Let’s not bother, at this point, with pundits who sweep in, say they couldn’t be bothered reviewing the evidence and then proceed to call anyone who questions the NIST explanation a “whack-job”.
Better to stick to the science and the verifiable facts. Here is some of the science and NIST’s reaction to it:
Here’s what happens when science confronted NIST:
… and again:
John Gross, one of the lead engineers of the NIST report is questioned about the existence of molten steel at the WTC building, the collapse of Building 7, and also explains how the NIST report did not do any analysis of the collapse of all three buildings. This video was shot on October 18, 2006. John Gross was asked to come speak at the University of Texas at Austin by the Phil. M. Ferguson Fund. A UT 9/11 Truth student organization called A Project for the New American Citizen was there to ask questions and film his response. This footage may appear in Loose Change Final Cut.
Ironically, the vast majority of those who created and promoted that propaganda probably did so innocently, never questioning the official version of events.
Academics helped to explain the collapses of the Twin Towers in articles in respected publications. Just two days after the attack, a scientific paper purported to fully explain the unprecedented engineering failures using “elastic dynamic analysis.” “Why Did the World Trade Center Collapse? – Simple Analysis” was published in the Journal of Engineering Mechanics ASCE on 9/13/01. Peer review of this paper and of other theories volunteering to explain the collapses was conspicuously absent.
Here is another commentary on the NIST Report:
The most important part of NIST’s report was a collapse model that bore no resemblance to the observed collapse. In Part 3 of NIST Finally Admits Freefall, Mr. Chandler explains the centrality of the model in NIST’s investigation: [i]
“NIST’s so-called investigation actually consists of finding a way to reproduce the mysterious collapse of the building using a computer model. The assumption is that if the computer model can be made to reproduce the observed collapse pattern, that must be how it happened…
The very process of running the model until it produces the kind of results you’re looking for is called selection bias. If you think about it, NIST’s methodology is explicitly based on selection bias. Even if you can show what might have happened, it doesn’t show what actually did happen.”
Despite adjusting its inputs to achieve the desired result, the NIST model does not come close to reproducing the observed collapse:[ii]
[ii] NIST NCSTAR 1-9A, “Global Structural Analysis of the Response of World Trade Center Building 7 to Fires and Debris Impact Damage,” Washington, DC. November 2008. p.111.http://wtc.nist.gov/NCSTAR1/NCSTAR1-9index.htm
Foreign Policy Journal adds:
A major piece of evidence in the WTC 7 collapse is the fact that WTC 7 underwent free-fall acceleration for a period of at least 2.25 seconds. A free-falling building means there is no supporting structure whatsoever below to slow the building’s fall. The NIST theory does not explain this astounding fact.
However, if their theory is to believed, the 2.25 seconds of free fall must have resulted from near-simultaneous buckling and breaking of the 58 perimeter columns and most of the 25 core columns over eight stories. The only evidence NIST provides to support their theory is in the form of a computer model.
Another requisite for a scientific theory is that the empirical data the theory is based on must be reproducible by others. Other scientists must be able to perform the exact same experiments and obtain the exact same results.
Unfortunately, NIST’s only empirical data to explain the eight story buckling, the data their computer model is based on, is unavailable to independent researchers. It is unavailable because NIST refuses to release it. NIST has stated that releasing the data “might jeopardize public safety”.
So because the NIST model cannot be verified, it is meant to be taken on faith. The NIST model, then, is faith-based, not science-based.
More on this later. NIST itself appeared to soften its stance, as of 7/5/07:
A new eyewitness inside WTC-7 on the morning of 9/11 heard explosions before either of the Twin Towers collapsed. He was summoned to the Office of Emergency Management Operating Center (OEMOC), also known as “Rudy’s Bunker,” on the 23rd floor of the building. The center had been especially prepared for the Mayor and other officials to gather in case of a terrorist attack or other emergency. Some have wondered why Giuliani did not go to the OEMOC but instead remained some distance from the World Trade Center. This witness, who testified at official hearings and whose identity will be revealed in the general-theater-release version of “Loose Change,” has information that sheds light on this and other questions about WTC-7.
In its latest press release (29 June 2007), NIST acknowledges that it is “considering whether hypothetical blast events could have played a role in initiating the collapse . . . (and) led to (WTC-7′s) structural failure” (http://www.nist.gov/public_affairs/releases/wtc_062907.html). Blast events would be consistent with a controlled demolition.
This is not reported by debunkers. It continues:
Even James Glanz, a reporter for The New York Times, admitted in an early story (29 November 2001) that the collapse of WTC-7 is even more perplexing than is the destruction of the Twin Towers, because no reinforced, steel structure high-rise building had ever collapsed due to fire in the history of structural engineering. “Indeed, no steel structure high-rise collapsed due to fire before 9/11 nor after 9/11 – nor, if our research is correct, on 9/11.”
The Committee on Science, U.S. House of Representatives, March 6, 2002 , said:
Some of the critical pieces of steel—including the suspension trusses from the top of the towers and the internal support columns—were gone before the first BPAT team member ever reached the site. Fortunately, an NSF-funded independent researcher, recognizing that valuable evidence was being destroyed, attempted to intervene with the City of New York to save the valuable artifacts, but the city was unwilling to suspend the recycling contract.”
Steel and debris from the site was sent to Fresh Kills where it was examined and sifted. As the Department of Sanitation could no longer handle the steel with their equipment, and … engineers thought the steel would destabilize the landfill, DDC received verbal permission to ship the steel to New Jersey. By the end of June 2002, over 1.6 million tons of steel and other debris were removed from the site.
“[O]n September 28, the New York Times learned that the city was recycling the steel. When the Times contacted Kenneth R. Holden, commissioner of the Department of Design and Construction, he said that no one from the investigative team had asked him to keep or inspect the steel.
The ASCE, it turned out, had faxed a request, but to the wrong fax machine. Late that afternoon, after reporters shuttled the correct fax number to the ASCE, Holden said that a request had finally reached him.”
Mayor Giuliani had been asked to halt the removal but his office did not respond to these requests. Commissioner Kenneth R. Holden … was given an award in 2002 by the AIA New York Chapter after he had overseen the criminal destruction of the steel from the World Trade Center.
In its July 2008 Draft Report for Public Comment, the National Institute of Standards and Technology (NIST) initially claimed that Building 7 collapsed 40% slower than free fall acceleration.[i]
Why would NIST want to say Building 7 did not experience free fall? NIST’s lead technical investigator, Shyam Sunder, stated in the WTC 7 technical briefing that free fall could only happen when an object “has no structural components below it.”[ii]
The only way for a building to have no structural components below it is to remove the lower structural components with an external force such as explosives. If the upper part of a building is crushing its lower structural components, in other words, doing the work of removing them, not all of its energy will be converted into motion and its descent will not be free fall.Only explosives can instantaneously remove 8 stories allowing the upper structure to accelerate downwards in free fall. The absolute free fall of Building 7 over a period of 2.25 seconds is by itself overwhelming evidence that explosives were used to bring down the building.
Barry Jennings was Deputy Director, Emergency Services Department, New York City Housing Authority. He was inside Tower 7 when the second plane had struck tower 2. He very clearly states he heard multiple explosions well before the collapse of Tower 7, and he barely made it out due to these explosions.
Here is a demolition expert on the subject [H/T Revolution Harry]:http://youtu.be/877gr6xtQIc
Another demolition expert:
“In my opinion WTC7 was with the utmost probability brought down by controlled demolition done by experts” says Hugo Bachmann, Professor emeritus for structural analysis and construction at ETH*. And also … Schneider, another Professor emeritus for structural analysis and construction at ETH, interprets the small number of existing videos as indices that “WTC7 was with the utmost probability brought down by explosives”.
Foreign Policy Journal acknowledges difficulties with CD:
There definitely are problems with the controlled demolition explosives theories. For instance, although there is some evidence of explosive sounds, in the available audio/visual evidence of the WTC 7 collapse, you don’t see the flashes and the loud booms typically seen with explosive controlled demolitions. But the sounds and flashes could be muted by Romex blasting mats, for example.
Non-typical technologies could also have been used. Recent experiments by the engineer Jonathan Cole have shown that relatively small amounts of thermate, thermite mixed with sulfur, can cut through vertical support beams like a shaped charge and yet produce much less noise. These experiments also show that thermate can also easily weaken beams and cut bolts.
Note that in typical controlled demolitions the building’s structure is weakened as much as possible to minimize the amount of high explosive needed. Explosive nano-thermite has also been found in the WTC dust.
So the inescapable and disturbing conclusion is that the most scientific theory available for the WTC 7 collapse is that it was a controlled demolition, brought down with explosives. This conclusion shows without a doubt that a thorough independent scientific investigation into the 9/11 event must be undertaken. Until now, this has not been done.
Another simple take, for good measure:
This is one of the key vids dealing with NIST’s claim that there were no explosions:
The chemical aspects:
Ignoring the Guide for Fire and Explosion Investigations put out by the National Fire Protection Association, the National Institute of Standards and Technology (NIST) did not test for evidence of explosives, because, according to NIST spokesperson Michael Newman:
“If you’re looking for something that isn’t there, you’re wasting your time… and the tax payers’ money.” [i]
NIST also claimed that no steel was recovered from Building 7. While it is true that virtually all of the steel from Building 7 was destroyed illegally, this claim is blatantly contradicted by Appendix C of the FEMA Building Performance Study, which called for further study of a piece of steel recovered from Building 7 that had experienced a “severe high temperature corrosion attack.” [ii]
The Worcester Polytechnic Institute Journal, Transformations, described this piece of steel, saying: [iii]
“A one-inch column has been reduced to half-inch thickness. Its edges–which are curled like a paper scroll–have been thinned to almost razor sharpness. Gaping holes–some larger than a silver dollar–let light shine through a formerly solid steel flange. This Swiss cheese appearance shocked all of the fire-wise professors, who expected to see distortion and bending–but not holes.”
The authors of Appendix C explained that, “the severe erosion found in several beams [in the debris field of Building 7] warranted further consideration.” [iv]
They hypothesized that a eutectic formed in the steel at approximately 1000° C due to a slow sulfidation process in the debris pile, however, independent researchers challenged this hypothesis, arguing that: [v]
“[T]o form a molten iron-oxygen-sulfur eutectic at about 1000° C would require a very high concentration of sulfur… The fact that sulfur evaporates at a low temperature, 445° C, along with the very low levels of elemental sulfur in office buildings appears to preclude the possibility that the eutectic could have formed as a result of a slow sulfidation process in the debris pile.”
The authors of Appendix C concluded by saying, “No clear explanation for the source of sulfur has been identified…A detailed study into the mechanisms of the phenomenon is needed to determine what risk, if any, is presented to existing steel structures exposed to severe and long-burning fires.”

[vii] A complete compilation of documented interviews, videos and articles:
1. NIST told porkies, either knowingly, needing to cover up their errors or else they plain didn’t know WTF they were on about.
2. From the computer models to the rummaging around in the dust to the eyewitnesses, the official reports don’t stack up.
3. If there was controlled demolition, which is overwhelmingly indicated, as you saw in the vids and the follow up quotes, then that has direct implications.
OK, let’s not draw any conclusions from that if you don’t feel like it but to what do you then ascribe THIS, which followed it?
