The McDonnell F-101 Voodoo (nicknamed One-oh-Wonder") first flew in September 1954 with the first production F-101A making its first operational flight in May 1957. In September 1957 the F-101C became operational followed by the F-101B in January 1959. When production ended 807 Voodoos had been created, 480 of them were the two-seat all-weather interceptor F-101Bs. The RF-101 reconnaissance version was the world’s first supersonic photo-recon aircraft. The only major foreign operator of the Voodoo was the Royal Canadian Air Force (RCAF) that acquired 56 CF-101B and 10 CF-101F.
