The first XB-70 carried out its maiden flight in September 1964 and many more test flights followed. [71] The data from the XB-70 test flights and aerospace materials development were used in the later B-1 bomber program, the American supersonic transport (SST) program, and via espionage, the Soviet Union's Tupolev Tu-144 SST program. [72]
It was the XB-70 Valkyrie, an experimental plane developed for the US Air Force. Its inaugural flight — 60 years ago in September 1964 — kicked off a golden era for supersonic aircraft. The ...
North American Aviation (NAA) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included the T-6 Texan trainer, the P-51 Mustang fighter, the B-25 Mitchell bomber, the F-86 Sabre jet fighter, the X-15 rocket plane, the XB-70 bomber, the B-1 Lancer, the Apollo command and service module, the second stage of the Saturn V ...
The XB-70 had folding wingtips to enhance both compression lift and directional stability at high speeds. Rear view of the F-14 Tomcat showing the area between the engine nacelles. The area referred as the "pancake" provided compression lift in flight.
The program ended early due to financial and technical difficulties. In 1961, he was selected as chief test pilot for the flight test program of the XB-70 Valkyrie, the world's largest supersonic aircraft, piloting the first flights of both XB-70s and taking the aircraft through the buildup programs to flight at Mach 3.

The Mach 3 XB-70's two crew escape capsules did not work well the only time they were needed. On June 8, 1966, XB-70 airframe AV/2 was involved in a mid-air crash with an F-104 Starfighter. Maj. Carl Cross's seat was unable to retract backwards into the escape capsule due to high-g-forces as the plane spiraled downwards. He died in the crash. Maj.
Walker was killed on June 8, 1966, when his F-104N Starfighter chase aircraft collided with a North American XB-70 Valkyrie. [13] At an altitude of about 25,000 ft (7.6 km) [ 14 ] Walker's Starfighter was one of five aircraft in a tight group formation for a General Electric publicity photo when his F-104 drifted into contact with the XB-70's ...
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle.
