609th Air Intelligence Squadron

An intelligence officer with the District of Columbia Air National Guard (DCANG) at Andrews Air Force Base, 10 miles outside Washington, is unable to obtain further information about the attacks from other agencies, and instead has to make do with what he can learn from television reports. [Filson, 2003, pp. 79; Spencer, 2008, pp. 155-156] Having learned of the two attacks in New York, Major David McNulty, the senior intelligence officer of the 113th Wing of the DCANG, checks the SIPRNET—the Department of Defense’s classified version of the Internet—for pertinent information, but apparently without success. He phones anyone he can think of who might be able to provide information, including the Air Combat Command Intelligence Squadron at Langley Air Force Base in Virginia, the 609th Air Intelligence Squadron at Shaw Air Force Base in South Carolina, the FBI field office in Washington, and the Secret Service’s White House Joint Operations Center. Yet, as he will later recall, the agencies have “nothing to report.” Even his call to the FBI is “a fruitless effort.” [9/11 Commission, 3/11/2004 ; Spencer, 2008, pp. 155-156] McNulty will say, “I even called the National Security Agency 24-hour information desk and they knew nothing more than I did.” He adds, “We were all getting our information from CNN.” [Filson, 2003, pp. 79] According to Knight Ridder, “Air defense around Washington, DC, is provided mainly by fighter planes from Andrews Air Force Base.” [Knight Ridder, 9/11/2001] However, author Lynn Spencer will claim that because the DCANG “is a general purpose F-16 unit, no one is specifically tasked with keeping the squadron informed.” [Spencer, 2008, pp. 156]
