After the war Anderson became a well regarded fighter test pilot, and a fighter squadron and wing commander. He served his wing commander tour in combat in the Vietnam War. He retired as a full colonel in 1972, after which he worked in flight test management for McDonnell Douglas. A member of the National Aviation Hall of Fame, Col.
