Operational History
The first F-107A (s/n 55-5118) with North American's chief test pilot Bob Baker at the controls, made its initial flight on 10 September 1956, attaining Mach 1.03. Although successfully carrying out its flight, the brake chute did not deploy, which resulted in a "hot" landing with the nose gear strut breaking. The aircraft first achieved Mach 2 in tests on 3 November 1956. It was joined by the second F-107A (s/n 55-5119), which made its first flight was on 28 November 1956. It was used for weapons testing with both conventional and atomic bombs. The last prototype, (s/n 55-5120) had its maiden flight on 10 December 1956. At the conclusion of the F-107A's successful test program, the Tactical Air Command decided to hold a fly-off competition between the F-107A and the Republic F-105 which was designed to same mission requirements and used the same engine. Although the competition was close, the F-105 was selected as the new standard TAC tactical fighter. The three F-107A prototypes were relegated to test flying while the pre-production order was cancelled.
In late 1957, prototypes #1 and #3 were leased to the National Advisory Committee for Aeronautics (NACA) for high-speed flight research, while aircraft #2 was flown on 25 November 1957 to the National Museum of the United States Air Force near Dayton, Ohio. In September 1959, with Scott Crossfield at the controls, aircraft #3 was damaged during an aborted takeoff. The aircraft was not repaired and, ultimately, it was used for fire fighting training and was destroyed in the early 1960s.

Famous quotes containing the word history:
“When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?”
—David Hume (1711–1776)
