An organization advocating the 9/11 conspiracy theory that the collapses of three World Trade Center buildings on September 11, 2001 were controlled demolitions.

AE911Truth was founded by Richard Gage to gather the endorsements of as many architects and engineers as possible for the organization’s assertions. Their stated goal is to force the creation of a “truly independent investigation with subpoena power” into the collapses of the Twin Towers and Building 7. All current endorsements are displayed at their website, launched in May 2007 and substantially redesigned in 2008. Gage wished to have 1,000 architects and engineers by September 11, 2008, but did not do so until January 2008.  As of July 1, 2010, the official numbers are “1218 architectural and engineering professionals and 8776 other supporters.”

The endorsements are gathered both at the website and at lectures by Richard Gage which promote the group’s arguments for controlled demolition. The website provides organizational materials, lists what they call technical articles supporting their positions, and gives the reader a chance to purchase AE911Truth merchandise and/or provide donations in several creative ways.
