Group Of Engineers Believe Controlled Detonations Took Down World Trade Center

By Paul Kurtz

BLACKWOOD, N.J. (CBS) - There's been a growing movement led by some architects and engineers to take a second look at the collapse of the New York City skyscrapers in the attacks on September 11th 2001.

"Architects and Engineers for 911 Truth" focuses primarily on Building 7 of the World Trade Center. Not many people know that a third building fell on 9-11. Tony Szambotti is a mechanical engineer from Blackwood, New Jersey. He says the 47 story skyscraper was not hit by a plane...yet collapsed into its own footprint at 5:20 in the afternoon.

"It's in absolute freefall. There's no resistance to it for the first 2.25 seconds and then it slows down a little bit," Szambotti said. "The actual measurements are somewhere around 6.6 to 7 seconds for that 610 foot building to collapse completely to the ground."

Szambotti and some 2,000 other of his colleagues contend that it was not scientifically possible for an office fire to be hot enough to melt steel girders and columns. Which brings these highly educated, white-collar professionals to a disturbing conclusion.

"We believe there were pre-planted charges in the building."

The group doesn't speculate as to who may have planted charges, but it's launching a new campaign today to spur a new investigation.

"We would like, whoever had access to those buildings to be investigated and that has never been done."

"Rethink 911" features a daylong rally beneath a new billboard in Times Square and 11 other cities to drum up support for the investigation.
