The McDonnell Voodoo began as the XF-88 all-weather interceptor (fighter), which first flew at Muroc Dry Lake Air Base, Calif., in 1948. The two prototypes evolved into the F-101 Voodoo, a supersonic fighter designed to escort bombers and serve as a fighter bomber, an all-weather interceptor and a photoreconnaissance aircraft. In Operation Sun Run in 1957, an RF-101 raced from Los Angeles, Calif., to New York and back to Los Angeles in a record time of 6 hours 46 minutes.
