Yeah, I saw it, it's the same crap that's been going around the net for years. He says "no 757 was recovered from the Pentagon." Well what do you expect? It hits a concrete building, do you think you're going to find it parked neatly inside? And by the way, they did find wreckage of the plane, and they found tissue remains of passengers, so he's flat out wrong on that count.
Most conspiracy theories are just silly, but there's something about this one that gets under my skin.
Oh, and read this:
