In this Dec. 21, 2007 photograph, C. Gordon Fullerton capped an almost 50-year flying career, including more than 38 years with NASA, with a final flight in a NASA F/A-18. Fullerton, who was a NASA astronaut, research pilot and Air Force test pilot, died Aug. 21, 2013. He was 76. On this mission, Fullerton and Dryden research pilot Jim Smolka flew a 90-minute pilot proficiency formation aerobatics flight with another Dryden F/A-18 and a Dryden T-38, concluding with two low-level formation flyovers of NASA's Dryden Flight Research Center before landing. Fullerton was honored with a water-cannon spray arch provided by two fire trucks from the Edwards Air Force Base fire department as he taxied the F/A-18 up to the Dryden ramp, and was then greeted by his wife Marie and several hundred Dryden staff after his final flight.
