in the history of the world, no highrise steel buildings have ever collapsed from fire except the 3 Silverstien buildings on 9/11/01
in 1991 8 floors in the middle of the highrise Meridian building in Philadelphia burned for 20 hours! according to the official fire report " beams and grinders sagged and twisted--some as much as 3ft--under severe fire exposures. Despite this extraordinary exposure, the colums continued to support their loads without obvious damage" and stood for many years later
Sorry, Again. You are wrong,
The Twin Towers were not steel frame buildings. That is the point and that is how you were lied to,
The point is, these building had a unique untried strudture for that height. They were concrete panel TUBE BUILDINGS.
That is why all this mis-direction is senseless,
In steel frame, this would not have happened. THAT IS THE POINT. The floors were set up as pushers against the outside concrete panel square tube, When they sagged from the heat, began by the fuel and increased by body fat and everything else, they stopping pushing the walls out. The floors above began to give way. When they loaded the first intact bottom floor enough, the concrete pillars at the corners exploded, and the entire top structure was in free fall with nothing under really but already collapsing building and a big dust cloud to block our view.
A steel frame is a set of welded and riveted, heavy I-beams. It can only be a certain height, no more. Too heavy.
They could not build the Twin Towers with steel frame, That is the point.
And the guy that built it lied for $$$ about withstanding an airplane strike. Besides, a 707 is not a 757. And the idea that steel can not sag under load when heated, is enormously dense and uninformed.
You are wrong to listen to this garbage in the first place. No Tube building had every been crashed by an airliner. So, you ignore facts and call it something else, a steel frame building,
THEY WERE NOT.
You fear the lose of control. It is more comfortable to think we did it than jihad wants our women in Burkka and us men dead in a ditch. Too scary. And we would have to fight back, which WE did. You don't like it. So you follow a fairy tale of all powerful USA.
