World Trade Center Building 7 was the third skyscraper to collapse completely, rapidly and symmetrically on 9/11. In 2008, a high school physics teacher provided evidence to overturn the government's story on the collapse of WTC7 by demonstrating a period of free fall acceleration. International teams of independent scientists, including the U.S.G.S., have all confirmed the existence of military-grade high-temperature incendiaries in all post-9/11 WTC dust samples. From the point of view of highly - credible professionals (including National Award of Science recipient Dr. Lynn Margulis), as well as a truly compelling look at the reasons why people have difficulty with this evidence from psychologists, explaining all of the available technical evidence in startling clarity and detail.
