REPOST FOR THOSE NEEDING BACKGROUND INFORMATION

Now it's the Underwriters Laboratories which refute the official cause of the collapse of the WTC on 9/11.

How can we then be expected to believe the official cause of the collapse?

I, for one, do not.

9/11 VISIBILITY PROJECT

The collapse of the WTC

The following letter was sent today by Kevin Ryan of Underwriters Laboratories <http://www.ul.com>

to Frank Gayle of the National Institute of Standards and Technology (NIST)

<http://www.nist.gov>.

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.

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.

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. Why Dr. Brown would imply that 2000F would melt the high-grade steel used in those buildings makes no sense at all.

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.
