Between 10:00 a.m. and 10:27 a.m. September 11, 2001: Joint Chiefs Vice Chairman Myers Wants Confirmation that the Airborne Operations Center Has Taken Off

General Richard Myers, vice chairman of the Joint Chiefs of Staff, asks Colonel Matthew Klimow, his executive assistant, to check that the E-4B National Airborne Operations Center (NAOC) has been launched in response to the terrorist attacks. [Myers and McConnell, 2009, pp. 153-154] Myers arrived at the National Military Command Center at the Pentagon with Klimow at around 9:58 a.m. and then joined the air threat conference (see (9:58 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 ; 9/11 Commission, 2/17/2004 ; 9/11 Commission, 7/24/2004, pp. 38] At 9:59 a.m., an Air Force officer at the White House stated over the air threat conference that Deputy National Security Adviser Stephen Hadley had requested the implementation of “Continuity of Government” (COG) measures (see 9:59 a.m. September 11, 2001). These measures are meant to be taken “only in the gravest of emergencies,” Myers will later note, “and most recently had been expected to meet the Cold War threat of nuclear attack.”
Assistant Is Told to Verify that the NAOC Is Airborne – One aspect of the government’s COG plan is launching the NAOC. [9/11 Commission, 7/24/2004, pp. 38; Myers and McConnell, 2009, pp. 153] The NAOC is a militarized version of a Boeing 747 that is intended to provide the president, secretary of defense, and Joint Chiefs of Staff with an airborne command center that could be used to execute war plans and coordinate government operations during a national emergency. The Joint Chiefs of Staff is responsible for directing NAOC operations. [Federation of American Scientists, 4/23/2000; Verton, 2003, pp. 143; United States Air Force, 8/2007] “Some in Washington considered it an expensive, unnecessary relic of the Cold War, but with the capital itself now under imminent threat, it was clear that NAOC was still a useful part of the inventory,” Myers will comment. In response to Hadley’s request, therefore, he asks Klimow to verify that the NAOC is airborne, according to his own recollection. [Myers and McConnell, 2009, pp. 154] Klimow, though, will give a slightly different account, recalling that Myers turns to him and says, “Call Strategic Command and have him scramble the NAOC.” [George C. Marshall European Center for Security Studies, 8/3/2012]
NAOC Planes Were Involved in an Exercise – The US military in fact possesses four NAOC planes and three of them are already airborne. Two of them took off from Andrews Air Force Base, just outside Washington, DC, at 9:27 a.m. and 9:45 a.m. (see (9:27 a.m.) September 11, 2001 and (9:45 a.m.) September 11, 2001), and the third took off from Wright-Patterson Air Force Base in Ohio minutes after the Pentagon attack, which occurred at 9:37 a.m. (see Shortly After 9:37 a.m. September 11, 2001). [Federation of American Scientists, 4/23/2000; Federal Aviation Administration, 9/11/2001 ; Dayton Daily News, 9/12/2001; 9/11 Commission, 2/17/2004] Furthermore, while Myers will imply that the NAOC was launched as part of COG measures, according to the Omaha World-Herald, the three aircraft took off because they were being used in a major training exercise called Global Guardian, which was being conducted by the US Strategic Command this morning (see Before 9:00 a.m. September 11, 2001). [Omaha World-Herald, 2/27/2002] The exact time when Myers talks about the NAOC with Klimow is unclear. However, he apparently does so before 10:28 a.m., since, in his 2009 memoir, he will place the conversation before he sees the North Tower of the World Trade Center collapsing on television, and the collapse occurs at 10:28 a.m. (see 10:28 a.m. September 11, 2001).
