[FractalTheorem]

The twin towers could not have been brought down by pre-planted explosives. Look at the video. Where in the building was the start of the structural failure? Indeed, it started on the floors that were hit by the planes! Go figure!

Had pre-planted explosives been placed in these locations, then the pilots of the planes would have had to hit those exact locations on each tower, a very difficult task.

The fact of the matter is that sufficient damage occurred to the support beams of the buildings by the impact of the planes that even a lower temperature fire could sufficiently weaken the steel enough to finish it off, as the steel beams were required to support far more than their standard load.

Any other conclusion is ludicrous.
