Can over a thousand engineers and architects be wrong?

Former senator, engineers offer ‘proof’ of 9/11 controlled demolitions

But a group of more than 1,200 architects and engineers is building what it hopes is a scientifically sound argument about one 9/11 claim: That the World Trade Center buildings were destroyed not by fires caused by the airplane collisions, but by a controlled demolition.

At a press conference in Washington DC, Thursday, the group Architects and Engineers for 9/11 Truth offered evidence "that all three WTC skyscrapers on September 11, 2001, in NYC were destroyed by explosive controlled demolition."

San Francisco architect Richard Gage said the way the towers collapsed was consistent with a controlled demolition, not a chaotic structural collapse.

"The official FEMA and NIST reports provide insufficient, contradictory, and fraudulent accounts of the circumstances of the towers' destruction," Gage said. "We are therefore calling for a grand jury investigation of NIST officials."

But Gage added that "government investigators at the NIST have been forced to acknowledge the free-fall descent, an indicting fact, after being presented with analysis by AE911Truth petition signers."

On its Web site, the architects' and engineers' group lists facts that suggest explosives were used to take down the towers.

-- Rapid onset of "collapse"
-- Sounds of explosions at ground floor - a second before the building's destruction
-- Symmetrical "structural failure" -- through the path of greatest resistance -- at free-fall acceleration
-- Massive volume of expanding pyroclastic dust clouds
-- Expert corroboration from the top European Controlled Demolition professional
-- FEMA finds rapid oxidation and intergranular melting on structural steel samples

WTC7 exhibited none of the characteristics of destruction by fire, i.e.
-- Slow onset with large visible deformations
-- Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, to the side most damaged by the fires)
-- High-rise buildings with much larger, hotter, and longer lasting fires have never "collapsed".
