Just a few years ago Ed Munyak, a fire protection engineer for the city of San Jose, seemed like a lonely, out-there figure, a sometimes-target because of his outspoken position on the events of Sept. 11, 2001. These days, hundreds of other building trade professionals have joined him in challenging the official narrative about the collapse of three buildings at New York's World Trade Center (WTC) on that fateful, traumatic day. Munyak, of Los Altos Hills, is a mechanical and fire engineer whose job is to review building plans to ensure they comply with the California Building and Fire Code. In 2007, after speaking out on his own for a few years, Munyak signed on with a then-fledging organization called Architects and Engineers for 911 Truth, founded by Bay Area architect Richard Gage. Today, far from being isolated, Munyak now counts as allies 804 professional architects and building engineers from around the country. Collectively, they have joined Munyak's call for an independent technical investigation of the causes of the WTC buildings collapse. In doing so, they reject the federal government's conclusions that two airplanes alone brought the buildings down-without the aid of pre-planted explosives. Munyak and his fellow AE911 supporters recently received acknowledgement from the FBI's counterterrorism division, which concluded that the organization's core evidence deserves-and will get-FBI scrutiny. In a letter, Deputy Director Michael J. Heimbach assessed AE911's presentation as "backed by thorough research and analysis."
