Employees in the Pentagon’s Building Operations Command Center (BOCC) do not realize a plane has hit their building, and are confused when over 300 of the Pentagon’s fire alarms go off at once. [Creed and Newman, 2008, pp. 31; WHYY-FM, 5/27/2008] The BOCC, located on the first floor of the Pentagon’s innermost corridor, is usually staffed by two or three people who constantly monitor the building’s utility systems. [Goldberg et al., 2007, pp. 137; Creed and Newman, 2008, pp. 31] In it, Steve Carter and Kathy Greenwell felt the building tremble and heard a dull explosion when the Pentagon was hit. Their computers then show that, in an instant, 335 fire alarms have gone off, including the alarm for the BOCC itself. As authors Patrick Creed and Rick Newman will describe: “That didn’t make sense. Normally, fire spreads slowly. If the computer was correct, 400,000 square feet of the Pentagon had erupted into flame all at once.” Creed and Newman describe the plane impact that has caused this: “As the mass [of the aircraft] traveled through the building, it began to resemble a shaped charge, a form of explosive that funnels its force into a small, directed area—like a beam of energy—in order to punch holes through armor or other strong material.” The entire event, from the moment of impact until the aircraft’s movement is arrested, has “taken place in eight-tenths of a second.” [Creed and Newman, 2008, pp. 29-31] Furthermore, an unusual pattern of explosions occurred when the aircraft struck the Pentagon. The Defense Department’s book about the attack will describe: “The Jet A fuel atomized and quickly combusted, causing explosive bursts as the plane hurtled into the building. A detonation 150 feet inside the building resulted from a ‘fuel-air’ explosion after the Jet A tanks disintegrated on impact. Here, as elsewhere, there was no uniform pattern of death and destruction. The vagaries of the fuel-air explosions and freakish blast effects meant deaths occurred randomly inside the Pentagon, with the occupants of seemingly more secure interior offices sometimes suffering worse fates than those nearer the outside wall.” [Goldberg et al., 2007, pp. 37] In the BOCC, not realizing what has happened, Carter says aloud: “I think we have a truck bomb! Or some kind of explosion!” [Creed and Newman, 2008, pp. 31] It is not until later in the day that he learns a plane hit the Pentagon. [WHYY-FM, 5/27/2008]
