Donald E. Williams

American astronaut (1942–2016)

Donald E. Williams logged a total of 287 hours and 35 minutes in space across two shuttle missions. A career military officer and test pilot, he bridged the transition between tactical carrier operations in Vietnam and the technical complexities of the National Aeronautics and Space Administration flight programs during the 1980s.

Military Aviation and Combat Service

Born in Lafayette, Indiana, in 1942, Williams attended Purdue University, where he earned a degree in mechanical engineering in 1964. He received his commission through the Naval ROTC program and earned his Naval Aviator wings in 1966. His career included four deployments during the Vietnam War, where he flew the A-4 Skyhawk and A-7 Corsair II from the aircraft carrier USS Enterprise.

Test Pilot and NASA Selection

In 1974, Williams graduated from the United States Naval Test Pilot School at NAS Patuxent River. His subsequent work involved evaluating carrier suitability and strike aircraft. NASA selected him as an astronaut candidate in 1978. He officially qualified as an astronaut in 1979, taking on roles in the Shuttle Avionics Integration Laboratory and participating in operations at the Kennedy Space Center.

Spaceflight Missions

Williams served as the pilot for STS-51-D aboard the Discovery in 1985, a mission that included the first unscheduled EVA performed by the shuttle to recover a satellite. During this flight, he became the first person to juggle in micro-gravity. In 1989, he acted as spacecraft commander for STS-34, which utilized the Atlantis to deploy the Galileo spacecraft toward Jupiter and map atmospheric ozone.

Later Years and Legacy

Upon retiring from the Navy and NASA in 1990, Williams moved to the private sector, joining the Science Applications International Corporation. He worked there until his retirement in 2006. He died in Henderson, Nevada, on February 23, 2016, at the age of 74. His military honors included the Distinguished Flying Cross and the Legion of Merit, while his space career earned him the NASA Space Flight Medal.
