'''The Pentagon''' is a five-sided military compound and headquarters of the [[United States Department of Defense]]. It is located just north of [[Washington, D.C.]] in [[Arlington]], [[Virginia]]. It is home to the offices of the [[U.S. Joint Chiefs of Staff]], the Secretary of Defense, and the [[Joint Terrorism Task Force]]. During the terrorist attacks on September 11, 2001, hijackers crashed American Airlines Flight 77 into the west side of the Pentagon. The crash damaged three of the five sides of the Pentagon. Because the affected area was under renovation at the time, several offices were unoccupied, sparing many lives. The Pentagon has since been repaired and the first workers whose offices were damaged in the attack began moving back in on August 15, 2002, nearly a month ahead of schedule.
