Nick, you're full of shit, my friend. You are right about ONE thing, however. It wasn't a Boeing 747 that hit the Pentagon, it was a 757 - a somewhat smaller aircraft. You need to understand that these places are made of ALUMINUM. When they hit a steel and concrete structure at 500 MPH, they essentially burst into little shreds. You're not going to see wing impressions, like you did with the Twin Towers (which were open-framed steel structures clad with glass, very different from the much more solid steel-reinforced concrete walls of the Pentagon). In the Pentagon impact, the wings essentially sheared off and were shredded with the rest of the plane, merely contributing to the widening of the hole.

The main problem with this, and nearly every ridiculous conspiracy theory out there is the fact that in order for it to work, one would need thousands or tens of thousands of people to keep quiet and cooperate. This just isn't going to happen. There are plenty of people who value truth above all, and would make sure the truth was known, consequences be damned. Especially with such a massive and traumatic event as this. The fact that there is ZERO credible evidence to support your theory speaks volumes to me.

Knock off the needlessly abusive attitude. You can argue with someone without the gratuitous name calling. If you can't be reasonably civil, we don't need you here.
