One of the crucial technical disputes in American history, perhaps second only to global warming, is underway. It pits hundreds of government technicians who say the World Trade Center buildings were brought down by airplane impact against hundreds of professional architects and building engineers who insist that the Twin Towers could never have collapsed solely due to the planes and are calling for a new independent investigation. It is a fight that is not going away and is likely to get louder as more building trade professionals sign on to one side or the other. Better than anyone, David Ray Griffin understands the enormous importance" of Richard Gage, the Bay Area architect and staunch Republican who founded Architects and Engineers for 9/11 Truth (AE911 Truth). Griffin, [a] retired Santa Barbara philosophy professor/theologian (Claremont School of Theology), is regarded as the leading investigative force within what is called the 9/11 Truth movement, with seven 9/11 books to his credit, including his bestseller The New Pearl Harbor. Griffin found his greatest stumbling block in public appearances to be this question: If his analysis was true - that two planes could not have brought down three World Trade Center (WTC) buildings without the aid of pre-planted explosives - why didn't a single U.S. architect or building engineer publicly support him? Now, in three years, Gage has signed up 804 architects and structural engineers, some from top firms, who challenge the official version of the buildings' collapses. AE911 Truth has grown rapidly, igniting a struggling grassroots movement of hundreds of other "9/11 Truth" organizations, and spearheading a growing assault on the official story.
