What Struck The Pentagon on 9/11?

Two clips, one zoomed & reversed.
We at AN suspect this footage may have been taken from the Doomsday Plane spotted, filmed & photographed over the site on the day, but whose presence is ignored, denied or obfuscated by the authorities. Also, over 80 camera's overlooked the Pentagon, none of that footage & no images have ever emerged, why?
