North American F-100 Super Sabre

The North American F-100 Super Sabre is an American supersonic jet fighter aircraft designed and produced by the aircraft manufacturer North American Aviation. The first of the Century Series of American jet fighters, it was the first United States Air Force (USAF) fighter capable of supersonic speed in level flight.
The F-100 was envisioned during the late 1940s as a higher-performance successor to the F-86 Sabre air-superiority fighter. Initially referred to as the Sabre 45, it was delivered as an unsolicited proposal to the USAF in January 1951, leading to two prototypes being ordered one year later following modifications. The first, YF-100A, performed its maiden flight on 25 May 1953, seven months ahead of schedule. Flight testing demonstrated both the F-100's promising performance and several deficiencies, which included its tendency of yaw instability and inertia coupling that led to numerous fatal accidents. On 27 September 1954, the F-100A officially entered USAF service, but as a result of six major accidents by 10 November 1954, the type was grounded while investigations and remedial work were conducted. The F-100 returned to flight in February 1955.
