Navy Vice Admiral Edmund Giambastiani Jr., who is Defense Secretary Donald Rumsfeld’s senior military assistant, returned to his office after attending a breakfast meeting hosted by the secretary of defense (see (8:00 a.m.-8:50 a.m.) September 11, 2001). After learning the second WTC tower has been hit, he says, he realizes “it [is] no longer an accident.” Stephen Cambone, who is Rumsfeld’s closest aide, comes to Giambastiani’s office, which is located near to the defense secretary’s office. Reportedly, he is there “to discuss the Pentagon as a potential target and their course of action if it was attacked.” Then, “Minutes later,” the attack on the Pentagon occurs. [American Forces Press Service, 9/8/2006] Cambone is also reported as being at the Pentagon’s Executive Support Center (ESC), located down the hallway from Rumsfeld’s office, some time between when the attacks on the South Tower and the Pentagon occur (see Shortly After 9:03 a.m. September 11, 2001). [Clarke, 2006, pp. 219-220] It is unclear whether he goes to the ESC before meeting with Giambastiani, or afterwards. Despite Cambone’s concern that the Pentagon could be a target, no attempt is made to evacuate the place before it is struck (see Before 9:37 a.m. September 11, 2001), and it does not appear that any alarms are sounded either.
