The USA has produced a string of experimental aircraft that have tested the furthest limits of aerospace technology. XB-70 Valkyrie is one of these fascinating aircraft. Development of the XB-70 by the North American Aviation commenced in the late 1950s, and it was a prototype of the B-70 deep-penetration bomber that was supposed to enter the ranks of the US Air Force. The six-engine aircraft was to fly at mach 3+ speeds armed with nuclear bombs at a maximum ceiling of 21,000m to avoid interceptors. Interestingly, as advanced as the Valkyrie's technology was, the introduction of high-altitide surface-to-air missles (SAM) and intercontinental ballistic missles (ICBM) made the need for the B-70 redundant and the program was cancelled in 1961. Nevertheless, two XB-70A aircraft were built and flew in a battery of supersonic test flights from September 1964 through to August 1969, although one was lost in a midair collision. They contributed to the study of aerodynamics and propulsion of supersonic aircraft.
