Three towers collapsed that day???

The third tower to fall on 9/11
by Bob Livingston


WTC 7 was a building that was part of the World Trade Center complex. It collapsed at 5:20 p.m. on Sept. 11, 2001, becoming the first skyscraper in the history of the world to collapse — according to the official explanation — due to fire.

At 47 stories, it was just under half as tall at the Twin Towers (each 110 stories). It collapsed in free-fall, appearing as a controlled demolition. It collapsed after the building’s owner, Larry Silverstein, told firefighters to “pull it” after having a discussion with his insurance carrier to determine if it would authorize its controlled demolition.

Setting up a controlled demolition cannot be accomplished in minutes or hours. It takes weeks and months of planning. So Silverstein must have known the explosives had been placed there ahead of time.

Both the Twin Towers exhibited all the characteristics of explosive demolition when they fell. Had they been brought down by fire, their collapse would have been asymmetrical. There would have been a slow onset of collapse with large and visible deformations present.

The Twin Towers, according structural engineers who designed them and carried out studies prior to their construction, concluded the buildings could withstand multiple impacts by 707s or DC 8s at speeds much greater than the 767-200s that struck the buildings. In January 2001, WTC Building Construction Manager Frank A. DeMartini, in an interview for History Chanel’s “Modern Marvels,” said the buildings could withstand the impact of a “fully loaded Boeing 707” because the structure is like mosquito netting and a plane would be like a pencil penetrating the netting...
