About William H. Dana
William Harvey Dana was an American aeronautical engineer, U.S. Air Force pilot, NASA test pilot, and astronaut. He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the Air Force and NASA. He was also selected for participation in the X-20 Dyna-Soar program. Following this in 2005, NASA retroactively awarded its civilian astronaut wings to Dana (then living), and to McKay and Walker (posthumously). Of these pilots, five were active-duty Air Force personnel who were awarded military astronaut wings contemporaneously with their achievements.
