Ok... here we go...
the plane impacted at roughly 450 mph, that is 660 feet per second, the video showing the impacts is 30 fps (29.97 for NTSC) so the plane travels roughly 22 feet per frame. NTSC uses 484 of the 525 scan lines for video, however to save on bandwidth they are interlaces, only half displaying at a time. It is shot at a 4:3 ratio giving us approximately 640x480 ‘pixels’ to work with. At best, the closest video of the impacts was shot at over 3000 feet away and at worst several miles away. We know the tower is about 207 feet wise. The best footage I can find of the impact has the tower taking up half of the horizontal space, 320 pixels; this means that each pixel is representing 2/3rds of a foot. You simply cannot see enough details from any of the videos’ of the impacts to see anything except the plane sliding into the building. We are not talking about watching something a car hit a brick wall across the street; we are talking about watching something from several thousand feet away. It is simply impossible to see any more then that.
