If it were burning and it burned all the way down to the support beams the of course its going to collapse...Now Im not saying that Bush didnt have anything to do with it..Or the man who owned the WTC but still...My theory is Bush(senior and r.) wanted the oil so they intentionally picked on the middle east knowing it would cause an attack and an excuse for a war where they can take the oil....And the man who owned the towers..all for insurance money..all I got to say
