Does the hole in the photograph you provided not look remotely like a plane fuselage shape?
Oh please don't tell me actually think a plane is supposed to have fit through that hole. That's the hole that the plane's landing gear punched in the C-ring of the Pentagon. The body of the plane disintegrated on impact, which makes sense because it's mosly aluminium. But there are some parts of an aeroplane that aren't made of soft metals, and these parts don't just stop when the aluminim fuselage breaks up or when they hit a wall.
