9/11 Truth Alert - Computer Simulation Shows WTC Collapsed From Controlled Demolition

Oh wait, No it doesn't. Computer simulation shows hijacked planes crashed through the twin towers, stripping fireproofing materials from the steel columns and eventually leading to their collapse.

JUST LIKE EVERY NORMAL PERSON IN THE WORLD THOUGHT!

The 3-D animation, part of a Purdue study that took 2½ half years to complete, could help engineers design safer buildings, researchers said.

"When the developers of the World Trade Center first designed the complex, they did take into account of an accidental plane crash," said Christoph Hoffman, one of the study's lead researchers. "The only thing they didn't anticipate is the fire. If the crash impacts the water line, then a fire can burn for a long time."

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 simulation also found that the airplane's metal skin peeled away shortly after impact and shows how the titanium jet engine shafts flew through the building like bullets.

Ayhan Irfanoglu, a Purdue professor of civil engineering, said half of the building's weight-bearing columns were concentrated at the cores of the towers.

"When that part is wiped out, the structure comes down," Irfanoglu said. "We design structures with some extra capacity to cover some uncertainties, but we never anticipate such heavy demand coming from an aircraft impact. If the columns were distributed, maybe, the fire could not take them out so easily."
