After reading that Dutch demolition expert Danny Jowenko was absolutely certain that WTC7 was brought down by controlled demolitions, one should wonder what the official story is. NIST (National Institute of Standards and Technology), a branch of the Commerce Department, was in charge of studying the collapse of all three buildings that happened on 9/11. They released their final report in November of 2008, concluding that WTC7 collapsed due to fires. This was immediately challenged by Architects and Engineers who filed a request for the data that NIST used to reach their conclusion.
The problem is that NIST won't release the data, because it "might jeopardize public safety." Supposedly they're afraid that terrorists might learn how to bring down skyscrapers by starting office fires.
Of course, by refusing to release their data, they also make it impossible for architects and engineers to study it and learn how to design buildings so that they don't collapse from office fires. Or as professional engineer Wayne H. Coste put it:
"Suppressing this analysis from peer review is unconscionable. Public safety is endangered when engineers are precluded from studying how an ordinary office fire could completely and utterly destroy a forty-seven-story modem skyscraper such that for more that 100 feet it exhibited free-fall acceleration."
So who to believe? Demolition expert Danny Jowenko, along with 1500 architects and engineers, who say that WTC7 was brought down by controlled demolition, or NIST, who refuses to release the data that supposedly supports their conclusion that office fires are to blame?
