8028 Joeengle           Discovered 1991 Aug. 30 by R. H. McNaught at Siding Spring.
Air Force test pilot Joe Engle (b. 1932) was the eighth pilot to fly the X-15 and made a total of 16 flights. He received Air Force astronaut wings for a flight that took him to 85500 meters. Engle also flew the Space Shuttle, becoming the only person who reached space before being selected as an astronaut.
