Maj. Jon Williams, a mission crew commander, 963rd Expeditionary Airborne Air Control Squadron, on the E-3 Sentry Airborne Warning and Control System, or AWACS, reached 10,000 flying hours on the aircraft July 4, 2011, in Southwest Asia -- a feat that has only been achieved a handful of times since the aircraft became operational in the Air Force in 1977, two years before Williams joined the Air Force.
