Architects & Engineers for 9/11 Truth (AE911Truth) is a nonprofit organization of architects, engineers, and affiliates dedicated to establishing the truth about the events of September 11, 2001.

Over three thousand architects and engineers have signed AE911Truth’s petition, demanding a truly independent investigation, including a full inquiry into the possible use of explosives that might have been the actual cause of the destruction of the World Trade Center Twin Towers and Building 7.

Read the new study, prepared by University of Alaska Fairbanks for AE911Truth, about the World Trade Center Building 7 collapse. The report concludes that the collapse of Building 7 was caused not by fire but rather by the near-simultaneous failure of every column in the building.
