XB-70 Valkyrie: An experimental supersonic aircraft, the XB-70 took to the skies five years before Concorde. NASA/Divds Super fast: The XB-70 was capable of flying at just over 2,000 miles per ...

The North American XB-70 Valkyrie, a Cold War-era bomber, was a technological marvel designed to fly at Mach 3 and at 70,000 feet, circumventing Soviet air defenses through speed and altitude.

The XB-70 takes off in August 1965. NASA The first XB-70 Valkyrie built, the XB-70A, had handling at speeds greater than Mach 2.5, and only got above Mach 3 once. So a ...

Photo: NASA. At first glance, the Valkyrie doesn't seem to be a plane developed in the late 1950s and early 1960s. ... Unfortunately, the XB-70 story doesn't have a happy ending.

The experimental legacy of the iconic XB-70 Valkyrie, which made its first flight on Sept. 21, 1964. ... NASA employed the XB-70 to investigate supersonic flight operations, ...

XB-70 pilot Al White was able to eject, but he sustained serious injuries. The XB-70’s co-pilot Carl Cross and NASA’s Chief Test Pilot Joe Walker (F-104 pilot) were both killed.

XB-70: Paved the Way for Supersonic Civilian Flight The XB-70 program was cancelled in 1969. However, it gave the Air Force and NASA significant data on flying such a huge airplane at high speeds ...

So, the XB-70 didn't have much future as a strategic bomber. But NASA saw the Valkyrie as a prime source of data on how materials and aircraft shapes would perform at supersonic speeds. They ...

Donald L. Mallick flew an XB-70 as a NASA test pilot after the crash and piloted a TB-58 chase plane next to the surviving jet on its last flight from Edwards Air Force Base, Calif., to the museum ...
