Douglas Gerald Hurley (born October 21, 1966) is an American engineer, former Marine Corps pilot, and former NASA astronaut. He piloted Space Shuttle missions STS-127 (July 2009) and STS-135 (July 2011), the final flight of the Space Shuttle program. He launched into space for the third time as commander of Crew Dragon Demo-2, the first crewed spaceflight from American soil since STS-135 and became, together with Bob Behnken, the first astronaut in history launching aboard a commercial orbital spacecraft. He was also the first Marine to fly the F/A-18 E/F Super Hornet. His call sign is "Chunky", and he was sometimes referred to by this name on the communication loops.
