An E-3 Sentry AWACS aircraft from the 963rd Airborne Air Control Squadron at Tinker Air Force Base, Okla., sits on the flightline at Mountain Home Air Force Base, Idaho, Sept. 21, 2009, during Gunfighter Flag. The AWACS aircrew participated as friendly "blue air" forces during the exercise. Gunfighter Flag, which ran from Sept. 14 through 24, was Mountain Home's first large-scale, multi-national exercise which brought more than 450 personnel from the U.S. Air Force, U.S. Navy and Canadian air force to the base.
