How can the entire interior of the building just disintegrate ..

How can the entire interior of the building just disintegrate with fire. And yet leave the outside intact. ... This is just crazy talk.

I dont even need a 1st Class BSc Degree in Engineering with Honours (which I have), to see that the idea that the whole interior of the building can rotate or buckle all at once.

And the sadder truth is, then in tens of thousands of recorded building fires, some much much worse than this (Google China State TV Building Fire) this has never happened. ... Why ... Well because what you say is not possible. Failure, in all products, buildings, and indeed any structure, micro or macro always, and I repeat always has a fracture or weak point, and then the failure mode dissipates from that point throughout the structure.

And as for WTC 1 and 2. The upper floors do not have enough energy to destroy the lower. Thats simple.

Even if the upper floors could fall one full story. The resultant pulverisation, of the upper floors impacting on the lower, would in any case, quickly arrest the disintegration of lower floors. You would need energy in, in addition to (g) for the upper 1/8th of the building to destroy the lower. Where did this energy come from?
