The collapse of the WTC

NOTE: The following letter was sent 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.

A Personal Decision
by Kevin Ryan
Have you ever found yourself caught between several hundred million people and their most cherished lies? After writing a letter to a government scientist, pleading with him to clarify a report of his work, I found myself in just that situation. The letter was circulated on the Internet and for a brief time I became a reluctant celebrity. Of course I stand behind what I wrote, although it was originally intended as a personal message, not an open letter. Since many have asked for clarification, here is my message to all.
To me, the report in question represents a decision point, not just for the US, but for humanity as a whole. We're at a point where we must decide if we will live consciously, or literally give up our entire reality for a thin veneer of lies. In the US these lies include cheap propaganda that passes for journalism, police-state measures that promise security, and mountains of debt that paint a picture of wealth. Additionally we've adopted many implicit self-deceptions, like the idea that we'll always enjoy a limitless share of the world's resources, no matter where these are located or who might disagree.
All people lie to themselves. It's one of the most important things we have yet to accept about our own nature. We lie to ourselves to justify our past actions, to protect our self-image, and to promote ourselves relative to others. This lying is at the root of many of our problems (e.g. nationalism and racism). Until we see this, and strive to understand if not control it, the resulting problems will continue unchecked and the outcome will be certain. Any organism or society that makes self-deception its modus operandi will make many bad, and ultimately fatal, decisions. The day will come when we are collectively fooling ourselves in such a way that we essentially trade everything we have for what's behind our fantasy curtain. It appears that day is near.
The official conspiracy theory of 9/11 is a key part of our current self-deception. More importantly, this story may be our last chance to see just how critical our situation is so that we can all stop, and begin working together to solve the real problems we face. These problems, for the US and the world as a whole, amount to a growing storm of factors including environmental changes, resource depletion, and growth in resource usage.[1,2] Undoubtedly the secret Energy Taskforce report of May 2001 would verify this, and help us to understand that our government is responding to some of these threats with a carefully laid out plan. This plan assumes that people cannot rise above their own natural, ego-based self-deception, and therefore few of us will survive the coming storm. In essence, they're betting against us.
Anyone who honestly looks at the evidence has difficulty finding anything in the official story of 9/11 that is believable. It's not just one or two strange twists or holes in the story, the whole thing is bogus from start to end.[3] In my previous job I was in a position to question one part, the collapse of three tall buildings due to fire. But this isn't really a chemistry or engineering problem, and may be best approached initially through statistics.
The three WTC buildings in question weren't all designed the same way and weren't all hit by airplanes. The only thing they seemed to have in common were relatively small and manageable fires, as indicated by the work of firefighters right up to the moment of collapse. From the government's report we know that only a small percentage of the supporting columns in each of the first two buildings were severed, and that the jet fuel burned off in just a few minutes.
To follow the latest 'leading hypothesis', what are the odds that all the fireproofing fell off in just the right places, even far from the point of impact? Without much test data, let's say it's one in a thousand. And what are the odds that the office furnishings converged to supply highly directed and (somehow) forced-oxygen fires at very precise points on the remaining columns? Is it another one in a thousand? What is the chance that those points would then all soften in unison, and give way perfectly, so that the highly dubious 'progressive global collapse' theory could be born? I wouldn't even care to guess. But finally, with well over a hundred fires in tall buildings through history, what are the chances that the first, second and third incidents of fire-induced collapse would all occur on the same day? Let's say it's one in a million. Considering just these few points we're looking at a one in a trillion chance, using generous estimates and not really considering the third building (no plane, no jet fuel, different construction).
How convenient that our miraculous result, combined with several other trains of similarly unlikely events, gives us reason to invade the few most strategically important lands for the production of oil and natural gas. As I said, this is not about chemistry or engineering. Our continued dependence on this highly improbable story means that we have a desperate need to believe it. It is, in fact, a psychology problem.
Solving the problem is a personal challenge, and involves at least three-steps. First, we have to admit we were wrong, and that we were fooled. This is not easy for most people, but congratulations to the neo-cons for noticing that their political opponents seem to be least able to admit they were wrong on any significant issue. Secondly, we have to see that terrorism is actually much worse than we feared because the terrorists are in charge. Such a pause on a national scale would be dramatic to say the least. If we get to the third step we begin to realize the scope of change necessary to move forward in a conscious manner. Obviously the US government must be substantially changed and/or forgiven. New cooperative, multinational agreements would need to be implemented immediately.[4]
If you make it through step one and care enough about people to work for step three, you may face ridicule and isolation. You may lose your income and some friends, but if we continue down the same path there's a real chance you're going to lose those anyway. On the upside you may be able to hold on to some sense of integrity. The only thing you can be certain of is that we're all in this together. No matter how you voted, what credentials or positions you hold, or what faith you have in people, you will face the consequences of our collective self-deceptions. Now is the time for each of us to decide between a stormy reality and what's behind the fantasy curtain.

In other words, the government's "9/11 conspiracy theory" that al-Qaeda destroyed the WTC buildings is based upon fantasy instead of accepted scientific and engineering principles. And too few people are willing to risk their jobs to tell us the truth.
