Developed from the XF-88 penetration fighter, the F-101 originally was designed as a long-range bomber escort. Before production began the design was changed to fill both tactical and air defense roles. The F-101 made its first flight on September 29, 1954. The first production F-101A became operational in May 1957. McDonnell Aircraft delivered 807 F-101s when production ended on March 1961, The multi-mission F-101 was used by all three US Air Force Commands – (Tactical, Strategic, and Air Defense) and by the Canadian Air Force. The Voodoo was the world’s first supersonic photo-recon aircraft. It was used during the Cuban Missile crisis and during the late 1960s in Southeast Asia. In Operation Firewall on December 12, 1957, an F-101A fighter-bomber, set a world speed record of 1,207 mph. In Operation Sun Run in 1957, an RF-101 raced from Los Angeles to New York and back in a record time of 6 hours and 46 minutes. The F-101B were the only model to use the J57-P-55 turbojet engines which afterburners were substantially longer than the J57-P-13 engines. The last Voodoo retired in 1986. This JF-101B Voodoo S/N 56-0250 is one of only two F-101Bs that were modified to be used in special tests for development purposes. This aircraft was last flown by the 4440th Aircraft Delivery Group at Langley AFB, VA.
