Scientists and Engineers Simulate Jet Colliding with World Trade Center

This looks to be interesting! Thought I'd post a link right quick. :hi:


"The researchers are analyzing how many columns were destroyed initially in the building's core, a spine of 47 heavy steel I-beams extending through the center of the structure, Sozen said."

"Santiago Pujol, an assistant professor of civil engineering, worked with the researchers to develop experimental data to test the accuracy of the simulation by using an "impact simulator" to shoot 8-ounce beverage cans at high velocity at steel and concrete targets at Purdue's Bowen Laboratory. These data enabled the researchers to fine tune and validate the theoretical model for the simulation."

Popular Mechanics quotes Mete Sozen, a professor of structural engineering at Purdue University as shrugging aside the nagging conspiracy that a Boeing 757 did not hit the Pentagon, ". . .one wing hit the ground; the other was sheared off by the force of the impact with the Pentagon's load-bearing columns," Sozen said. "What was left of the plane flowed into the structure in a state closer to a liquid than a solid mass."

Summary

The main burden of this article has been to demonstrate that the debris found outside the Pentagon is inconsistent with the impact of a Boeing 757 or any aircraft of comparable dimensions. In particular, in the absence of some agency (possibly unknown to physical science) that removed the wings, there is no way to avoid the conclusion that the wings (and therefore the aircraft) were never present in the first place. In this case, no Boeing 757 struck the Pentagon building on the morning of September 11, 2001.

We have also presented a scenario that may be much closer to the truth of what happened on the morning in question, but our main conclusion is reached quite independently of the scenario and neither implies it, nor is implied by it.

Note

We are aware of another study of the Pentagon crash by scientists at Purdue University. (Sozen 2002) One of us (Dewdney) has designed scientific simulation programs and has taught the subject for many years. A simulation program invariably involves a model of the phenomenon being simulated and the simulation is never better than the model. The Purdue simulation modeled the wings of the 757 as essentially kerosene-filled aluminum bags, in essence, with little structural strength. The wings break into sections when the plane strikes the building, each section passing between columns and spewing fuel into the growing conflagration. The rudder and tailplane pass into the building unscathed, as well.

The main problems with this model is the complete failure to take into account the structural integrity of the wing as well as the fact that fuel is stored only in tanks in the wing root, adjacent to the fuselage. As for the tail section being completely undamaged, no comment is necessary.
