Implicitly acknowledges controlled demolition only means by which towers could have fallen at free fall speed

Paul Joseph Watson

The National Institute for Standards and Technology has been forced to admit that the total free-fall collapse of the twin towers cannot be explained after an exhaustive scientific study, implicitly acknowledging that controlled demolition is the only means by which the buildings could have come down.

In a recent letter (PDF link) to 9/11 victim’s family representatives Bill Doyle and Bob McIlvaine, NIST states, “We are unable to provide a full explanation of the total collapse.”

A 10,000 page scientific study only offers theories as to how the “collapse initiation” proceeded and fails to address how it was possible for part of a WTC structure to fall through the path of most resistance at freefall speed, completely violating the accepted laws of physics.

In addition, NIST’s own studies confirmed that virtually none of the steel in either tower reached temperatures hotter than 500 degrees. The point at which steel weakens is 1000 degrees and melting point is reached at 1,500 degrees, according to NIST itself.

“NIST’S 10,000-page report purports to explain what it calls “collapse initiation” — the loss of several floors’ vertical support,” writes Kevin Barrett of Scholars for 9/11 Truth. “In order to dream up this preposterous scenario, NIST had to ignore its own tests that showed that virtually none of the steel got hotter than 500 degrees f. It had to claim that somehow the planes took out many core columns, despite the fact that only a direct hit by an engine would have been likely to do so, and that the chances of this happening even once are fairly low. It had to preposterously allege that the plane that nicked the corner of the South Tower took out more core columns than the one that hit the North Tower almost dead center. It had to tweak all the parameters till they screamed bloody murder and say that the steel was far weaker than it actually was, the fire was far hotter than it actually was, the sagging was far greater than it actually was, and so on. And so NIST hallucinated a computer-generated fantasy scenario for “collapse initiation”–the failure of a few floors.”

“But how do you get from the failure of a few floors to total collapse at free-fall speed of the entire structure? The short answer: You don’t. Anyone with the slightest grasp of the laws of physics understands that even if all of the vertical supports on a few floors somehow failed catastrophically at exactly the same moment–a virtually impossible event, but one necessary to explain why the Towers would come straight down rather than toppling sideways–the top part of the building could not fall THROUGH the still-intact, highly robust lower part of the building, straight through the path of most resistance, just as fast as it would have fallen through thin air.”

“Thus total free-fall collapse, even given NIST’s ridiculous “initiation” scenario, is utterly impossible. The probability of it happening is exactly equal to the probability of the whole building suddenly falling upward and landing on the moon,” concludes Barrett.

NIST have yet to properly address the sudden freefall collapse of WTC Building 7, which imploded on the late afternoon of 9/11 despite not being hit by a jetliner.

In August 2006, NIST promised to scientifically evaluate whether explosive devices could have contributed to the 47-story building’s collapse but no answers have been forthcoming.

In August of this year, James Quintiere, Ph.D., former Chief of the Fire Science Division of the National Institute of Standards and Technology, called for an independent inquiry into NIST’s investigation of the collapse of the twin towers.

Quintiere said NIST’s conclusions were “questionable”, that they failed to follow standard scientific procedures and that their failure to address Building 7 belied the fact that the investigation was incomplete.
