Why wasn the WTC designed for the events of 9/11?
I have seen shows, listened to professors where I attended college discuss it, and talked to several structural engineers about the topic of the WTC – I majored in civil engineering and now do structural engineering for a living. Based on all that, here is my response: The “fireproofing” if you want to call it that (really a misnomer, you can’t really fireproof, or earthquake-proof, or wind-proof anything) used in the WTC was spray-on stuff applied to the steel structural members in the buildings during construction. When the planes hit the buildings, the force literally blew off the fireproofing material, leaving the steel that was not directly damaged by the plane crash susceptible to the excessive heat resulting from the burning jet fuel. That is why the steel members failed – steel loses its strength when it is heated, and the buildings subsequently collapsed.
