1. Where are the wings? In tiny peices. To the left and right of the main hole,
you CAN see damage to the building. The freakin idiot SHOWS the damage in the picture, and denies it's there! The difference between this building, and the WTC is that the Pentagon is built like a brick sh!t house. It's TONS of concrete and steel poured into columns and blocks. The plane and wings hit the building at some 400+ MPH and simply disentigrated. The building is MUCH denser (a lot like the author of this page) than the WTC. Light aluminum hitting densly poured concrete. You physics gurus do the freakin math here. The bulk of the plane DID penetrate the lower floors of the building, but only the first ring.
Remember folks. If you fly a plane into a brick wall that is three feet thick, there well be VERY little left of the plane larger than a couple cubic inches. There are tests with fighter jets done like this on video for f'cks sake. This portion of the Pentigon had just been refurbished. Part of that was adding additional thickness to the walls to shield from attacks.
2. Why gravel? Have you ever BEEN to a large construction site with large tracked vehicles? They turn a lawn into a woman's mud westling rink with five foot deep ruts in no time.
This guy is an idiot.
