The Perdue re-creation video shows a thin aluminum sheet skid off the top of the plane. They show that same thin flap of aluminum go through 3 re-inforced steel columns with no resistance. The Perdue video was a silly cartoon with little to no real physics.
The assertion that the Purdue study confirms the NIST and FEMA studies is inaccurate. They are actually at odds with one another
The following statement was used in the Purdue simulation: ‘The weight of the aircraft’s fuel, when ignited, acted like a flash flood of flaming liquid.’ This is a direct contradiction of the FEMA report which stated: ‘despite the huge fireballs caused by the two planes crashing into the WTC towers each with 10,000 gallons of jet fuel, the fireballs did not explode or create a shock wave that would have resulted in structural damage.’
These computer guys at Purdue are animators, and have no idea how that plane broke up inside the building or how much fuel exploded on impact instead of knocking out columns first. I wish we really knew, but this animation is just to bolster the government’s theory. It really does not explain WTC 7 where no plane hit, yet it collapsed in a similar manner. It does not explain the South Tower, where the impact of the plane was more oblique, not centered on the Core Columns. It also does not explain all the firefigher reports (over a hundred different individuals) who heard and felt explosions throughout the building. And most importantly it does not explain how the buildings could have fallen at almost freefall speed, when a gravity-driven collapse would have been much slower because of the absorption of energy required by each floor in order to snap all the bolts or rivets and welds that held the steel frame together. The scary thing is that if WTC 7 really did collapse without explosives, then no one should enter a skyscraper till we find out why, and if explosives really did bring the three buildings down but is being covered-up and not investigated, then the USA is the scariest place you can imagine
Another thing I read from the NIST report is also contradicted here: NIST admits that the only parts of the planes that could have severed or even significantly damaged the core columns were the engines and the wheel assemblies. Since one of the engines and wheel assemblies from second plane was observed to exit the building on impact, at most 4 core columns in WTC2 and 2 core columns in WTC1 could have been severed, not nearly enough to explain collapse. Certainly the NIST does not support the high numbers of core columns severed that this “scientific animation”.
This video simulation does NOT show how both complete towers could have collapsed, just how one building was impacted by one jetliner. This video suggests – without acknowledging that it does so – that such an impact could cause such a building to collapse, while providing nothing valid to support such a claim
Let's see them try to simulate how damaging part of the upper story on ONE SIDE ONLY of one of these towers could have caused the whole thing to crumble in just slightly slower than freefall speed, symmetrically, straight down through it's own structure.
What this simulation does is provide support for NIST’s simulation of the impact; it just repeats that story, but doesn’t explain how a total collapse of s steel-framed hi-rise can come about from an uneven impact and the resulting uneven damage.They seem to think that if they keep telling the same lies over and over again it will somehow turn to the truth. That’s not science, it’s called marketing and advertising.
This Purdue University “study” claims to be independent but in reality has been federally funded and was conducted by individuals with direct links to the Pentagon and the White House.
The Study was funded by the National Science Foundation (NSF). The board of the NSF was appointed by George W. Bush and confirmed by the United States Senate. Its director, Dr. Arden L. Bement Jr, has worked for the Department of defense, where he was under secretary for research and engineering, and DARPA (the Defense Advanced Research Projects Agency), which is responsible for the development of new technology for use by the military and famed for its black op projects and offshoot offices.
So while it claims to be independent the study was in fact funded by the government and carried out by long time government hired hands. The study clearly set out not to attempt to discover anything new but to prove the preconceived official fire theory.
Again this underscores the fact that a truly independent investigation into 9/11 is the only way the mountains of evidence pointing towards a controlled demolition will even be considered.
I suspect that once independent programming experts are allowed to examine the computer program which produced the present model under consideration they will discover it to be skewed to produce equally flawed theory as well.
I also recall the “scientific animation” on Nova shortly after 9/11 which demonstrated the “pancake theory”, which essentially ignored the existence of the core columns altogether, that has since been thoroughly debunked, even by the NIST. The point being that a “sciency-looking” animation proves nothing.
