Lowell Ford has enjoyed a 40-year career in the aerospace industry, working at North American Aviation, Inc., Rockwell International and The Boeing Company. He also served four years in the US Navy. His interest in the Mustang grew out of the mystery of what happened to the prototype X73, and continued into a greatly expanded appreciation for the men who designed it, built it, and made it the premier fighter of World War II. He lives in the USA.
