It is needed in this disscussion where it seems everyone else hates America and Bush, and already knew that it was a set up. I didnt say the theory states a plane didnt hit the building. They claim its impossible for a building to collapse with fire. I was saying that the structural integrity of the building would be much weaker allowing it to be collapsed by the fire. In my opinon the explosion theory is very very unlikely.
Where would these explosives be placed? At the base of the building? That would make sense but it asks the question how would you be able to get that much explosive into a building like that, set it up and arm it without anyone noticing?
