The arguements on that site Gray gave are interesting: read them people, then rationally argue against them, if you would.
I find the video evidence that at least one of the planes wasn't a standard Boeing to be worrying, though inconclusive. I decline to accept their arguements that an exploding jet full of jet fuel couldn't do sufficient damage to a building like that to make it collapse until I see the calculations myself (I suspect they may have neglected the momentum of the plane, or the shock wave from the explosion). There is a lot of food for thought there though.
BTW, for those who argue that the plane's debris all entered the Pentagon, I've seen a picture of its entry hole, with an appropriately scaled plane placed in front of it - the wings would have had to have snapped off, and then been sucked in after the fuselage. Maybe that could happen - my stress and air-flow analyses aren't what they could be.
