Subject: 9/11 News - Expert challenges official WTC collapse theory

Dear 9/11 Trutch activists and concerned citizens,

With permission, we are forwarding you the following letter
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.

Towards peace and truth,

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.
