Abstract

On September 11, 2001, an airliner was intentionally crashed into the Pentagon. It struck at the first elevated slab on the west wall, and slid approximately 310 ft (94.5 m) diagonally into the building. The force of the collision demolished numerous columns and the fa ade of the exterior wall, and induced damage to first-floor columns and the first elevated slab over an area approximately 90 ft (27.4 m) wide and 310 ft (94.5 m) long. None of the building collapsed immediately. The portion that remained standing, even after an intense fire, sustained substantial damage at the first-floor level.
