The head of the agency that provides security at the Pentagon informs another military employee that the Pentagon is unprotected against an aerial attack. In reaction to the news of the attacks on New York, Army Deputy Administrative Assistant Sandra Riley telephones John Jester, the chief of the Defense Protective Service (DPS)—the law enforcement agency that guards the Pentagon. She asks him, “What do we have in place to protect from an airplane?” He tells her, “Nothing.” According to the Defense Department’s book about the Pentagon attack: “The Pentagon did not have an antiaircraft system on the roof of the building or on the grounds. Even if DPS had received word of an inbound plane, it had no plan to counter a suicide air attack. Had a warning been issued in time, DPS’s only effective response would have been evacuation and dispersal of the building’s occupants.” [Goldberg et al., 2007, pp. 152] The Washington Post will similarly claim the Pentagon has “no anti-aircraft guns posted on its roof, nor any radars of its own for tracking local air traffic.” [Washington Post, 9/16/2001] Yet, at the nearby White House, the Secret Service is believed to have a battery of ground-to-air Stinger missiles ready to defend the place.
