So this is what REALLY happened
Not the only one who has insinuated that. Howard Dean believes that too. Friggin retards...
Wrote an e-mail to the guy who wrote it, said it's funny that an economist thinks he knows more than structural engineers, and the one engineer from MIT he quotes stated they collapsed from the heat.
Here's the one major flaw in their theory:
"Eagar points out the steel in the towers could have collapsed only if heated to the point where it "lost 80 percent of its strength," or around 1,300 degrees Fahrenheit. Critics claim his theory is flawed since the fires did not appear to be intense and widespread enough to reach such high temperatures"
A simple house fire fueld by typical furnishings like couches and chairs, ect, easily reaches temps in excess of 1300 degrees at ceiling level. Flashover occurs and an entire room ignites at once, at which point temperatures exceed 1300 degrees.
Steel begins to lose it's tensile strength at 1000 degrees. While much higher temperatures are required to actually MELT it, collapse is a common occurence at these lower temps. As the steel heats and begins to lose strength, it will begin to sag or twist, which places great strain upon fasteners and other attached structural components. One of the basic rules of firefighting in buildings with exposed structural steel is that keeping water on strucural steel is almost as important as water on the fire. At the very basic level of firefighting training, we teach our newbies these FACTS. Anybody who really wants to know about fire and it's effects on a building should check out "Collapse of Burning Buildings" By Vincent Dunn, FDNY, or "Building Construction for the Fire Service" by Francis Braniggan. These dumbass conspiracy theorists could a least try to get a couple of facts in there. Timmay always used to quote guys like this, saying the Pentagon was hit by a cruise missle, etc.
