Key Researcher Casts More Doubt On WTC Collapse

[hangloose]

SOUTH BEND, Ind.—A former laboratory director of a division of Underwriters Laboratories (UL) in South Bend generated considerable heat in professional circles on Nov. 11 when he fired off a letter via email to a prominent metallurgist, questioning the theory that jet fuel fires set by the 9-11 terrorist attacks against the World Trade Center were hot enough to soften or melt structural steel.

The federal probe postulates that burning jet fuel was a primary factor in the structural collapse that led to the “pancaking”-style, vertical demolition of the 110-story WTC towers on Sept. 11, 2001. However, any clear information that throws water on that theory is bound to furl some brows among those who accept the government’s story of how the WTC towers were destroyed.

“The buildings should have easily withstood the thermal stress caused by pools of burning jet fuel,” Ryan noted in his rather lengthy letter, referring to the results of performance tests on models of the floor assemblies used in the Twin Towers, as he described it. In the letter, Ryan refutes Dr. Hyman Brown from the WTC construction crew, who claims that the WTC buildings collapsed “due to fires at 2,000 F melting the steel.”

“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 3,000 F. Why Brown would imply that 2,000 F would melt the high-grade steel used in those buildings makes no sense at all.”

Ryan pointed out that the summary of the new findings “states that the perimeter columns softened, yet your findings make clear that ‘most perimeter panels (157 of 160) saw no temperature above 250 C.’ To soften steel for the purposes of forging, normally temperatures need to be above 1,100 C. However, this new summary report suggests that much lower temperatures were able to not only soften the steel in a matter of minutes, but lead to rapid structural collapse.”

In the letter to Gayle, Ryan added: “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 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 250 C suggests that the majority of deaths on 9-11 were due to a safety-related failure. That suggestion should be a great concern to my company.”

Noting that the events of 9-11 “are the emotional driving force behind the War on Terror,” and that the WTC collapse “is at the crux of the story of 9-11,” Ryan told Gayle: “My feeling is that your metallurgical tests are at the crux of the crux of the crux.”

Ryan summarized, “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.’ . . . Please do what you can to quickly eliminate the confusion regarding the ability of jet fuel fires to soften or melt structural steel.”

1. Interesting... At first I was sure this was about conspiracy theories...

I was wrong...

2. as some of us have been saying for several years now . . .

those planes were NOT the cause of the WTC tower collapses . . . that should be the starting point of a REAL investigation into what DID cause those buildings to fall -- at free fall speed -- into their own footprints . . .
