With the support of a group called Architects and engineers for 911 Truth, Professor Leroy Hulsey of the University of Alaska at Fairbanks conducted an independent study whose findings were released in 2020. Professor Hulsey found that office fires of the kind in building 7 on 911 could not have produced sufficient thermal expansion to cause the crucial girder to fail. It's impossible, he found. And more significantly, he and his team found that NIST's explanation does not account for what anyone can see on video, which is that the entire building came down all at once. (09:20–09:30)
