Late in the evening of September 13, 2001, search and rescue operations at the Pentagon have to be temporarily suspended when—after firefighters thought they had the crash site under control—a sizeable fire breaks out, sending smoke hundreds of feet into the air. [CNN, 9/13/2001; Associated Press, 9/14/2001; CNN, 9/14/2001; NPR, 9/14/2001] The fire erupts in the pile of debris at the impact area where the aircraft hit the Pentagon, and is apparently caused by a “hot spot” that reignited. Fire commanders had been concerned about the smoke coming from the pile earlier in the evening, yet there is no engine available to extinguish any fire. There was an engine by the pile all through the day, but this left at the end of the day shift. Because of tightened security, the engine due to replace it is taking longer than usual to arrive. [Creed and Newman, 2008, pp. 389 and 393] The order goes out: “We need everybody to evacuate. The building is on fire again.” Firefighters and workers for agencies such as the FBI and FEMA evacuate, either to the lawn in front of the crash site or the Pentagon’s center courtyard. Yet the fire appears to be contained in the rubble pile, with little danger of spreading. One worker questions: “So why are they stopping us? Why can’t we keep working?” [Creed and Newman, 2008, pp. 393-394 and 400-401] Eventually, a fire truck arrives to tackle the blaze. About two hours after it first flared up, the fire is out and recovery workers can continue their activities. [CNN, 9/14/2001; Creed and Newman, 2008, pp. 394-395 and 401] Firefighting and other rescue operations were also significantly disrupted three times during September 11-12, due to false alarms over unidentified aircraft approaching Washington (see (10:15 a.m.-10:38 a.m.) September 11, 2001, (2:00 p.m.) September 11, 2001, and (10:00 a.m.) September 12, 2001).
