In fact, the official story now admits that photos were taken by a
Pentagon security camera.
The problem with the five frames of the "Pentagon security camera" record
of the Flight 77 impact is that none of them show a Boeing 757 about to
strike the Pentagon facade. The authorities claimed that the security
camera frame rate was 100 frames per second. Let us suppose the frame rate
was only 10 frames per second, and that the impact speed of Flight 77 was as
high as 780 fps or 530 mph, the figure stated by Civil Engineering Magazine,
Feb 2003. In 1/10 second, the plane would travel 78 feet. Thus, there
should exist a frame showing the nose of a 757-200 in AA colours within 78
feet of striking the Pentagon facade, i.e. within half a length of a Boeing
757-200. Given that the actual frame rate was likely to be considerably
higher, the final pre-impact frame would probably have the nose well within
25 feet of the wall. In addition, the plane was supposed to be approaching
at a 45 degree angle, so the gap from nose to wall and the slightly rotated
aircraft length are foreshortened by cos[(angle of impact from the
perpendicular) - (angle of camera slight inclination from parallel to
facade)] which makes it even easier to fit a good view of Flight 77 in the
frame.
It took six months and the release of French books about "Pentagate" before
the authorities grudgingly released the five frames of "evidence". If the
events occurred as advertised, with an AA Boeing 757 involved, video
evidence clearly showing the plane would exist and would have been made
available. By 2004, video evidence had still not been publicised. Thus,
the Pentagon incident was carried out in such a way that some witnesses
would find the official story plausible, but real-time video evidence would
disprove it. Ergo, an AA Boeing 757 did not strike the Pentagon on 9/11.
