(10:30 a.m.-1:00 p.m.) September 11, 2001: Defense Secretary Rumsfeld Works on Rules of Engagement for Fighter Pilots, Too Late to Be of Any Use

After he finally arrives at the National Military Command Center in the Pentagon (see (10:30 a.m.) September 11, 2001), Donald Rumsfeld’s primary concern, according to the 9/11 Commission, is “ensuring that the [military fighter] pilots [have] a clear understanding of their rules of engagement.” [9/11 Commission, 7/24/2004, pp. 44] Rumsfeld later recalls, “It was clear they needed rules of engagement telling them what they should and should not do. They needed clarity. And there were no rules of engagement on the books for this first-time situation where civilian aircraft were seized and were being used as missiles.” By this time, the president has supposedly already given authorization for the military to shoot down hijacked aircraft (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001), and Dick Cheney informs Rumsfeld of this over the air threat conference at 10:39 (see 10:39 a.m. September 11, 2001). Rumsfeld says that, “Throughout the course of the day,” along with acting Joint Chiefs of Staff Chairman Richard Myers, he “returned to further refine those rules.” [9/11 Commission, 3/23/2004] As journalist Andrew Cockburn will later remark though, Rumsfeld’s work on the rules of engagement “was an irrelevant exercise for he did not complete and issue them until 1:00 p.m., hours after the last hijacker had died.” [9/11 Commission, 7/24/2004, pp. 465; Cockburn, 2007, pp. 7]
