Interestingly, there is neither video footage nor any photographic evidence in the public domain showing a jetliner approaching or crashing into the Pentagon. As of May, 2006, the only video footage of the crash that has been released are clips from two Pentagon security cameras north of the crash site.
The Pentagon claims to have supplied all of the footage it has of the attack. Although the number and positions of security cameras monitoring the Pentagon is not public knowledge, it seems unlikely that only two security cameras captured the attack. Also, the Pentagon has seized footage not belonging to the military but to private businesses in the immediate aftermath of the attack.
