“Did Building 7 collapse from fires? The answer is no.”
—Dr. Leroy Hulsey , the University of Alaska Fairbanks
From YouTube: Dr. Leroy Hulsey presents the findings of his WTC 7 Evaluation study at the Justice in Focus 9/11 Symposium in New York on Sep 10, 2016. The WTC 7 Evaluation is a study at the University of Alaska Fairbanks using finite element modeling to evaluate the possible causes of World Trade Center Building 7’s collapse.

Anyone who has followed this issue knows that NIST’s explanation of thermal expansion of a floor beam causing Column 79 to become dislodged leading to the symmetrical collapse of the entire building, including 2.2 seconds of free fall, is unscientific.
Thanks to Dr. Hulsey for his detailed analysis of why this is so. We need more analyses like this that use real data and that do not treat weak hypotheses as scientific conclusions.
