Even though this thread's about the Pentagon, I've heard similar theories about the Towers. Yes, a plane did crash into them, there's no doubt about that. The theory here regards how they fell down. It's been rumored that there were explosives planted inside the buildings, and they were detonated after the planes crashed, to make it look like the planes took 'em down. Not saying I believe this, but that might explain why that smaller bulding fell down like a block away. But then again, I wasn't there, so I have no definate opinions on this.
