15,630
turn and just kept at a constant rate

32
00:01:20,840 --> 00:01:19,020
turn knowing that when he's gone back

33
00:01:22,310 --> 00:01:20,850
around to facing east again he would

34
00:01:24,550 --> 00:01:22,320
have been more or less back where he

35
00:01:26,990 --> 00:01:24,560
started and he doesn't really change

36
00:01:29,090 --> 00:01:27,000
what he would have actually hit if you

37
00:01:31,550 --> 00:01:29,100
look at where on the Pentagon he would

38
00:01:34,819 --> 00:01:31,560
have hit from this position is hitting

39
00:01:37,130 --> 00:01:34,829
over here from down here it would hit

40
00:01:38,569 --> 00:01:37,140
yeah pretty much the same side doesn't

41
00:01:40,969 --> 00:01:38,579
really make any difference he ends up

42
00:01:42,889 --> 00:01:40,979
missing right here and you can see the

43
00:01:45,410 --> 00:01:42,899
memorial here where the flight path is

44
00:01:46,760 --> 00:01:45,420
indicated where it hits the Pentagon so

45
00:01:53,200 --> 00:01:46,770
what I'm going to try and do is

46
00:01:56,060 --> 00:01:53,210
duplicate this in X plane flying from

47
00:01:58,940 --> 00:01:56,070
back over here somewhere

48
00:02:00,530 --> 00:01:58,950
this position here where you can't

49
00:02:02,389 --> 00:02:00,540
actually really see anything so I'm just

50
00:02:04,700 --> 00:02:02,399
going to fly from here east at about

51
00:02:07,719 --> 00:02:04,710
this height then when I get there I'll

52
00:02:10,210 --> 00:02:07,729
make this turn and I will descend in and

53
00:02:13,000 --> 00:02:10,220
and hit the Pentagon in approximately

54
00:02:16,660 --> 00:02:13,010
the same manner that was done so let's

55
00:02:21,990 --> 00:02:16,670
see what happens all right

56
00:02:24,910 --> 00:02:22,000
Here I am flying east from that position

57
00:02:27,490 --> 00:02:24,920
and I'm just gonna basically try to

58
00:02:34,870 --> 00:02:27,500
maintain this altitude of around 8,000

59
00:02:36,850 --> 00:02:34,880
feet until I get a bit closer yeah I see

60
00:02:38,410 --> 00:02:36,860
a freeway over the right I think I'm

61
00:02:42,070 --> 00:02:38,420
gonna do is try to follow that for you I

62
00:02:44,470 --> 00:02:42,080
n I think that freeway is gonna go

63
00:02:46,390 --> 00:02:44,480
towards Washington which is what I was

64
00:02:51,880 --> 00:02:46,400
so I'm just gonna turn a little bit to

65
00:02:54,370 --> 00:02:51,890
the left here although the freeway in

66
00:02:57,220 --> 00:02:54,380
fact I can see some tall buildings just

67
00:02:59,740 --> 00:02:57,230
right in the center of the screen so

68
00:03:03,490 --> 00:02:59,750
narrow I'm going roughly in the right

69
00:03:06,910 --> 00:03:03,500
direction let's increase my speed a

70
00:03:09,309 --> 00:03:06,920
little crease the throttle which will

71
00:03:12,789 --> 00:03:09,319
help maintain my altitude don't want to

72
00:03:16,059 --> 00:03:12,799
get too fast if I get over around 350 it

73
00:03:17,620 --> 00:03:16,069
makes it difficult to make maneuvers I'm

74
00:03:23,400 --> 00:03:17,630
not flying in a perfectly straight line

75
00:03:31,660 --> 00:03:28,840
okay so I'm going towards these tall

76
00:03:42,590 --> 00:03:31,670
buildings not entirely sure where the

77
00:03:49,940 --> 00:03:44,680
you already can't see very much up here

78
00:03:51,170 --> 00:03:49,950
from this distance got nothing to stop

79
00:03:52,390 --> 00:03:51,180
you to have me some binoculars or

80
00:03:54,110 --> 00:03:52,400
something or looking ahead

81
00:03:56,630 --> 00:03:54,120
and of course there would be more than

82
00:04:00,380 --> 00:03:56,640
one person in the cabin which would be

83
00:04:02,870 --> 00:04:00,390
helpful I said I'm not sure about that

84
00:04:15,719 --> 00:04:02,880
hard to check that so anyway heading

85
00:04:22,510 --> 00:04:18,699
can we see the Pentagon I can't we see

86
00:04:32,429 --> 00:04:22,520
to any of the buildings Washington I

87
00:04:40,829 --> 00:04:36,899
oh I see the Pentagon I'm gonna turn

88
00:04:42,839 --> 00:04:40,839
towards the Pentagon alright so now what

89
00:04:45,379 --> 00:04:42,849
I'm gonna do is assume I am too high I'm

90
00:04:47,699 --> 00:04:45,389
gonna reduce the throttle down to zero

91
00:04:49,699 --> 00:04:47,709
see there's pentagon straight ahead

92
00:05:01,049 --> 00:04:49,709
there now what I'm going to do is do a

93
00:05:03,479 --> 00:05:01,059
fixed-rate turn of a two minute oops I

94
00:05:08,939 --> 00:05:03,489
get the turn indicator which is just

95
00:05:10,829 --> 00:05:08,949
above me here on the second pip said

96
00:05:14,519 --> 00:05:10,839
throttle to zero and I'm just going to

97
00:05:18,979 --> 00:05:14,529
turn until I'm facing east again so I'm

98
00:05:23,879 --> 00:05:18,989
turning around now let's say 140 degrees

99
00:05:26,989 --> 00:05:23,889
I'm descending throttles at zero so I'm

100
00:05:30,869 --> 00:05:26,999
just gonna be sinking through the air

101
00:05:35,459 --> 00:05:30,879
using my forward velocity and my height

102
00:05:37,109 --> 00:05:35,469
still maintain speed dropping down fifty

103
00:05:40,589 --> 00:05:37,119
three hundred feet just fifty two

104
00:05:42,389 --> 00:05:40,599
hundred feet and I try to keep my turn

105
00:05:45,839 --> 00:05:42,399
rate constant which means I will go in a

106
00:05:48,299 --> 00:05:45,849
circle it's not very hard you know I

107
00:05:51,869 --> 00:05:48,309
just turned the the yoke to the right

108
00:05:54,269 --> 00:05:51,879
and look at my turn right indicator make

109
00:06:00,049 --> 00:05:54,279
sure it's on the second mark there we

110
00:06:09,239 --> 00:06:06,899
and it's quite a slow procedure yeah the

111
00:06:10,619 --> 00:06:09,249
hijacker may well have to a little bit

112
00:06:14,309 --> 00:06:10,629
faster than this but I'm just gonna do

113
00:06:17,459 --> 00:06:14,319
this cuz this is what you would be

114
00:06:19,519 --> 00:06:17,469
trained to do you don't want to go too

115
00:06:21,149 --> 00:06:19,529
fast you don't want to mess things up

116
00:06:23,809 --> 00:06:21,159
it's not going to make much difference

117
00:06:28,299 --> 00:06:23,819
if you do a two minute turn or a

118
00:06:33,999 --> 00:06:30,609
you see I came around to the freeway cam

119
00:06:40,989 --> 00:06:34,009
240 degrees so it's kind of facing west

120
00:06:45,479 --> 00:06:40,999
now turning around towards the north at

121
00:06:47,409 --> 00:06:45,489
270 degrees yep turning a bit too fast

122
00:06:54,699 --> 00:06:47,419
don't want the wings to fall off the

123
00:06:57,999 --> 00:06:54,709
plane okay 220 degrees my problem when

124
00:06:58,989 --> 00:06:58,009
flying was always shaking everything

125
00:07:00,279 --> 00:06:58,999
he's supposed to check all the

126
00:07:01,749 --> 00:07:00,289
instruments and sequence to make sure

127
00:07:04,839 --> 00:07:01,759
everything's there so you know check the

128
00:07:06,399 --> 00:07:04,849
heading indicator the altitude the turn

129
00:07:13,179 --> 00:07:06,409
rate indicator the vertical speed

130
00:07:15,699 --> 00:07:13,189
indicator your your speed indicator all

131
00:07:17,789 --> 00:07:15,709
right I'm at now 330 degrees so coming

132
00:07:21,459 --> 00:07:17,799
around towards North so coming back

133
00:07:23,439 --> 00:07:21,469
around towards we shouldn't go fast

134
00:07:27,369 --> 00:07:23,449
enough otherwise I'll end up too far to

135
00:07:30,819 --> 00:07:27,379
the north can we rent facing north so

136
00:07:33,759 --> 00:07:30,829
soon I will be able to see the Pentagon

137
00:07:38,589 --> 00:07:33,769
again I'll get a visual light and you

138
00:07:39,969 --> 00:07:38,599
see I've dropped down and I think I can

139
00:07:43,419 --> 00:07:39,979
stick the notes down a bit here because

140
00:07:48,279 --> 00:07:43,429
I'm losing air speed another of my

141
00:07:54,040 --> 00:07:48,289
problems gonna fly try to get back to

142
00:07:59,410 --> 00:07:56,780
when you get into a thousand feet level

143
00:08:03,410 --> 00:07:59,420
that means you get pretty much you're

144
00:08:07,130 --> 00:08:03,420
close to the ground okay so coming back

145
00:08:13,540 --> 00:08:07,140
around to the east and we see all the

146
00:08:17,660 --> 00:08:13,550
buildings again you have to start

147
00:08:20,140 --> 00:08:17,670
remember where the Pentagon was just the

148
00:08:26,950 --> 00:08:20,150
end of this freeway so I'm gonna

149
00:08:31,850 --> 00:08:26,960
straighten out aim towards Pentagon

150
00:08:33,200 --> 00:08:31,860
getting some warnings now all right you

151
00:08:37,190 --> 00:08:33,210
can see the Washington Monument just

152
00:08:44,209 --> 00:08:37,200
there left to Center there and going to

153
00:08:50,780 --> 00:08:48,410
they want to drop too much speed just

154
00:08:52,850 --> 00:08:50,790
push the nose down goes increasing their

155
00:09:00,600 --> 00:08:52,860
speed tends to make the nose want to

156
00:09:06,059 --> 00:09:02,729
all right I'm very fast now so I need to

157
00:09:08,460 --> 00:09:06,069
avoid making any sudden movements I'm

158
00:09:11,989 --> 00:09:08,470
gonna I also want to get down low enough

159
00:09:15,869 --> 00:09:11,999
so I hit it getting an over speed

160
00:09:17,729 --> 00:09:15,879
indicator yeah apparently I have the

161
00:09:24,150 --> 00:09:17,739
landing gear down don't know how that

162
00:09:27,780 --> 00:09:24,160
happened I'm probably going to break the

163
00:09:36,359 --> 00:09:27,790
plane up if I keep this up okay going a

164
00:09:40,139 --> 00:09:36,369
little high and bam all right so let me

165
00:09:44,220 --> 00:09:40,149
juggle the recording mode and back out

166
00:09:46,919 --> 00:09:44,230
again see you know the problem with

167
00:09:51,389 --> 00:09:46,929
explain is it keeps the smoke which is

168
00:09:59,129 --> 00:09:51,399
very annoying let me do a different view

169
00:10:06,150 --> 00:09:59,139
here and play this so full speed back

170
00:10:11,309 --> 00:10:06,160
hello let's back out a bit and then fly

171
00:10:14,789 --> 00:10:11,319
back in again the smoke should have

172
00:10:17,069 --> 00:10:14,799
cleared you can see this smoking here

173
00:10:18,929 --> 00:10:17,079
because the engine has exceeded its

174
00:10:21,960 --> 00:10:18,939
structural limits so actually showing

175
00:10:23,340 --> 00:10:21,970
this some damage because I'm flying in a

176
00:10:36,350 --> 00:10:23,350
straight line I didn't actually lose

177
00:10:43,679 --> 00:10:40,049
not actually that hard coming in at a

178
00:10:46,169 --> 00:10:43,689
steeper angle here but it wouldn't be

179
00:10:50,460 --> 00:10:46,179
that hard to come in until a less steep

180
00:10:55,139 --> 00:10:50,470
angle shift to anterior view here I was

181
00:10:57,539 --> 00:10:55,149
going at 413 knots which isn't too far

182
00:11:00,049 --> 00:10:57,549
off what the actual plane was doing I

183
00:11:02,069 --> 00:11:00,059
think it was four hundred and something

184
00:11:04,619 --> 00:11:02,079
finally something we can do is have a

185
00:11:07,350 --> 00:11:04,629
look at the map of the route which was

186
00:11:09,689 --> 00:11:07,360
recorded in explain and here's the

187
00:11:11,669 --> 00:11:09,699
Potomac here here is my flight in and

188
00:11:13,199 --> 00:11:11,679
here is the turn I made you can see I

189
00:11:13,510 --> 00:11:13,209
did a little bit of a tighter turn it

190
00:11:15,160 --> 00:11:13,520
was

191
00:11:18,940 --> 00:11:15,170
a perfect circle but it's more or less

192
00:11:22,120 --> 00:11:18,950
the same scale as the actual flight 77

193
00:11:24,280 --> 00:11:22,130
turning path and the result was more or

194
00:11:26,410 --> 00:11:24,290
less the same so here's the actual

195
00:11:29,560 --> 00:11:26,420
flight path in Google Earth and here's

196
00:11:30,880 --> 00:11:29,570
my flight path overlay to scale you can

197
00:11:33,010 --> 00:11:30,890
see the more or less the same type of
