WTC Construction Certifiers Say Towers Should Have Easily Withstood Jet Fuel Temperatures

Kevin Ryan/Underwriters Laboratories | November 12 2004

The following letter was sent today by Kevin Ryan of Underwriters Laboratories to Frank Gayle of the National Institute of Standards and Technology (NIST). Underwriters Laboratories is the company that certified the steel componets used in the constuction of the World Trade Center towers. The information in this letter is of great importance.

Dr. Gayle,

Having recently reviewed your team’s report of 10/19/04, I felt the need to contact you directly.

As I’m sure you know, the company I work for certified the steel components used in the construction of the WTC buildings. In requesting information from both our CEO and Fire Protection business manager last year, I learned that they did not agree on the essential aspects of the story, except for one thing - that the samples we certified met all requirements. They suggested we all be patient and understand that UL was working with your team, and that tests would continue through this year. I’m aware of UL’s attempts to help, including performing tests on models of the floor assemblies. But the results of these tests appear to indicate that the buildings should have easily withstood the thermal stress caused by pools of burning jet fuel.

There continues to be a number of "experts" making public claims about how the WTC buildings fell. One such person, Dr. Hyman Brown from the WTC construction crew, claims that the buildings collapsed due to fires at 2000F melting the steel (1). He states "What caused the building to collapse is the airplane fuel...burning at 2,000 degrees Fahrenheit. The steel in that five-floor area melts." Additionally, the newspaper that quotes him says "Just-released preliminary findings from a National Institute of Standards and Technology study of the World Trade Center collapse support Brown’s theory."

We know that the steel components were certified to ASTM E119. The time temperature curves for this standard require the samples to be exposed to temperatures around 2000F for several hours. And as we all agree, the steel applied met those specifications. Additionally, I think we can all agree that even un-fireproofed steel will not melt until reaching red-hot temperatures of nearly 3000F (2). Why Dr. Brown would imply that 2000F would melt the high-grade steel used in those buildings makes no sense at all.

The results of your recently published metallurgical tests seem to clear things up (3), and support your team’s August 2003 update as detailed by the Associated Press (4), in which you were ready to "rule out weak steel as a contributing factor in the collapse." The evaluation of paint deformation and spheroidization seem very straightforward, and you noted that the samples available were adequate for the investigation. Your comments suggest that the steel was probably exposed to temperatures of only about 500F (250C), which is what one might expect from a thermodynamic analysis of the situation.

However the summary of the new NIST report seems to ignore your findings, as it suggests that these low temperatures caused exposed bits of the building’s steel core to "soften and buckle." (5) Additionally this summary states that the perimeter columns softened, yet your findings make clear that "most perimeter panels (157 of 160) saw no temperature above 250C." To soften steel for the purposes of forging, normally temperatures need to be above1100C (6). However, this new summary report suggests that much lower temperatures were be able to not only soften the steel in a matter of minutes, but lead to rapid structural collapse.

This story just does not add up. If steel from those buildings did soften or melt, I’m sure we can all agree that this was certainly not due to jet fuel fires of any kind, let alone the briefly burning fires in those towers. That fact should be of great concern to all Americans. Alternatively, the contention that this steel did fail at temperatures around 250C suggests that the majority of deaths on 9/11 were due to a safety-related failure. That suggestion should be of great concern to my company.

There is no question that the events of 9/11 are the emotional driving force behind the War on Terror. And the issue of the WTC collapse is at the crux of the story of 9/11. My feeling is that your metallurgical tests are at the crux of the crux of the crux. Either you can make sense of what really happened to those buildings, and communicate this quickly, or we all face the same destruction and despair that come from global decisions based on disinformation and “chatter”.

Thanks for your efforts to determine what happened on that day. You may know that there are a number of other current and former government employees that have risked a great deal to help us to know the truth. I’ve copied one of these people on this message as a sign of respect and support. I believe your work could also be a nucleus of fact around which the truth, and thereby global peace and justice, can grow again. Please do what you can to quickly eliminate the confusion regarding the ability of jet fuel fires to soften or melt structural steel.

  • So, were the buildings detonated by experts implouding inward like the missile that hit thePentagon or are you "dancing around the truth with your hand on my butt" to make your point? Who conspired toblow up the towers to draw attention to a war that they wanted? Isn’t that a better way of putting the matter? You will never prove anything! Perhaps in 200 years, should your country last that long, the truth will come out.

  • All news i hear now,all movies i see,I allmost routinely snore off,nothing matters now,everething is so trivial,cause there bluff has has been called.The jig is up.I hope people realize 911 was the equivelent of the Reistag in Nazi Germany,only we can watch the movies of the era and ask why didn’t they do anything?Yea its hard to wake people up,I can barely tell my own family without rolling eyes.I Cannot tell them what I realize without freeking them out.

  • Ask your friends and family to do their own little investigation. See if they can find anyone who has ever been able to make a call on a cell phone while on an airplane. Or, if they know any pilots, ask them if they would be able to find Manhatten (never mind the WTC’s) with transponders turned off and no help from any air traffic controllers. These two points were never really looked into by the MSM.

  • In order to sustain the official lie that the twin towers were destroyed by burning jet fuel on 9/11, the citizens of this nation had to be made or kept deeply ignorant and disinclined towards learning the truth and the evidence supporting the truth. The american people made an immense blunder when they did not use the rather large window of opportunity after 9/11 to exercise critical thinking and their right to ask questions of their leaders concerning the discrepancies between the implausible official explanation and the truth of the visual and physical evidence left in the wake of the attacks. There is no possibility that standing pools of burning kerosine based jet fuel could have produced the required high temperatures necessary to bring about the melting or weakening of the steel support columns in the twin towers. The maximum temperature achieved by the combustion of a mixture of jet fuel and large quantities of fast moving oxygen within a jet engine in flight does not exceed 1600-1700ºF, therefore it is impossible for burning jet fuel to reach 2000ºF while puddled in an oxygen poor and stagnant environment such as the basements of the twin towers. It is an immutable fact that burning jet fuel(or any fuel for that matter) that is subjected to a fast moving large quantity of oxygen burns at far higher temperatures than does the same fuel burning in standing oxygen starved conditions. The only way that this reality can be inverted is though the cultivation of ignorance and superstition and constant repetition of big lies to the point where perceptions are altered slowly but surely to make possible the acceptance of the new false paradigm. The bush regime counted upon the lack of comprehensive basic knowledge of scientific principles and the absence of the desire to become better informed in these principles in the general public to guarantee the successful reinforcement of their deceptions. Their expectations were confirmed and they were amply rewarded by the cattle-like reactions of the petrified citizenry. Only ignorant and gullible people believe that all the laws of physics were suspended on 9/11 and made possible a chain of events that defied logic and common sense. We are expected to believe that burning jet fuel from two large aircraft that slammed into the twin towers led to the collapses of three buildings in a manner that has never happened before or since then anywhere else in the world. There is too much evidence about the collapses of the WTC buildings and the Pentagon crash on 9/11 that are being kept secret by the bush regime that should and must be made public and investigated thoroughly to arrive at the truth. The people should never have accepted the bush mafia’s stock and illegitimate pretense that “national security would have been compromised and the nation put in jeopardy of further terrorist attacks from the release of the evidence” because it sounded just like the kind of vile alibis that mafia kingpins or dictators utilize to justify their attempts to impede the public exposure of their complicity in a gigantic crime and the imposition of punishment for their wanton acts of murder. In the insane new reality we live in now, irrational superstition is considered the new science and the lying and murdering liars who redefine reality from moment to moment have declared themselves the new scientists. Those of us who know the difference between objective scientific truths and lies and can hold onto them in the face of immense pressure to do otherwise from the monolithic Big Brother-like bush regime are the Winston Smiths of the real world who must defeat every potential O’Brien lurking out there.
