The NIST investigation, having posted its Final Report with its absurd Building 7 joint-breaking-thermal-expansion theory in late 2008 and FAQ by Christmas, closed its doors before the independent researchers published their findings of active aluminothermic materials in WTC dust in a mainstream scientific journal; but not before they publicized findings of aluminothermic residues in the same dust samples; and not before they extracted from NIST a series of public statements, in press conferences and in written responses to requests for correction (RFCs), about the conduct of their inquiry into the cause of the skyscrapers' total destruction.
ABEL: ... what about that letter where NIST said it didn't look for evidence of explosives?
NEWMAN: Right, because there was no evidence of that.
ABEL: But how can you know there's no evidence if you don't look for it first?
NEWMAN: If you're looking for something that isn't there, you're wasting your time....
--Conversation between a reporter and a NIST spokesperson. source
As a result, NIST spokespersons are on the record saying they did not test for pyrotechnics, and offering rationales for failing to perform such tests. Those rationale -- or rationalizations -- summarized toward the end of this essay, include the assertion that testing for pyrotechnics "would not necessarily have been conclusive". That is partially true: failing to find pyrotechnic residues wouldn't rule out demolition, since demolition might have been implemented using an untraceable fuel such as hydrogen gas. But finding abundant and distributed pyrotechnic explosive residues would conclusively favor demolition -- particularly given the persuasive deductive arguments showing that the features of the buildings' destruction are incompatable with a purely gravity-driven collapse
Following his talk on NIST's then-ongoing investigation, speaker John Gross was questioned about the reports of molten metal. In the following exchange, Gross pleads ignorance of the reports.
QUESTIONER: I'm curious about, um, the pool of molten steel, that was found in the bottom of the towers.
GROSS: Please tell me about it. Have you seen it?
QUESTIONER: Not personally, but eyewitnesses there found huge pools of molten steel beneath the towers, and ah, scientists, some scientists don't think that the collapse of the buildings could have melted all that steel, and a physics professor analyzed some of that steel, Steven Jones, and he found evidence of, a, thermate residues which would have explained how the buildings collapsed by means of pre-planted explosives. So, have you analyzed the steel for those residues?
GROSS: First of all, let's go back to your basic premise that there was, ah, a pool of molten steel. I know absolutely nobody, no eyewitnesses have said so, nobody whose produced it. I was on the site, I was on the steelyards, so, I don't know that that's so. Steel melts at about two thousand six hundred degrees Fahrenheit. Um, I think it's pretty difficult to get that kind of temperatures in, ah, fire. So, I don't know the basis -- I can't address your question if I don't know the basis.
QUESTIONER: Well NASA pictures, ah, thermal imaging show those sorts of temperatures.
GROSS: Would you send them to me?
The reports of molten metal are numerous and were made by some of Gross' own colleagues, and the NASA thermal images that Gross implied he'd never seen have been featured on the USGS.gov website since 2001. The Top Ten Connections Between NIST and Nano-Thermites
1. NIST was working with LLNL to test and characterize these sol-gel nano-thermites, at least as early as 1999 (Tillotson et al 1999).
2. Forman Williams, the lead engineer on NIST’s advisory committee, and the most prominent engineering expert for Popular Mechanics
, is an expert on the deflagration of energetic materials and the “ignition of porous energetic materials”
3. Science Applications International (SAIC) is the DOD and Homeland Security contractor that supplied the largest contingent of non-governmental investigators to the NIST WTC investigation. SAIC has extensive links to nano-thermites, developing and judging nano-thermite research proposals for the military and other military contractors, and developing and formulating nano-thermites directly (Army 2008, DOD 2007). SAIC’s subsidiary Applied Ordnance Technology has done research on the ignition of nanothermites with lasers (Howard et al 2005).
In an interesting coincidence, SAIC was the firm that investigated the 1993 WTC bombing, boasting that -- “After the 1993 World Trade Center bombing, our blast analyses produced tangible results that helped identify those responsible (SAIC 2004).” And the coincidences with this company don’t stop there, as SAIC was responsible for evaluating the WTC for terrorism risks in 1986 as well (CRHC 2008). SAIC is also linked to the late 1990s security upgrades at the WTC, the Rudy Giuliani administration, and the anthrax incidents after 9/11, through former employees Jerome Hauer and Steven Hatfill.
4. Arden Bement, the metallurgist and expert on fuels and materials who was nominated as director of NIST by President George W. Bush in October 2001, was former deputy secretary of defense, former director of DARPA’s office of materials science, and former executive at TRW.
Of course, DOD and DARPA are both leaders in the production and use of nano-thermites (Amptiac 2002, DOD 2005). And military and aerospace contractor TRW has had a long collaboration with NASA laboratories in the development of energetic materials that are components of advanced propellants, like nano-gelled explosive materials (NASA 2001). TRW Aeronautics also made fireproof composites and high performance elastomer formulations, and worked with NASA to make energetic aerogels.
5. Hratch Semerjian, long-time director of NIST’s chemical division, was promoted to acting director of NIST in November 2004, and took over the WTC investigation until the completion of the report on the towers.
6. NIST has a long-standing partnership with NASA for the development of new nano-thermites and other nano-technological materials. In fact, Michael Zachariah coordinates this partnership (CNMM 2008).
7. In 2003, two years before the NIST WTC report was issued, the University of Maryland College Park (UMCP) and NIST signed a memorandum of understanding to develop nano-technologies like nano-thermites (NIST 2003). Together, NIST and UMCP have done much work on nano-thermites (NM2 2008).
8. NIST has their own Center for Nanoscale Science and Technology (CNST 2008). Additionally, NIST’s Reactive Flows Group did research on nanostructured materials and high temperature reactions in the mid-nineties (NRFG 1996).
9. Richard Gann, who did the final editing of the NIST WTC report, managed a project called “Next-Generation Fire Suppression Technology Program”, both before and after 9/11. Andrzej Miziolek, another of the world’s leading experts on nano-thermites (Amptiac 2002), is the author of “Defense Applications of Nanomaterials”, and also worked on Richard Gann’s fire suppression project (Gann 2002).
10. As part of the Federal Laboratory Consortium for Technology Transfer, NIST partners with the Naval Surface Warfare Center at Indian Head (NSWC-IH) on Chemical Science and Technology (FLCTT 2008). NSWC-IH is probably the most prominent US center for nano-thermite technology (NSWC 2008). In 1999, Jan Puszynski, a scientist working for the DURINT program, helped NSWC-IH design a pilot plant to produce nano-size aluminum powder. It was reported that “At that time, this was [the] only reliable source of aluminum nanopowders in the United States”
Molten metal? What molten metal?
NIST, in its final report on WTC 7, ignored all of the evidence relating to molten metal, even though numerous reliable witnesses spoke of the presence of molten metal at Ground Zero. These witnesses included Richard Garlock, a structural engineer at Leslie E. Robertson Associates, an engineering firm involved in the design of the towers and the clean up of the site, who said "Here WTC 6 is over my head. The debris past the columns was red-hot, molten, running." 10
The witnesses to molten metal also included University of California, Berkeley engineering professor Abolhassan Astaneh-Asl, who was the first scientist given access to the steel at ground zero. Dr. Astaneh-Asl referred to the WTC steel he found as "kind of melted. " 11 Years later, when asked again about his experience he clarified, "I saw melting of girders in World Trade Center." 12
There are many other reports of molten metal at ground zero, including quite a few from those who support the Bush Administration's ever-changing fire-induced collapse theories. There are also photos supporting the reports of molten metal. 13 But NIST continues to ignore all of this evidence in its new report.
Paper thin steel and sulfidation? What paper thin steel and sulfidation?
Since the WTC report from the Federal Emergency Management Administration (FEMA) came out in 2002, the most intriguing aspect of the official stories given was the problem that the New York Times called "perhaps the deepest mystery uncovered in the investigation." 14 This mystery referred to the extremely thinned pieces of steel discovered by FEMA investigators, and also by Astaneh-Asl. 15 These samples were found to exhibit sulfidation, and evidence of a eutectic formation, that could not be explained by any of the "fire-wise" professors.
Sivaraj Shyam Sunder did have to answer a question about [ the sulfidated steel discovered by FEMA ] in his recent press conference. Sunder simply said that those fire-wise professors had thought more about it, and told the BBC that it wasn't a mystery after all.
We can be sure that those professors did think more about it. But without the detailed study they originally called for, the deepest mystery remains officially unsolved.
Explosive thermite? What explosive thermite?
An actual explanation for the sulfidation and extreme thinning of steel has been offered by independent investigators, and is fully consistent with the alternative theory that NIST has avoided all these years.
When asked about thermite in the WTC 7 press conference, Sunder pretended that NIST was not aware of the explosive forms of this chemical mixture, called super-thermite or nano-thermite. Instead, Sunder claimed that thermite could not be applied adequately in order to serve the purpose of a deceptive demolition. Sunder's answer, apart from being vague and unsupported, is also in direct contradiction to the fact that a number of the NIST WTC investigation leaders had expert knowledge of nano-thermites, and that such materials can be sprayed onto surfaces like steel.
When presented with evidence of explosives, NIST has done the opposite of investigating: It has denied, evaded, changed the subject, and produced straw-man arguments. The message is clear: don't be troubled by those pesky facts like explosives residues -- Sunder and his team of experts have what you need. "It's simple, straightforward, it's elegant, technical," and they're "comfortable with it".
Sunder's final remarks to the 2008 press conference wraps a blanket disqualification of "alternative theories" as incredible in a transparent appeal to authority:
