Hmm I don't know. I mean it was pretty convincing; but I'm always really misbelieving of these conspiracy things. The Moon landing hoax was the one that really showed me that most conspiracy theories are just shite. But; I have read about this Pentagon theory before; I think it was in a Gore Vidal book (Dreaming War I think). He talks about how the precision of the approach of the plane to the Pentagon was very very very accurate. Like how its wings clipped the telphone cables across the street; and that supports the theory that the pilots were VERY well trained; eg military pilots. But; I dont know. I'm what my mother calls a Doubting Thomas. I'd need alot more evidence.
