(10:10 a.m.) September 11, 2001: Military Put on High Alert

All US military forces are ordered to Defcon Three (or Defcon Delta), “The highest alert for the nuclear arsenal in 30 years.” [Daily Telegraph, 12/16/2001; CNN, 9/4/2002; ABC News, 9/11/2002; Clarke, 2004, pp. 15] Rumsfeld claims that he makes the recommendation, but it is hard to see how he can do this, at least at this time. He later asserts that he discusses the issue with acting Joint Chiefs of Staff Chairman Richard Myers in the NMCC first. However, they do not arrive at the PEOC until about 10:30 a.m. [9/11 Commission, 3/23/2004] At 10:15 a.m., the massive blast doors to US Strategic Command, headquarters for NORAD in Cheyenne Mountain, Colorado, are closed for the first time in response to the high alert. [Aviation Week and Space Technology, 6/3/2002; BBC, 9/1/2002] In another account, acting Joint Chiefs of Staff Chairman Richard Myers gives the Defcon order by himself. President Bush later contradicts both accounts, asserting that he gives the order. [Wall Street Journal, 3/22/2004 ] According to the 9/11 Commission’s final report, though, the decision to go to Defcon Three takes place about 35 minutes later (see (10:43 a.m.) September 11, 2001).
