The catastrophic destruction of the World Trade Center complex is said by government reports to have resulted from structural failure due mainly to fires initiated by the impacts of the airplanes. A closer look at the evidence reveals a much more disturbing crime.

Apart from the fact that no steel-framed high-rise building has ever collapsed due to fire prior to or since Sept. 11, the manner in which the buildings came down is itself a substantial cause for re-investigation. A collapse due to fire would likely proceed gradually with large deformations visible in the building’s perimeter, with the building tipping over slowly in the direction of the steadily weakening structural members – to the path of least resistance.

Yet the Twin Towers both came down quite suddenly, without warning, and without any “jolts” that would indicate the upper mass impacting the lower mass. The smooth rate of descent was measured at 2/3 of free-fall. In other words, the building was accelerating (traveling faster and faster second by second) straight down through what should have been the path of greatest resistance – the 80,000 tons of structural steel below that was at least five times stronger than necessary to resist this load. Physicists and other experts agree that this could have happened only if the underlying supporting structures were removed ahead of the falling upper building mass. The National Institute of Standards and Technology (NIST) acknowledges that each building was destroyed in fewer than a dozen seconds, and that they “came down essentially in free-fall”.

Welcome to Architects & Engineers for 9/11 Truth. We are a non-partisan association of more than 1,700 A/Es, with about 16,000 affiliates from all over the world. We are technical professional representing more than 25,000 years of collective experience. We do not offer conspiracy theories. We do have serious questions about the official reports of the destruction of all three World Trade Center skyscrapers on 9/11. We are calling for a new independent investigation that includes all of the evidence that is missing from these building reports. We, along with other researchers and groups in the growing international 9/11 truth movement, have compiled critically important eyewitness testimony, photo, video, and scientific forensic evidence that has been ignored, falsified, or destroyed by individuals and agencies that were responsible to the public for a thorough transparent investigation.
