The following three pictures were extracted from the video shown on the CNN site, allegedly originated from the Department of Defense (DOD), and were purportedly captured by the Pentagon's parking lot security camera on September 11, 2001.

Frame 1 Frame 2 Frame 3

The authenticity of the video images has never been denied by the authorities. It is possible to infer that the camera moved on image 2, or perhaps "bounced on it's support". In the upper-left and upper-right corners of the images are some fuzzy details, probably located on the glass of the booth that housed the camera. This move corresponds to the arrival at the camera's location of the shockwave transmitted by the ground, which obviously propagates much faster than the shockwave transmitted by the air. The images have probably been cropped with an image processing software, in order to let them be viewed in an animation without being disturbed by the cameraís movement (see the legend cropped on the lower left part of image 2).

A point deserves to be underscored here : it relates to the time codes on the lower part of these photos. In my opinion, they were added by a computer when saving the images on a hard disk. The fractional part of these time codes change at the system clock frequency (50 or 60 hz). I'm quite sure that they are not related to the time at which the photos were shot. Thatís because security cameras never operate at a rate between 50 and 100 frames per second. There would also never be two images with the same time code. This is confirmed by the complete pictures (read below) which don't have any time codes attached. Moreover, the comments like "impact" are put with the same typography than the time-codes, which proves that they have been put when the images have been analysed and not when they have been shot, unless - just a joke - the Pentagon has sophisticated artificial intelligence based device on it's parking's cctvs able to correctly analyse as a plane's impact what is - least to say - unclear for human analysts.

Complete pictures

I recently found on Mineapolis / St Paul web site the uncropped photos, apparently originating from the Associated Press and published on March 7, 2002. It is obvious from these frames that the camera bounces on it's support on image 2. There are two brown triangles in the upper left and upper right corners of this frame, which I believe are made of adhesive tape stuck against the interior of the booth's glass in order to protect the cameras' lens from the sunlight. These brown triangles could be the visible parts of a half-circle shaped protective piece, which is used to protect a lens during the day : the midline between these two triangles is facing south. On other frames, these triangles are hardly visible, but on image 2, the camera bouncing upwards shows this protective cover. This is however not an object which flies over the heliport of the pentagon at this precise time, as some imagined, but just a simple and clever job of the Pentagon guards to allow a camera facing south to operate all day long !

The camera location

The camera location can be seen on the following image (bottom right). Some interesting places have been indexed (in yellow). The presumed plane trajectory has been plotted in purple.

The images


The general impression, at first glance, is that something very fast is happening, and has been partially captured by the camera.

first frame
Frame 1

Just above the yellow cabinet (likely housing of the ID card reader) we can see a black mass, which suggests the tail of the airplane. At the right of the cabinet, a white smoke cloud can be seen, which could be a vortex created by the plane and/or smoke from its engines.
Note the "free" space between the left of the yellow cabinet and the front of the Pentagon. The plane must go through this space from the position on frame 1 (partially hidden by the yellow cabinet) to arrive at its supposed position inside the Pentagon after the crash. A further analysis will show that this space is around 70 m long.

second frame
Frame 2

The supposed tail of the plane has disappeared. The explosion blast comes out from the Pentagonís facade. The white color, as explained by Pierre Henri Bunel, a French explosives expert, indicates the presence of a very fast moving explosion fireball, caused by a solid explosive and not the burning of kerosene. Compared with the orange/black explosion cloud produced by the planes on the wtc towers, or with this image of a crash test by the NASA, this explosion appears much different.
Note also that the white track (vortex or engine smoke) extends now to the left up to the point where it disappears within the explosion. If the plane caused the vortex, the plane must have passed through the open space seen in the image.

third frame
Frame 3

The explosion blast extends. The white color has been replaced now by a nice red, a sign of very hot expanding gasses.
Note also that the white track has quite disappeared on the right of the yellow cabinet, which seems to prove that it was a vortex rather than smoke from an engine. The extension of the explosion, from the previous frame, could be estimated between 20 and 30 meters, by reference to the Pentagon height (24 m). Divided by sound propagation speed in air (300 m/s), this gives a delay beetween 66 ms and 100 ms. This would give frame rates of, respectively 15 and 10 frames / second : a rate lower than standard video cameras (25 or 30 frames / second), but classical for surveillance cctv cameras which often operate at these slower rates.
