in Dayton, Ohio. Among his duties was to serve at the Directorate of Flight and All-Weather Testing. There he specialized in the development and flight testing of experimental automatic flight control systems. He graduated from the Air Force Experimental Flight Test Pilot School (Class 56C) in 1957, flying F-101 Voodoos, F-102 Delta Daggers, F-104 Starfighters, F-105 Thunderchiefs, F-106 Delta Darts and other jet fighters. Rushworth was selected for the X-15 program in 1958. He made his first flight on November 4, 1960. Over the next six years, he made 34 flights in the X-15, the most of any pilot. This included a flight to an altitude of 285,000 feet, made on June 27, 1963. This flight above 50 miles qualified Rushworth for Astronaut Wings, though he would have attained that honor sooner had the USAF Man In Space Soonest project proceeded according to plan. On a later X-15 flight, he was awarded a Distinguished Flying Cross for successfully landing a North American X-15 after its nose wheel extended while flying at nearly Mach 5. He made his final X-15 flight on July 1, 1966, then returned to regular Air Force duties. He attended F-4 Phantom II Combat Crew Training, went through survival training, and in March 1968 he was sent to Cam Ranh Bay Air Base, Republic of Vietnam, where he was Assistant Deputy Commander for Operations with the 12th Tactical Fighter Wing and flew 189 combat missions. Following his return from Vietnam, from April 1969 to January 1971, he was program director of the AGM-65 Maverick program and in February 1971 became Commander of the newly organized 4950th Test Wing, Aeronautical Systems Division at Wright-Patterson Air Force Base, Ohio. Rushworth then served as Inspector General, Air Force Systems Command, Andrews Air Force Base, Maryland, from May 1973 to February 1974. He also served as the Commander of the Air Force Flight Test Center at Edwards Air Force Base, California, where his responsibilities included the major test programs, including the F-5, A-10, F-15, YF-16, YF-17 and B-1, and as the Commander of the Air Force Test and Evaluation Center at Kirtland Air Force Base, New Mexico. At the time of his retirement as a major general, he was Vice Commander, Aeronautical Systems Division, Air Force Systems Command, at Wright-Patterson Air Force Base, Ohio, where he dealt directly with senior deputies and managers and assisted the management of major acquisition programs
