Richard Gage, AIA, founder of Architects and Engineers for 9/11 Truth visits the National Institute of Standards and Technology after NIST's lead investigator for the World Trade Center disaster, Shyam Sunder, declines to meet with him. Gage hand-delivers a letter written to Dr. Sunder that raises serious objections to the official NIST explanations for the three World Trade Center high-rise building collapses on 9/11. Gage is accompanied by AE911Truth members Matt Skarlatos and David Slesinger.
