24 Replies in this Sub-ThreadOh ya, and there are over 1,300 architects and engineers who agree the buildings should not have fallen. Including the person that designed the twin towers who said a plane hitting the building would be akin to shoving a pencil through a screen door. http://www.ae911truth.org/news/41-articles/407-buildingwhat-appears-on-geraldo-at-large-on-fox-news.html

It wasn't the plane. The plane's impact actually blew off the fireproofing on the structural i-beams. The heat of burning jet fuel weakened the structure and strength of the metal. The buildings then collapsed under the weight of the higher floors. Spray-on fire insulation for metal buildings is now being cycled out in new construction because of this. Unfortunately, buildings with the old style of fire proofing cannot be replaced unless they are destroyed and rebuilt. Any other construction related insights you wish to know?
