A Secret Service agent at the White House calls the District of Columbia Air National Guard (DCANG) at Andrews Air Force Base, near Washington, and asks it to launch fighter jets immediately. According to author Lynn Spencer, a report has been received at the White House from the FAA “that there are three planes unaccounted for,” and the Secret Service has therefore determined “it needs fighters up now.” It calls the DCANG to request these jets. [Spencer, 2008, pp. 236] Apparently around the same time, the DCANG receives a call from someone else at the White House—presumably another Secret Service agent—declaring the Washington area “a free-fire zone.” Lieutenant Colonel Marc Sasseville, one of the DCANG pilots, will later comment, “That meant we were given authority to use force, if the situation required it, in defense of the nation’s capital, its property, and people.” [Aviation Week and Space Technology, 9/9/2002] Between 10:38 a.m. and 11:11 a.m., five DCANG fighter jets will take off from Andrews to defend Washington (see (10:38 a.m.) September 11, 2001, 10:42 a.m. September 11, 2001, and 11:11 a.m. September 11, 2001). [9/11 Commission, 2004; 9/11 Commission, 2/17/2004; Vogel, 2007, pp. 446] The Secret Service contacted the DCANG several times earlier on, requesting that it launch fighters (see (Shortly After 9:04 a.m.) September 11, 2001, (Shortly After 9:33 a.m.) September 11, 2001, and (Shortly After 9:35 a.m.) September 11, 2001). [Filson, 2003, pp. 78; 9/11 Commission, 7/24/2004, pp. 465] Brigadier General David Wherley, the commander of the DC Air National Guard, has been on the phone with Secret Service agents at the White House, who have told him his jets should “turn away any airplane that attempts to fly within 20 miles of the Washington area,” and the pilots can use “whatever force is necessary” to prevent another aircraft hitting a building (see (10:15 a.m.) September 11, 2001 and (Between 10:16 a.m. and 10:35 a.m.) September 11, 2001).
