12:00 p.m. September 11, 2001: Defense Intelligence Agency Director Says Al-Qaeda Responsible for Attacks

The director of the Defense Intelligence Agency informs military leaders in the National Military Command Center (NMCC) at the Pentagon that al-Qaeda is responsible for the morning’s attacks. General Richard Myers, the vice chairman of the Joint Chiefs of Staff, will later describe: “At noon, Vice Admiral Tom Wilson, director of the Defense Intelligence Agency, confirmed what everybody at the conference table had already surmised: The attacks had undoubtedly come from al-Qaeda.” [Myers, 2009, pp. 156] Later in the day, Wilson will recall a relevant piece of intelligence “chatter” that was picked up a few months previously. When General Hugh Shelton, the chairman of the Joint Chiefs of Staff, arrives in the NMCC at 5:40 p.m. after returning from his aborted flight to Europe, he will ask Wilson, “Have we had any intel ‘squeaks’ on an attack like this—anything at all?” Wilson will reply: “The only possible hint of this coming was several months ago when we got a single intercept requesting jumbo jet training. Since then, there’s been nothing.” According to Myers, Wilson is “referring to the vast electronic signals data-mining operations of our intelligence community that targeted known terrorist networks, such as al-Qaeda and their allies.” [Myers, 2009, pp. 159]
