🚀 The Futuristic XB-70 Valkyrie: A Supersonic Marvel ✈️⚡ Historic roll out footage of the North American XB-70 Valkyrie. This aircraft arrived here in 1969. Originally designed in the 1950s as a high-altitude, nuclear strike bomber, the XB-70A Valkyrie was built to fly at Mach 3—three times the speed of sound!

#TBT The XB-70 Valkyrie was the largest x-plane. Capable of flight at speeds three times the speed of sound (2,000 miles per hour) and altitudes of 70,000 feet, the XB-70 was used to collect in-flight information for use in the design of future supersonic aircraft.This video shows an XB-70A taking off from Edwards Air Force Base.
