When Flight 77 hits the Pentagon, it misses the parts of the building known to house the military’s most senior leaders. Journalist and author Steve Vogel later says, “The hijackers had not hit the River or Mall sides” of the building, “where the senior military leadership had been concentrated since 1942.” At the time of the attack, Secretary of Defense Donald Rumsfeld is “sitting in the same third-floor office above the River Entrance as every secretary of defense since Louis Johnson in 1949, a location that had been a matter of public record all that time. The joint chiefs and all the service secretaries were arrayed in various prime E-Ring offices on the River and Mall sides.” Furthermore, “All the command centers save the Navy’s were on the River or Mall sides; the National Military Command Center could have been decimated as the Navy Command Center was, a disaster that could have effectively shut down the Pentagon as the first American war of the twenty-first century began.” Instead, the area hit comprises Army accounting offices, the Navy Command Center, and the Defense Intelligence Agency’s comptroller’s office.
