In the National Military Command Center (NMCC) at the Pentagon, personnel apparently become aware of the first attack on the World Trade Center from watching the reports on television. According to Steve Hahn, an operations officer there, “We monitor the television networks in the center, and along with the rest of America we saw the smoke pouring from the tower.” Dan Mangino, who is also an operations officer at the NMCC, says, “At first, we thought it was a terrible accident.” [American Forces Press Service, 9/7/2006] The 9/11 Commission later says, “Most federal agencies learned about the crash in New York from CNN.” [9/11 Commission, 7/24/2004, pp. 35] Whether the NMCC was already aware that a hijacking was underway is unclear. According to military instructions, the NMCC is “the focal point within Department of Defense for providing assistance” in response to hijackings in US airspace, and is supposed to be “notified by the most expeditious means by the FAA.” [US Department of Defense, 6/1/2001 
] Boston Air Traffic Control Center started notifying the chain of command of the suspected hijacking of Flight 11 more than 20 minutes earlier (see 8:25 a.m. September 11, 2001). And at 8:32, the FAA’s Command Center in Herndon informed FAA headquarters of the possible hijacking (see 8:28 a.m. September 11, 2001). Yet, according to the 9/11 Commission, although the “FAA headquarters began to follow the hijack protocol,” it “did not contact the NMCC to request a fighter escort.” Supposedly, the first that the military learned of the hijacking was when Boston Air Traffic Control Center contacted NORAD’s Northeast Air Defense Sector (NEADS) about it, at around 8:37 a.m. (see (8:37 a.m.) September 11, 2001). The earliest time mentioned by the 9/11 Commission that the NMCC learns of the Flight 11 hijacking is 9 a.m. (see 9:00 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 19-20 and 35]
9:03 a.m. September 11, 2001: Pentagon Command Center Staff See Second Attack on WTC, Yet Accounts Conflict Over Urgency of Their Response
Those in the National Military Command Center (NMCC) within the Pentagon see the second plane hitting the World Trade Center live on television. According to Dan Mangino, an operations officer at the center, the staff there had thought the first WTC crash was a “terrible accident,” but after seeing the second one, “we knew immediately that it was a terrorist attack.” The American Forces Press Service later reports, “Personnel in the center shifted into hyperdrive.… Phones in the center began ringing off the hook.” Mangino says he initiates “the process to stand up a working group in advance of the direction that would come down later.” One of his deputies is responsible for this process. Yet, despite this supposed urgency, Mangino later recalls that he “knew he would have little time in the days ahead, so he quickly ran to the concourse to get some money out of an automated teller machine.” He will not arrive back at the NMCC until after the Pentagon is hit. [American Forces Press Service, 9/7/2006] Brigadier General Montague Winfield had earlier on allowed a colleague to temporarily take over from him as the NMCC’s deputy director for operations (see 8:30 a.m. September 11, 2001). Yet, despite the obvious emergency now taking place, he does not retake charge of the center until more than an hour later, at around 10:15-10:30 a.m. (see (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 6/17/2004] Furthermore, according to the 9/11 Commission, the NMCC does not begin a “significant event” conference call in response to the attacks until 9:29 a.m., which is 26 minutes after the South Tower is hit (see 9:29 a.m.-9:34 a.m. September 11, 2001).

Shortly After 9:37 a.m. September 11, 2001: Officer in Pentagon Command Center Only Learns from TV that Pentagon Has Been Hit
The Pentagon’s National Military Command Center (NMCC) is located on the other side of the building to where it is hit. Therefore, when the attack on the Pentagon occurs, those inside it supposedly do not feel the impact. [CNN, 9/4/2002] According to Newsweek, the NMCC has been called “the primary nerve system” of the Pentagon, from where “commanders can monitor and communicate with American forces around the world.” [Newsweek, 9/28/2001] A military instruction for dealing with hijacked aircraft describes it as “the focal point within Department of Defense for providing assistance” in response to hijackings. [US Department of Defense, 6/1/2001 ] But supposedly NMCC personnel do not initially realize the Pentagon has been attacked. Steve Hahn, an operations officer at the center, later says, “I didn’t know [the Pentagon had been hit] until I heard the news report on television.” [American Forces Press Service, 9/7/2006] Yet an article in the New York Times later claims, “During the hour or so that American Airlines Flight 77 was under the control of hijackers, up to the moment it struck the west side of the Pentagon, military officials in [the NMCC] were urgently talking to law enforcement and air traffic control officials about what to do” (see (Shortly After 8:51 a.m.) September 11, 2001). [New York Times, 9/15/2001] Furthermore, at about 8:50 a.m. according to the FAA, or 9:20 a.m. according to the 9/11 Commission, the FAA had established several phone bridges linking key players, including the NMCC (see (8:50 a.m.) September 11, 2001) (see (9:20 a.m.) September 11, 2001). The FAA states that it shares “real-time information on the phone bridges,” which includes “actions being taken by all the flights of interest, including Flight 77.” [9/11 Commission, 5/23/2003; 9/11 Commission, 7/24/2004, pp. 36] Why NMCC personnel do not therefore know immediately that the Pentagon has been hit is unclear. Also around this time, Officer Aubrey Davis of the Pentagon police is outside Donald Rumsfeld’s office. He hears what he later describes as “an incredibly loud ‘boom,’” when the Pentagon is struck (see 9:38 a.m. September 11, 2001). Yet no mention is made of anyone in the NMCC hearing this “boom,” even though the center is located only around 200 feet from where Davis is standing. [WBZ Radio 1030 (Boston), 9/15/2001; Cockburn, 2007, pp. 1] Dan Mangino, an operations officer in the NMCC, went out earlier to withdraw some money from a cash machine (see 9:03 a.m. September 11, 2001), and rushes back to the center after the Pentagon is hit. He finds the people in it are very calm. He says, “There was no panic, no raised voices. We train for emergencies all the time, and that training took over.” [American Forces Press Service, 9/7/2006]
