Feb 28, 2014 · The XB-70 took off from Edwards and flew to Wright-Patterson Air Force Base, OH, where the aircraft was put on display at the Air Force Museum. The first XB-70 made 83 flights totaling 160 hours and 16 minutes, while the second XB-70 logged 46 flights in its brief life, totaling 92 hours and 22 minutes.

The North American Aviation XB-70 Valkyrie was the prototype version of the proposed B-70 nuclear-armed deep-penetration strategic bomber for the United States Air Force's (USAF) Strategic Air Command. Designed by North American Aviation in the late 1950s, the Valkyrie was a large six-engined...

The North American Aviation XB-70 Valkyrie is the prototype of the B-70 nuclear-armed, deep-penetration strategic bomber for the U.S. Air Force's Strategic Air Command. In the late 1950s North American Aviation designed the Valkyrie bomber as a large, six-engined aircraft capable of reaching Mach 3+ while flying at 70,000 feet ( Template ...

In flight, the XB-70 could lower the outer wing sections 25 degrees for flying from 300 knots to Mach 1.4, or a severe 65 degrees for speeds from Mach 1.4 to Mach 3+. Measuring just a bit over 20 feet at the trailing edge, these wingtips represent the …

Both the projected aircraft had a takeoff weight of around 1 million pounds (450 tonnes), and the ability to dash at Mach 3 (by jettisoning wing sections). But they were too large to fit into existing USAF hangars and other facilities, built mainly to accommodate the B-52.
