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.
How would water put out fires on those tall towers?
