The YF-100A first flew on , seven months ahead of schedule.
It reached Mach 1.04 in spite of being fitted with a de-rated XJ57-P-7 engine.
These findings were subsequently confirmed during "Project Hot Rod" operational suitability tests.
Named Sabre 45 because of its 45° wing sweep, it represented an evolution of the F-86 Sabre.
The mockup was inspected on 7 July 1951, and after over a hundred modifications, the new aircraft was accepted as the F-100 on 30 November 1951.
This particular phenomenon (which could easily be fatal at low altitude where there was insufficient time to recover) became known as the "Sabre dance".
Nevertheless, delays in the Republic F-84F Thunderstreak program pushed the Tactical Air Command to order the raw F-100A into service.
V roce 1998 se Simon oženil s herečkou Rebeccou Rigg, se kterou má tři děti, dceru Stellu Breeze a syny Clauda Bluea a Harryho Fridaye.
Jeho dětem šly za kmotry herečky Nicole Kidman a Naomi Watts.The second prototype flew on 14 October 1953, followed by the first production F-100A on 9 October 1953.The USAF operational evaluation from November 1953 to December 1955, found the new fighter to have superior performance but declared it not ready for wide-scale deployment due to various deficiencies in the design.The aircraft could develop a sudden yaw and roll which would happen too fast for the pilot to correct and would quickly over-stress the aircraft structure to disintegration.It was under these conditions that North American's chief test pilot, George Welch, was killed while dive testing an early-production F-100A (s/n 52-5764) on 12 October 1954.Jeho velkým koníčkem je surfování a vodní pólo, v němž mnohokrát soutěžil a dosáhl významných úspěchů.
