Footage of the 6-engined XB-70 Valkyrie, a 1960s coldwar supersonic strategic nuclear bomber.
Built by North American as a nuclear bomber for the U. S. Air Force\\\'s Strategic Air Command in the 1950s, it is a large, high-altitude bomber with six engines that can fly at over Mach 3. Only two prototypes were ever built and the only one now in existence is at Wright Patterson AFB.
It was designed to deliver very high-yield nuclear weapons and carry them at supersonic speeds during the entire mission. A high speed, high-altitude capability was needed for this. It actually uses its own sonic boom to power its flight. Its design included a long fuselage and delta wing configuration, also used by the SR-71 and the Concorde. It was built of stainless steel, titanium, and used honeycomb panels.
Features footage of it\\\'s maiden flight, wheel lockup and flameout, and it\\\'s infamous collision with an F-104 in 1966.
