(9:38 a.m.) September 11, 2001: ‘Experienced Combat Arms Officers’ at Pentagon Think a Bomb Has Exploded There

A group of Army officers at the Pentagon initially thinks that a bomb has gone off in their building when it is attacked. Army Major Craig Collier and his colleagues are in their office on the second floor of the Pentagon’s C Ring, about 200 feet from where the building is hit. Collier will later recall: “[T]he building jolted and we heard a muffled boom, then a rumble.… All of my peers in the area are experienced combat arms officers, and we quickly agreed that it sounded and felt like a bomb.” [Goldberg et al., 2007, pp. 26] Numerous other Pentagon employees also initially think a bomb has gone off, and apparently only a few guess a plane has hit the place (see (9:38 a.m.) September 11, 2001).
