"Never in history has a steel frame building come down from fire"
uhh, nevermind the jumbo jet impact and the unparalleled quantity of fuel added.

Interesting that there have been no responses yet, but three flags on this.
I don't believe what this man is saying is true. There have been many books out that have debunked these conspiracy theories on 9/11.
Aren't there any computer simulations that can pinpoint exactly how the WTC towers fell?
"the phenomenon that we saw on 9/11 that brought this particular building down was really thermal expansion, which occurs at lower temperatures.

Dear Mr. Bob
This letter serves a the final response to your Freedom of Information Act (FOIA) request (Log#10-194) to the National Institute of Standards and Technology (NIST), in which you requested
in connection with its investigation for the technical cause of the collapse of the World Trade Center Tower and World Trade Center Building 7 on September 1,200I:
'1. All input and results files of the ANSYS 16 story collapse initiation model with detailed connection models that were used to analyze the structural response to thermal loads, break element source code, ANSYS script files for the break element s, custom executable ANSYS file, and all Excel spreadsheets and other supporting calculations used to develop floor connection failure modes and capacities.
2. All input files with connection material properties and all results flies of the LS-DYNA 47-story global collapse model that were used to simulate sequential structural failures leading to collapse and all Excel spreadsheets and other supporting calculations used to develop floor connection failure modes and capacities."
NIST is withholding sixty-eight thousand, two hundred and forty-six (68,246) file. These records are currently exempt from disclosure under section (b)(3) of the FOlA., 5 .S.C § 552 (b)(3). Exemption (b)(3) permits an agency to withhold records in an agency's possession which are records that are "specifically exempted from disclosure by statute (other than 5 .S.C552(b», provided that such statute (A) requires that the matters be withheld from the public in such a manner as to leave no discretion on the issue, or (B) establishes particular criteria for
withholding or refers to particular types of matters to be ...withheld."
The statute underlying the (b)(3) exemption in this case is the at National Construction Safety Team (1 C T) Act, 15 .S.. § 7301 et seq_ Section 12 of the CST Act (ISS_C § 7311) provides that it applies to the activities of 1ST in response to the attacks of September I ), 200 I. Section 7(d) of the NIST Act (15 U.S.C § 7306(d», exempts from disclosure. information received by 1ST in the course of investigations regarding building failures if the Director finds that the disclosure of the information might jeopardize public safety. On July 9 2009 the Director of NIST determined that release of the withheld information might' jeopardize public safety. Therefore, these records are being withheld.
You have the right to appeal this determination. Such an appeal must be made in writing and received within 30 calendar days of the date on this letter addressed to:
Assistant General Counsel for Administration (Office)
U.S. Department of Commerce
14th and Constitution Avenue, N.W. Washington, D.C. 20230
Your appeal should include a copy of you original request,a copy of this determination,and a statement of the reason(s) you believe this determination to be in error and why these records should be made fully available 10 you. Both your letter and the envelope in which it is mailed should be prominently marked "Freedom of Information Act Appeal.!!

Of course it can - but what do melted beams have to do with the WTC?
FEMA Appendix C,
Limited Metallurgical Examination.
Evidence of a severe high temperature corrosion attack on the
steel, including oxidation and sulfidation with subsequent
intergranular melting, was readily visible in the near-surface
microstructure….. A liquid eutectic mixture containing primarily
iron, oxygen, and sulfur formed during this hot corrosion attack on the steel.
The thinning of the steel occurred by high temperature corrosion due to a
combination of oxidation and sulfidation.
"steel members with unusual erosion patterns were observed in the WTC debris field"..."severe erosion found in several beams warranted further consideration"
This sulfur-rich liquid penetrated preferentially down grain boundaries of the steel, severely weakening the beam and making it susceptible to erosion.......The severe corrosion and subsequent erosion of Samples 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been identified. The rate of corrosion is also unknown."
"as this piece was clearly in a prone position during the corrosive attack and was located no higher than the 53 floor of the building, this degradation phenomenon has no bearing on the weakening of the steel structure or the collapse of the building"NCSTAR1-3C pp.233
"No conclusive evidence was found to indicate that pre-collapse fires were sever enough to have a significant effect on the microstructure that would have resulted in weakening of the steel structure." NIST NCSTAR 1-3C, p. 235
no evidence the type of joining methods, materials, or welding procedures used was improper NIST 1-3 p.99
recovered bolts were stronger than typical. NIST 1-2 p.133
"no core column examined showed temp. above 250C" NIST 1-3 6.6.2
NCSTAR1-3 7.7.2 "because no steel was recovered from WTC7,it is not possable to make any statements about it's quality"
These 9-11 conspiracy threads are the worst trash this site has to offer. Pathetic.

not an open air hydrocarbon fire....as these were, doesn't burn hot enough......never has, never will.
MIGHT jeopardize public safety??????

He lacks the years of schooling that it takes to get a degree in engineering. Like the people who say that this was MOST LIKELY not a controlled demolition.
You can't say "OH, he was there, so that makes him infallible in his testimony."
I respect him for his service to the public, and this man is braver that 99% of the population. But I don't think he knows what he is talking about.
But within half an hour or so the MSM was quoting the famous Harley guy that was supposedly just a citizen on the street.
He took the time to explain the "Pancake Theory" to us peons on National news and on every channel.
And I ask this......What were his qualifications that day?
