ScottBailey correct, a commercial airliner cannot descend from 7000ft in 2 and half minutes and make a tight 360 degree turn bringing it level to the ground without it breaking apart from the G-Forces, and thats before we even talk about the ability of the pilot doing it. Fortunately for those who put together the 9/11 report there are many who don’t understand those physics and therefore the original story seems plauisble. Its not plausible. Its complete nonsense.
7500ft down to ground level in 2 and a half minutes is technically a nose dive for a commercial 757, if that indeed happened (which it didnt when looking at the actual radar record) then the fuselage would break apart when levelling the nose. Even an experienced fighter pilot would struggle to do it before crashing into a fireball.
