Flight Of The Valkyrie.

The North American Aviation XB-70 Valkyrie is am immense, exotic and incredibly fast supersonic bomber. Many have never seen the Valkyrie because only two models of the prototype jet were built and used for testing. So what is the history of the XB-70, the world’s fastest supersonic bomber?

Introduced in 1964 the XB-70 was planned as a supersonic bomber as well as a research aircraft. It underwent rigorous testing over a period of five years to ensure that it was suitable for combat missions. Equipped with six engines it had no trouble hitting a top speed of Mach 3 while flying at over 70,000 feet. Those high speeds allowed it to easily outpace enemy fighters and missiles targeting it.

The development program of the XB-70 was a success but it was not without accidents. On June 8th, 1966 during a promotional photo shoot an F-104 underestimated its distance from the Valkyrie and crashed into its wing. Unfortunately, the XB-70 program was canceled in 1969 and the only remaining model remained in storage.
