On September 11, 2001, a large commercial aircraft traveling at high speed crashed into the Pentagon. The aircraft struck essentially at the second story slab, damaging columns on the first and second story and the slab of the second story in the outer ring of the structure. Then the aircraft debris slid under the second floor, 94.5 m (310 ft) into the building, inducing significant damage to the three outer rings of the west side of the Pentagon. Numerous columns were removed or significantly damaged by the aircraft debris as it moved through the building. As a result, a portion of the outer ring collapsed approximately 20 minutes after the crash. This paper summarizes the condition of the building after the attack.
