Since I graduated from Iowa State (BSAE ’64), I have retained a great deal of respect for the laws of physics. An understanding of those principles has allowed us to build skyscrapers, bridge rivers and land on the moon. We know that if a falling object accelerates at 32 ft/sec/sec there is nothing resisting its fall.

But the laws of physics were ignored by the National Institute of Standards and Technology (NIST) when it released its official report on the destruction of World Trade Center Building 7 on Sept. 11, 2001. An airplane did not hit this building. Although NIST acknowledged that the top of the building accelerated downward at 32 ft/sec/sec it did not explain why. The most logical explanation of why the 40,000 tons of structural steel in this 47-story building offered no resistance to falling is that the supporting structure was removed through controlled demolition using explosives.

Compelling scientific evidence has been uncovered in recent years that point to the use of high-tech explosives on 9/11. Our homeland will not be secure until there is a full investigation into how terrorists planted explosives in this building and the Twin Towers. Architects & Engineers for 9/11 Truth (ae911truth.org) has presented a petition to Congress calling for a new investigation signed by more than 1400 architects and engineers plus 11,000 other supporters.

You can hear a presentation of evidence given by Richard Gage, AIA, founder of AE911Truth, here in Ames at 7 p.m. April 3 in the Ames City Auditorium.
