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.

This SEEMS to be a really important story by a UL scientist that asks some very very OBVIOUS questions regarding what looks to millions as ANOTHER HUGE FRAUD perpetuated on the American People, at least as concerns getting the full and active truth from 'government' concerning the DEMOLITION of the Towers.
I really just wanted to bump this back to the top, as I hope it stays in the 'mainstream' and anyone with any further info regarding this will be inclined to share. |

There is NO WAY Jet Fuel took down those buildings. NO WAY.
Those planes were like Pencils penetrating a brick house. The intense GRID in those structures were designed to withstand the impact of a loaded Boeing 707..the largest commercial jumbo jet before the 747 was made.
Firefighters and victims of the tragedy all reported multiple explosions going off at the site.
My guess is lt is very likely C-4 "pineapples" on the colums and stress points, and micro nukes were used.
Its the only explanation for the INTENSE fires that burned for 5 days underneath the rubble. It certainly wasn't "jet fuel", much less the massive clouds of pulverized concrete billowing up from the basement floors. |

Now the "experts" say it was office furniture burning that brought down the towers.
http://www.nytimes.com/2005/04/05/nyregion/05cnd-wtc.html?hp&ex=1112760000&en=0b9c387f12dcdbd8&ei=5094&partner=homepage
Report on Trade Center Collapses Emphasizes Damage to Fireproofing
By TIMOTHY WILLIAMS
Published: April 5, 2005
The World Trade Center towers may have remained standing even after they were struck by aircraft if the impact had not dislodged fireproofing and if office furniture had not extended the life of the fires sparked by the jet fuel, a federal report released today concluded.
The report by the National Institute of Standards and Technology said its findings support the fact that the World Trade Center towers withstood the initial aircraft impact and "that they would have continued to remain standing indefinitely, but for another significant event such as the subsequent fires."
The agency was charged by Congress two years ago with investigating various aspects of the World Trade Center attacks on Sept. 1, 2001, including evacuation and rescue procedures, the quality of the buildings' steel, and how and why the buildings collapsed.
The group did not issue recommendations in its report today. It is scheduled to release the draft of its final report in June, followed by a final report with recommendations in September. The investigation has produced more than 10,000 pages of data, according to the agency.
The conclusions are in line with previous analyses that cited the intense heat of up to 800 degrees Fahrenheit as a central reason for the collapse - heat that would have been tempered if the fireproofing had not been stripped. But the report also said that while the architects of the towers had tested the impact of a Boeing 707 passenger jetliner crashing into the 80th floor of one of the buildings in 1964, they never envisioned the intense fires that engulfed the towers after the planes struck them.
The analysis released today concluded that there were about 8,900 people in the first World Trade Center tower and about 8,500 in the second tower. About 87 percent of the people were able to evacuate safely. The report found that of the approximately 2,567 victims, "20% or more ... may have been alive in the buildings just prior to their collapse."
Because only two of 198 elevators were working inside the towers after the jarring impact of the jet liners, those who had the best chance of safely evacuating from the floors not directly impacted were able to leave their offices relatively quickly, to find stairwells, and were in good enough physical shape to exit without resting between floors.
Still, the analysis determined that in the first tower, the average surviving occupant spent 48 seconds per floor descending the stairwell - 50 percent slower than the slowest speed predicted for non-emergency evacuations presented in a standard fire engineering text. Because of the slow pace of evacuation, the analysis said that had each of the towers been full -- or had about 25,000 employees in each -- the evacuation would have taken four hours and about 14,000 people would have died.
The report also found that the World Trade Center's high rise communication repeater was working properly, a finding that contradicts claims by some rescue workers.
The analysis found that while the impact of the planes destroyed and weakened the buildings' support columns, damaged water supply systems and dislodged fireproofing, the towers would have remained standing had it not been for the fires that weakened their support steel.
The report concluded that most of the fire damage was not caused directly by dispersed jet fuel from the aircraft, but by combustible office furniture inside the buildings.
"The jet fuel, which ignited the fires, was mostly consumed within the first few minutes after impact," the report stated. "The fires that burned for almost the entire time that the buildings remained standing were due mainly to burning building contents and, to a lesser extent, aircraft contents, not jet fuel."
The fires further weakened the support beams that caused floors to buckle and the buildings to list to the side. Without adequate fireproofing, the towers had little chance of surviving, the report found.
"The buildings would likely not have collapsed under the combined effects of aircraft impact and the subsequent jet fuel ignited multi-floor fires, if the fireproofing had not been dislodged or had been only minimally dislodged by aircraft impact," the report said.

Read the latest propaganda/report:
Latest Findings from NIST World Trade Center Investigation Released
Probable Collapse Sequences for Both Towers Finalized; Reports Issued for Three Projects
http://www.nist.gov/public_affairs/releases/wtc_briefing_april0505.htm
quote:
April 5, 2005
NEW YORK CITY—The Commerce Department’s National Institute of Standards and Technology (NIST) today presented its analysis of how the World Trade Center (WTC) towers collapsed after two aircraft were flown into the buildings by terrorists on Sept. 11, 2001. This is the most detailed examination of a building failure ever conducted.
“Like most building collapses, these events were the result of a combination of factors,” said Shyam Sunder, lead investigator for the agency’s building and fire safety investigation into the WTC disaster. “While the buildings were able to withstand the initial impact of the aircraft, the resulting fires that spread through the towers weakened support columns and floors that had fireproofing dislodged by the impacts. This eventually led to collapse as the perimeter columns were pulled inward by the sagging floors and buckled.”
