The accusations of Gage’s organization are the typical hodgepodge of pseudo-scientific claims. Along with other esoteric and debunked technical arguments, he says that melted steel was visible at the Ground Zero site proving that the fires burned too hot to have been caused by jet fuel; that because the buildings collapsed at “near free fall speed” there must have been a controlled demolition; and that traces of a thermitereaction found in the World Trade Center debris proves that explosives were used.

All of Gage’s so-called evidence has been rebutted in peer-reviewed papers, by the Federal Emergency Management Agency, by the National Institute for Standards and Technology, by the American Society of Civil Engineers, by the 9/11 Commission Report, and, perhaps most memorably, by the 110-year-old engineering journal Popular Mechanics.

What is more interesting than these bizarre and debunked conspiracy theories is the way that Gage places his AIA membership front and center in his presentations. He seems to be attempting to cloak his organization in the officialdom of the venerable 155-year-old professional institution, even as AIA wants nothing to do with his organization. At the start of his latest film, he explains that he is “a licensed architect of over 20 years and member of the American Institute of Architects.”

Gage often seems to wield his AIA status in promoting his conspiracy theories. In making his case, he also regularly cites that more than 100 AIA members and at least six AIA Fellows have signed his petition calling for a new investigation. In total, Gage says that more than 1,700 of the petition’s roughly 16,000 signatures are from architects and engineers.

During the screening, Gage was at the very least intimating that his organization had been invited to AIA officially.

“I can’t tell you how grateful we were to have been accepted to be here in the boardroom at the national headquarters,” Gage said. “We hope this is the beginning of a very productive relationship.”

Aside from Gage, though, there was not a single other architect in the room, much less an official from AIA, or even another member. The 80-strong crowd was made up largely of members of the local 9/11 Truth movement and other political activists.

Gage was once warned by AIA not to spread the misimpression that there is a relationship between the two organizations, after he wrote a letter to Congress stating that more than 100 members of AIA who signed his petition were demanding a new investigation into 9/11.
