If you click on the above link to Purdue U., when you get there click the link at the upper-left. And give it a minute for the animation to load (it's 9 MB)
FYI, these are not a bunch of Rove-Bushco-Halliburton knee-jerk neocon Nazis. These are professional engineering instructors at a highly-regarded engineering school (although they can't put a decent football team together. Sorry, had to say it. Go Blue!!) that assessed and examined every aspect of the incident.
Uh, Rosie, before you go spouting off again, you might want to look at what people who actually KNOW WHAT THEY'RE TALKING ABOUT have to say (And that goes double for your buddy Joy Behar). Unless, of course, you just want to stay ignorant. But, if you really want to know the truth--THE TRUTH--then maybe you ought to listen to the PROFESSIONALS who said:
The simulation depicts how a plane tore through several stories of the World Trade Center north tower within a half-second and found that the weight of the fuel acted like a flash flood of flaming liquid, knocking out essential structural columns within the building and removing fireproofing insulation from other support structures.But, but, but...Rosie said that fire can't melt steel!!! She said it, it has to be true!! She knows more about engineering and metallurgy than any stupid university professor!!! She is Rosie O'Donnell, you know!![...]"The crashes and computer models you often see on television are not scientifically accurate," he says. "This provides an alternative that is useful to the nonexpert but is also scientifically accurate, so it provides a more realistic picture of the event."[...]As with an earlier simulation developed by this team that examined the 9/11 attack on the Pentagon, the World Trade Center simulation showed that it was the weight of the 10,000 gallons of fuel more than anything else that caused the damage.
"It is the weight, the kinetic energy of the fuel that causes much of the damage in these events," Hoffmann says. "If it weren't for the subsequent fire, the structural damage might be almost the same if the planes had been filled with water instead of fuel."
