Last night, Steven E. Jones, Department of Physics and Astronomy, Brigham Young University was interviewed on MSNBC. He wasn't given enough time to make his points, but he said his paper is online. So here's a sample:
Why Indeed Did the WTC Buildings Collapse?
In writing this paper, I call for a serious investigation of the hypothesis that WTC 7 and the Twin Towers were brought down, not just by damage and fires, but through the use of pre-positioned explosives. I consider the official FEMA, NIST, and 9-11 Commission reports that fires plus damage alone caused complete collapses of all three buildings. And I present evidence for the explosive-demolition hypothesis, which is suggested by the available data, testable and falsifiable, and yet has not been analyzed in any of the reports funded by the US government.
Let’s start with the collapse of the 47-story WTC 7, which was never hit by a jet.
WTC 7 collapsed rapidly and symmetrically -- even though fires were randomly scattered in the building. WTC 7 fell about seven hours after the Towers collapsed, even though no major persistent fires were visible. There were twenty-four huge steel support columns inside WTC 7 as well as huge trusses, arranged asymmetrically, along with approximately 57 perimeter columns. (FEMA, 2002, chapter 5.) A symmetrical collapse, as observed, evidently requires the simultaneous “pulling” of most or all of the support columns. The Second Law of Thermodynamics implies that the likelihood of complete and symmetrical collapse due to random fires as in the “official” theory is small, since asymmetrical failure is so much more likely. On the other hand, a major goal of controlled demolition using explosives is the complete and symmetrical collapse of buildings.
A New York Times article entitled “Engineers are baffled over the collapse of 7 WTC; Steel members have been partly evaporated,” provides relevant data.
Experts said no building like it [WTC7], a modern, steel-reinforced high-rise, had ever collapsed because of an uncontrolled fire. (Glanz, 2001; emphasis added.)
That’s correct – no such steel-beam building had ever before (or since) completely collapsed due to fires! However, such complete, symmetrical collapses have indeed occurred many times before -- all of them due to pre-positioned explosives in a procedure called “implosion” or controlled demolition. What a surprise, then, for such an occurrence in downtown Manhattan— three skyscrapers completely collapsed on the same day, September 11, 2001.
