On display at the Planes of Fame Air Museum. This is a combat veteran that served with the U.S. Navy at NAS Dunkerque, France in 1918, flying coastal patrols and searching for U-boats. Originally built as a HD.2 seaplane, it was later converted to a HD.1 land fighter. In 1923, French ace Charles Nungesser restored and flew this aircraft. It bears his famous "Knight of Death" insignia on the side of the fuselage. Most of the French-built HD.1s served with the Belgians and Italians during World War I.
