My former company owned the twenty something story hotel that also was destroyed by falling debris that caught their building on fire. I find that this conspiracy theory about controlled demolition seems to be promoted by people with little or no knowledge of structural engineering. The main reason why these structures collapsed was the engineers never foresaw that there would be multiple structural fires all at the same time. There was not enough water in the main lines to provide for fire suppression in two 100 story buildings. Then a third, fourth, fifth and sixth building all caught on fire. There just was not enough water available to put out all the fires.

Thank you for inserting more sense into this.

This fact about the lack of water was reported many times.
The FDNY said that IF only one building had been hit that they most likely would have been able to put the fire out or at least keep it contained to the one building.
That the internal sprinkler system would have suppressed the fire enough for the fire department to eventually put it out. That does not mean that there would not have still been hundreds of deaths if not thousands. Especially of the people in the upper floors above the fire. People also forget that they blew up a truck bomb in the basement parking garage once before. That it blew out several of the structural columns yet the building did NOT collapse. However, that fire did not contain thousands of gallons of jet fuel. It also happened in the parking garage where the only other items to catch fire were the automobiles. On the upper floors there is a lot more fuel for the fire to consume.
