It isn't a building DW, the wings and tail are gone at impact, the fuselage get's shredded.
I am still stuck on the dimensions of the plane. There is no way that it could have made the hole it did.
remember the WTC towers were Aluminum skinned, their outer skin was their load bearing support,
the Pentagon is masonry over 3 feet of reinforced and hardened Concrete, that plane aint making it past the outer 2 rings.
it couldn't have been a missile strike, considering that building was built to withstand a direct hit by Nuclear weapons, anything less than a daisycutter wouldn't have done that much damage, a daisycutter is a very distinct looking weapon.
and loud as all hell it would've broken windows 3 miles away. the plane became a Kinetic energy weapon, a giant armor piercing bullit. only the fuselage wouldve made a hole at that speed and in that kind of building. a plane hit, who was operating it? who knows.
