Product Information

The North American Aviation XB-70 (62-0001) is in a level cruise flight mode at a relative high altitude judging from the darkness of the sky. The XB-70A, capable of flying three times the speed of sound, was the world's largest experimental aircraft in the 1960s. Two XB-70A aircraft were built. Ship #1 was flown by the NASA Flight Research Center (now NASA Dryden), Edwards, California, in a high speed research program.

The XB-70A Valkyrie experimental aircraft measuring 190 feet in length, with a wing span of 105 feet and standing 33 feet in height. The aircraft had a delta wing and hinged wing tip that could be folded down to a 65 degree angle to improve stability at the aircraft's supersonic speeds of up to Mach 3. At this speed the Valkyrie was designed to ride its own shock wave.
