The Tower Builder
On September 11th, each building took the impact of a 767 (which is nearly twenty per cent heavier than a 707) and stood long enough to allow most of the people below the crash sites—the ninety-fourth floor to the ninety-ninth floor in the north tower, and the seventy-eighth floor to the eighty-fourth floor in the south tower—to escape. Had the buildings toppled immediately, nearly all those survivors would have died, and there would have been huge losses as well in the buildings and streets around the towers. The fact that the terrorists chose to hit the buildings on opposite faces suggests to some that they intended to knock the buildings over—which would have increased the destruction and loss of life. "Ninety-nine per cent of all buildings would collapse immediately when hit by a 767," Jon Magnusson said.
