The 9/11 Commission initially pays very little attention to material from the NSA about al-Qaeda, as it is focusing on the CIA, FBI, and other agencies. Colonel Lorry Fenner, a former air force intelligence officer assigned to the commission’s team reviewing the structure of the intelligence community, finds this surprising. Fenner, who had previously worked closely with the NSA, is “dumfounded” when she learns nobody from the commission is making the short trip to the NSA to review its material on 9/11. The NSA tracked al-Qaeda communications for a long time before 9/11, including numerous calls between the hijackers and other al-Qaeda operatives (see Early 2000-Summer 2001), but the 9/11 Commission apparently does not realize or seem to care how important the material is. Author Philip Shenon will comment: “[F]or the Commission’s staff, [the NSA’s Maryland headquarters at] Fort Meade might as well have been Kabul, it seemed so distant.” One reason is that some people at the commission do not really understand what the NSA does, and also, according to Shenon, “[For executive director Philip] Zelikow and other staff on the commission, it was just more interesting—sexier—to concentrate on the CIA.” [Shenon, 2008, pp. 87-88, 155-6]
