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 above 1100C (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.

November 12:
An executive of the company that certified the steel used in the construction
of the World Trade Center has questioned the common theory that fuel fires
caused its collapse, in a letter yesterday to the head of the government
team that has spent two years studying how the trade center was built and
why it fell.
The author of the letter, Kevin Ryan, is site manager at Environmental Health
Laboratories in South Bend, Indiana, a division of Underwriters Laboratories,
the product-compliance and testing giant. Because UL certified the WTC steel
for its ability to withstand fires, its performance on September 11 is obviously
of concern to the company.
Ryan sent his letter to Frank Gayle, deputy chief of the Metallurgy Division
at the National Institute of Standards and Technology (NIST). He later forwarded
it in an e-mail to David Ray Griffin, author of the New Pearl Harbor, and
Catherine Austin Fitts, who is a member of the 911Truth.org board.
Griffin asked for and received permission to forward the letter for Web
distribution. 911Truth.org called Ryan today to confirm his authorship.
The letter raises disturbing questions, pointing out that the steel in the
towers tested up to its certified standard (i.e., it should have easily withstood
the fuel fires without buckling).
A chemist by profession, Ryan said he is acting in the hope of receiving
a public response from Gayle. Given the impact of September 11 on events
around the world, Ryan said, everyone needs to know the full truth of what
really happened on that day. He added that he considers Gayle to be a good
scientist and an honest person.
A draft of the government agency's final report on the WTC collapse is due
in January.
The New York Times reports today that the NIST team is planning to hold some
of its deliberations in secret. "The announcement has been sharply protested
by advocates for families of the 9/11 victims, who said they were considering
a lawsuit to force the agency to open the meetings to the public," the Times
writes.
As the Times notes, the NIST investigation was started in 2002 after lobbying
by, among others, the Skyscraper Safety Campaign, an organization created
by Monica Gabrielle and Sally Regenhard, both of whom lost family on September
11.
Gabrielle told the Times that NIST should have "one job, and one job only
- to find out the truth of what happened to those buildings and to report
to the public about it. You don't owe industry, the Port Authority or federal
agencies anything. You owe it to the public - the truth, no matter where
it goes." (See www.nytimes.com)
