9:43 a.m. September 11, 2001: National Airborne Operations Center Plane Launches from Andrews Air Force Base

An E-4B National Airborne Operations Center plane, with the call signal “Venus 77,” is launched from Andrews Air Force Base, near Washington, in response to the Pentagon attack, and is initially directed toward Offutt Air Force Base in Omaha, Nebraska. Shortly after taking off, the plane’s pilot asks to change his destination to Wright-Patterson Air Force Base, near Dayton, Ohio. He is cleared to do so and turns west. At 9:47, the pilot will ask to turn back east and hold south of Washington. The plane will settle into a holding pattern over Richmond, Virginia, possibly waiting there to receive a decision on where to fly the president. This incident, which is recorded on air traffic control tapes, will first come to light in 2009, in the book The Ground Truth by John Farmer, the senior counsel to the 9/11 Commission. According to Farmer, Venus 77 is the “mystery plane” seen over Washington around this time (see (9:41 a.m.-9:42 a.m.) September 11, 2001). [Farmer, 2009, pp. 206-207, 372] However, journalist and author Dan Verton will write that an E-4B took off from “an airfield outside of the nation’s capital” slightly earlier on, apparently just before the time of the Pentagon attack (see (Shortly Before 9:37 a.m.) September 11, 2001). According to Verton, it was due to participate in “a previously scheduled Defense Department exercise.” [Verton, 2003, pp. 143-144] Whether that aircraft was Venus 77, described by Farmer, is unclear.
