As I understand it the heat of the fire about 2/3 of the way up the building caused a failure of the supports at this level from each corner to the central lift shaft. Once this had occurred the weight of the building above caused this level to collapse and impact on the level below. This failed on impact also and there was a progressive collapse after this. Each floor was essentially suspended from the corners - there wasnt much strength in the central shaft. If the fire had been at the top of the building the collapse probably wouldnt have happened. No matter what the motives of the govt for such a plot, I think it would be far fetched to suggest that the whole thing was engineered to justify the war. I just dont believe GB or others have the power/competence to achieve such an outcome, even if they thought of it Conspiracy theories are good fun but they have to have some credibility

Disregarding the politics entirely, a serious investigation of exactly how and why the buildings collapsed is very important forensics for those who design and build such buildings.
