Ryan was wrong. He was a lab manager at Underwriters Laboratories. His area was environmental testing, not structural certification or fire engineering. It doesn’t matter how many more times you post this letter over and over, he is still wrong.
When he was fired, he had been promoted to the top management job in his division, Environmental Health Laboratories, overseeing all company functions. I'm not sure if his division dealt with steel, but what I -do- know is that what you know isn't necessarily a part of your job description; what happened on 9/11 captivated the attention of many people and seeing as how the company he worked for had certified the steel, the issue of how the steel held up was of a more then a passing interest to him. He explains his learning of the subject in the years following 9/11 in his article "
Propping Up the War on Terror":

NIST and Underwriters Laboratories
In August 2004, Underwriters Laboratories evaluated the Pancake Theory by testing models of the floor assemblies used in the WTC buildings. Despite all the previous expert testimony, the floor models did not collapse. NIST reported this in its October 2004 update, in a table of results that clearly showed that the floors did not fail and that, therefore, pancaking was not possible.14 NIST more succinctly stated this again in its June 2005 draft report, saying: "The results established that this type of assembly was capable of sustaining a large gravity load, without collapsing, for a substantial period of time relative to the duration of the fires in any given location on September 11th."15
At the time of the floor tests, I worked for Underwriters Laboratories (UL). I was very interested in the progress of these tests, having already asked some sensitive questions. My interest began when UL's CEO, Loring Knoblauch, a very experienced executive with a law degree from Harvard, surprised us at the company's South Bend location, just a few weeks after 9/11, by saying that UL had certified the steel used in the WTC buildings. Knoblauch told us that we should all be proud that the buildings had stood for so long under such intense conditions. In retrospect it is clear that all of us, including Knoblauch, were ignorant of many important facts surrounding 9/11 and did not, therefore, see his statements as particularly important.
Over the next two years, however, I learned more about the issues, like the unprecedented destruction of the steel evidence and the fact that no tall steel-frame buildings have ever collapsed due to fire... Perhaps most compelling for me were the words of a genuine expert on the WTC. This was John Skilling, the structural engineer responsible for designing the towers.17 (The NOVA video, incidentally, gave this credit to Leslie Robertson. But Robertson, who never claimed to have originated the design, was only a junior member of the firm [Worthington, Skilling, Helle and Jackson], and Skilling was known at the time to be the engineer in charge.) In 1993, five years before his death, Skilling said that he had performed an analysis on jet plane crashes and the ensuing fires and that "the building structure would still be there."18
By 2003, all of this information was available to anyone who cared. The details were, without a doubt, difficult to reconcile with testimony from officials, reporters, and scientists who were supporting the official story. But in November of that year, I felt that answers from UL were needed. If, as our CEO had suggested, our company had tested samples of steel components and listed the results in the UL Fire Resistance Directory almost forty years ago, Mr. Skilling would have depended on these results to ensure that the buildings were sufficiently fire resistant. So I sent a formal written message to our chief executive, outlining my thoughts and asking what he was doing to protect our reputation.
Knoblauch's written response contained several points. He wrote: "We test to the code requirements, and the steel clearly met those requirements and exceeded them." He pointed to the NYC code used at the time of the WTC construction, which required fire resistance times of 3 hours for building columns, and 2 hours for floors. From the start, his answers were not helping to explain fire-induced collapse in 56 minutes (the time it took WTC2, the South Tower, to come down). But he did give a better explanation of UL's involvement in testing the WTC steel, even talking about the quality of the sample and how well it did. "We tested the steel with all the required fireproofing on," he wrote, "and it did beautifully."19
This response was copied to several UL executives, including Tom Chapin, the manager of UL's Fire Protection division. Chapin reminded me that UL was the "leader in fire research testing," but he clearly did not want to make any commitments on the issue. He talked about the floor assemblies, how these had not been UL tested, and he made the misleading claim that UL does not certify structural steel. But even an introductory textbook lists UL as one of the few important organizations supporting codes and specifications because they "produce a Fire Resistance Index with hourly ratings for beams, columns, floors, roofs, walls and partitions tested in accordance with ASTM Standard E119."20 He went on to clarify that UL tests assemblies of which steel is a component. This is a bit like saying "we don't crash test the car door, we crash test the whole car." In any case, Chapin suggested that we be patient and wait for the report from NIST, because the investigation into the "collapse of WTC buildings 1, 2, and 7" was an ongoing process and that "UL is right in the middle of these activities."21
For the most part, I did wait, although I shared my concerns with Chapin again at UL's Leadership Summit in January 2004. I encouraged him to ask for a company news release on our position, but this did not happen and I never heard from him again. By the time UL tested the floor assembly models in August of that year, I had been promoted to the top management job in my division, Environmental Health Laboratories, overseeing all company functions. Two months later, NIST released an official update that included the floor test results, as well as Frank Gayle's results, in which steel temperatures were predicted. These results clearly invalidated the major theories of collapse, because pancaking could not occur without floor collapse and steel does not turn to licorice at the temperatures discussed.
After reviewing this update, I sent a letter directly to Dr. Gayle at NIST. In this letter, I referred to my experiences at UL and asked for more information on the WTC investigation and NIST's soon-to-be-published conclusions. NIST had planned at the time to release its final report in December, with time allowed for public comment. After I allowed my letter to become public,22 this date was moved to January 2005, and then nothing was heard from NIST for several months.
Other than UL's involvement in testing the steel components, the facts I stated had all been reported publicly, but when I put them together plainly, they were considered outrageous. Five days after I sent my letter, I was fired by UL for doing so. The company made a few brief statements in an attempt to discredit me, then quickly began to make it clear that its relationship with the government, perhaps due to its tax-exempt status, was more important than its commitment to public safety...
