Richard Gage, AIA, Architect Member, American Institute of Architects. A practicing Architect for 20 years who has worked on most types of building construction including numerous fire-proofed steel-framed buildings. Founding member of Architects and Engineers for 9/11 Truth.
Speech at Sonoma State University 4/20/07: "Another 2006 poll by Scripps Howard, Ohio University, which found that a shocking 16% believe that the World Trade Center's Twin Towers were brought down by explosives. Unfortunately, my research has also concluded that this is true. Tonight I will present to you the very clear evidence that all three World Trade Center high-rise buildings, the Twin Towers and Building 7 were destroyed not by fire as our government has told us, but by controlled demolition with explosives."

Frank A. DeMartini WTC victim. Architect and WTC Construction Manager, North Tower, 88th floor. Demartini first worked at the World Trade Center when Leslie E. Robertson Associates hired him to assess damage from the terrorist truck bombing in 1993.
Video interview 1/25/01: "The [Twin Tower] building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door. This intense grid * and the jet-plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting."

Editor's note: The Boeing 767-200s that impacted the Twin Towers on 9/11 were only slightly larger than 707s and DC 8s, the types of jetliners whose
impacts the World Trade Center's designers anticipated. The maximum takeoff weight of the 707 is 15% less than the 767.

Statement in support of Architects and Engineers petition:
"Approximately 50% of my work is forensic. I am licensed in 9 States. In addition to my forensic work, a good portion of my work is in the design of structural fireproofing systems.
All three [WTC] collapses were very uniform in nature. Natural collapses due to unplanned events are not uniform."

Essay 12/06: "The NIST investigation of the WTC building failures was extensive, but NIST did not substantiate its conclusions experimentally. On the contrary, many of NISTs tests contradicted its conclusions. Furthermore, there are several examples in which NIST chose to manipulate input data, and then certify its findings based upon the inevitable conclusions that derive from the manipulated input. One finds little acknowledgement on the part of NIST that uncertainties in its simulations translate into uncertainties in its findings.
NISTs physical tests were inadequate. Their ASTM E119 tests and their workstation burn tests were improperly modeled. Further, the former produced results that contradicted NISTs conclusions and the latter fell far short of testing the performance of realistic steel members in the actual fire conditions. The workstation burn tests showed that the temperatures were generally too low, especially in the ventilation-controlled WTC environments. The ASTM E119 tests showed that the WTC floor trusses should have easily withstood the fires they experienced on 9/11.
There were also flaws in NISTs computer simulations, including its impact simulation, its fire loading simulation, its temperature mapping simulation, its thermal/structural component simulations, and its global simulation. The LS-DYNA simulation showed that the aircraft would have done much less damage than NIST assumes, and NISTs subsequent "scenario pruning" was confused and unsubstantiated. The decision to exclude the hat truss from the structural/thermal response simulations was a significant omission. The sequence of failed truss seats leading to pull-in forces on the exterior columns is central to NISTs theory but not explained or supported by simulation.
This paper will conclude that the findings of the NIST investigation, although not necessarily incorrect, are not inherently linked to the reality of the failure mechanisms that took place in WTC buildings 1 and 2. The author calls on NIST to explain the discrepancies in its reports, admit the level of uncertainty in its findings, broaden the scope of its investigation, and make its raw data available to other researchers."

"On Behalf of the People of the United States of America, the undersigned Architects and Engineers for 9/11 Truth and affiliates hereby petition for, and demand, a truly independent investigation with subpoena power in order to uncover the full truth surrounding the events of 9/11/01 - specifically the collapse of the World Trade Center Towers and Building 7. We believe that there is sufficient doubt about the official story and therefore that the 9/11 investigation must be re-opened and must include a full inquiry into the possible use of explosives that may have been the actual cause behind the destruction of the World Trade Center Towers and WTC Building 7." http://www.ae911truth.org/joinus.php

Endorsement of 9/11 Contradictions: An Open Letter to Congress and the Press by David Ray Griffin: "This book describes in very straightforward and non-technical terms some major inconsistencies in the government's official story about the events on September 11, 2001. It points out many attempts in the 9/11 Commission's report to cover up evidence. ... As an engineer, I am especially troubled by the cover-up of evidence relevant to the collapse of the three major World Trade Center buildings. I hope that Congress and the public will heed this call for a full and impartial investigation to determine what really did happen on that fateful day."

Statement in support of Architects and Engineers petition:
"Without any serious study I had simply accepted that the events of 9/11 were as commonly perceived, although I was not happy with the way the disaster was being used to promote what I felt were illegal and self defeating imperialistic policies in the guise of the War on Terrorism.
It was not until early 2006 that I stumbled upon sufficient information to become suspicious of the "official" and generally accepted 9/11 storyline. This led me to do my own investigation during which I discovered the demise of WTC 7, which I was heretofore unaware of. Obviously it was the result of controlled demolition and scheduled to take place during the confusion surrounding the days events.
I now feel morally obligated to deal with and expose the "politically unthinkable" issues surrounding the 9/11 phenomena by participating in such undertakings as signing this petition."

Editor's note: WTC Building 7 was 610 feet tall, 47 stories. It would have been the tallest building in 33 states. Although it was not hit by an airplane, it completely collapsed into a pile of rubble in less than 7 seconds at 5:20 p.m. on 9/11, seven hours after the collapses of the Twin Towers. However, no mention of its collapse appears in the 9/11 Commission's "full and complete account of the circumstances surrounding the September 11, 2001 terrorist attacks." Watch the collapse video here. And six years after 9/11, the Federal government has yet to publish its promised final report that explains the cause of its collapse.

Statement in support of Architects and Engineers petition:
"Being a civil engineer and understanding the laws of physics, I know that a building cannot fall at free fall speed without the floors already falling also giving no resistance. I wish our Congressmen were as smart, and also showed some backbone and got a truly independent investigation going. Also, this 911 truth movement has shown to me that our press is as every bit controlled and spits out as much propaganda as I thought Pravda did for the old Soviet Union. My eyes have been awakened to many things, and I have come to learn that we do not live in as free a country as I thought we did, and with the passage of the Patriot Act, the Military Commissions Act, it has become even less so."
