For some reason sites like this really annoy me. I didn't even read much, but I found this interesting...

But, as will be shown later, the Twin Towers did not collapse because of the plane impacts and the fires. The most likely explanation is that explosives were placed besides their structural supports at numerous levels in the towers, explosives which were detonated 56 and 104 minutes after the planes hit, bringing the towers down in controlled implosions, killing several thousand American citizens and others.

Funny though that you see the buildings starting to fall from the top to bottom, due to the massive hole in the side and lack of support for the upper floors. If there were explosives at the bottom, wouldn't the building start to collapse from the bottom upwards?
