Background
In the decade following the end of World War II, aircraft performance and design advanced at a dizzying pace. Proposed in 1951 and first flown in 1953, the North American F-100 Super Sabre followed in the footsteps of legendary P-51 Mustang and F-86 Sabre, and was the first American production fighter capable of flying at sustained supersonic speeds in level flight. Although intended as a clear-weather daytime air superiority fighter, the “Hun” saw its most notable service during the Vietnam War as a fighter-bomber. The quantum leap in performance over previous fighters was accompanied by an unprecedented accident rate, as Air Force pilots with supersonic experience were few and far between outside of the flight test community. In order to curb the high accident rate, North American developed a two-seat trainer variant on its own nickel, and the design rapidly evolved into a two-seat variant of the F-100D, designated F-100F.
