A new 126 pages study by Leroy Hulsey, Zhili Quan, and Feng Xiao (all PhDs from University of Alaska Fairbanks) shows that World Trade Center Building 7 did not collapse due to fire:

"The principal conclusion of our study is that fire did not cause the collapse of WTC 7 on 9/11, contrary to the conclusions of NIST [National Institute of Standards and Technology] and private engineering firms that studied the collapse."

“The secondary conclusion of our study is that the collapse of WTC 7 was a global failure involving the near-simultaneous failure of every column in the building.”
