>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.
