A computer simulation of the 2001 World Trade Center attacks supports a federal agency’s findings that the initial impact from the hijacked airplanes stripped away crucial fireproofing material and that the weakened towers collapsed under their own weight.
The two-year Purdue University study, funded in part by the National Science Foundation, was the first to use 3-D animation to provide visual context to the attacks, said Christoph Hoffmann, a professor of computer science and one of the lead researchers on the project.
“One thing it does point out… is the absolute essential nature of fireproofing steel structures,” Hoffmann told The Associated Press. “This is something that wasn’t done originally in the World Trade Center when it was built. It wasn’t code at that time.”
Mete Sozen, a professor of structural engineering and a lead investigator on the simulation, said Purdue researchers hope their work leads to better structural design and building codes to prevent similar collapses.
“In the unfortunate development that we shall have to design structures to survive such events, the methods we have developed and will be developing will be of great use to designers,” Sozen said.
The animation, intended in part to help engineers design safer buildings, begins with a map of lower Manhattan as it appeared on Sept. 11, 2001. The video then shows a plane slicing through several stories of the World Trade Center’s north tower and follows the disintegrating plane through the interior and out the opposite side.
The report concludes that the weight of the aircraft’s fuel, when ignited, produced “a flash flood of flaming liquid” that knocked out a number of structural columns within the building and removed the fireproofing insulation from other support structures, Hoffmann said.

The real cost of environMENTALism
Wasn’t there another building called number seven which collapsed a couple hours after the two towers imploded?
Yeah sure. Computers lie and liars compute.
I seriously doubt that flying a jumbo jet into a building will ever be tried again in America.
That's a good defense if you expect people to fly fuel-laden planes into buildings regularly. What would be more effective would be to prevent planes from flying into buildings. Had most public-educated people not been repeatedly been taught to be cowards, I doubt that even one plane would have reached its destination.
The towers did not implode they collapsed - yes, we need to be sure that the media doesn’t RE-DO the verbal portion of history. If the word imploded gets into the books, then those nutcase wackos go off on how it was a plot by the Bush administration so they could go to war and attack Iraq!
Collapsed in on itself hence the word implosion.
I always wondered if these “people” realize that fuel mixing with plastics (Very common thing in office spaces) creates something called napalm. The problem with computer models is that they are only as smart and creative as the people putting them together.
#7 came down about seven hours later, not two.
Oh yeah, and it pretty much burned all afternoon before it collapsed.
This is the building that the conspiracy theorists think is the KEY to the whole diabolical plan, can’t believe you’re only now catching up. :D
Unless the Jihadists are still not satisfied with their results from the last attack on CONUS [dumb answer rant off]
Every conceivable barn door has been closed on that vanished horse. Sealed cockpits, and passengers who will clobber any errant fellow traveler in a New York minute. Plus (for show) airport security out the wazoo. Next thing will probably be chemical/dirty bomb or a nuke.
I had already used the word collapsed in the sentence and I tried to use a similar word. I should have used a thesaurus. I had some nuts at Dealey Plaza tell me it was Bush’s fault and they mentioned the other building. I was hoping for a good rebuttal next time I’m down there.
Congrats! You sire are teh winnar of the internets!
