Re: Interesting Video of the Crash into the Pentag [ QUOTE ]
It leveled a five story steel, concrete, and stone building, not bad for a mass of aluminium that is mostly empty space.
Also the pentagon is composed of rings, all the energy was wasted on the first outer ring. Not much made it into the second ring except the engines.
Rember, the crashes didn't bring down the WTC towers, it was the fire that melted the steel framwork.

On top of that, in what was perhaps the only good thing that happened on that day, the plane crashed into the wing of the Pentagon that had been reinforced against terrorist attacks. So it went into the part of the Pentagon that had the hardened concrete, shatter proof glass, and all the other hardening that had been done. |
