Michael James Adams was an American aviator, aeronautical engineer, and USAF 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 enlisted in the United States Air Force in 1950, and earned his pilot wings and commission in 1952 at Webb Air Force Base, Texas. He served as a fighter-bomber pilot during the Korean War, where he flew 49 combat missions. In 1958, Adams received a Bachelor of Science degree in Aeronautical Engineering from the University of Oklahoma and, after 18 months of astronautics study at Massachusetts Institute of Technology, was selected in 1962 for the U.S. Air Force Test Pilot School at Edwards Air Force Base, California. On November 15, 1967, Adams flew X-15 Flight 191. He reached a peak altitude of 266,000 feet (81 km). Moments later the craft broke apart, killing Adams and destroying the X-15-3. He was the first American space mission fatality by the American convention.
