The Tragic Crash of the XB-70 Valkyrie
The XB-70 Valkyrie was a cutting-edge, six-engine jet bomber developed by North American Aviation in the 1950s. The aircraft was designed to fly at speeds over Mach 3 and altitudes above 70,000 feet. Despite its impressive capabilities, the XB-70 Valkyrie never entered production due to a combination of technical issues, rising development costs, and the development of intercontinental ballistic missiles (ICBMs). However, the aircraft’s tragic crash on June 8, 1966, during a test flight, shocked the aviation world and remains a topic of interest among enthusiasts today.
Airframe and Crew
The ill-fated aircraft, Air Force serial number 62-0207, was the second XB-70 built, and it first took to the skies on July 17, 1965. On the day of the crash, the crew consisted of:
- Major Carl S. Cross: Pilot and commander of the aircraft
- Alvin S. White: Co-pilot and systems operator
- Joe Walker: Civilian test pilot and observer, who was also a renowned astronaut and X-15 rocket plane pilot
Crash Details
The XB-70 Valkyrie took off from Edwards Air Force Base in California on a routine test flight, joined by an F-104 Starfighter chase plane piloted by Joe Vensel. The flight plan involved a series of high-speed maneuvers, including a pass over the airbase at an altitude of 25,000 feet. As the XB-70 approached the F-104, the aircraft’s wings began to flutter violently, causing a loss of control. Despite attempts by the crew to recover the aircraft, the XB-70 broke apart and crashed in a remote area of the Mojave Desert.
🔍 Note: An investigation into the crash revealed that the F-104's wake turbulence had caused the XB-70's wings to flutter, leading to the loss of control.
Investigation and Findings
The US Air Force conducted an extensive investigation into the crash, which concluded that the primary cause was theXB-70’s sensitivity to turbulence and the inadequate training of the crew in handling such situations. The investigation also highlighted the need for improved communication between the crew members and the importance of adhering to established flight procedures.
Aftermath and Legacy
The crash of the XB-70 Valkyrie led to significant changes in the design and testing of high-speed aircraft. The incident also spurred the development of more advanced safety features and crew training programs. Despite the tragedy, the XB-70 remains an important part of aviation history, symbolizing the innovative spirit and pioneering achievements of the 1950s and 1960s.
🤝 Note: The XB-70 Valkyrie is now on display at the National Museum of the United States Air Force in Dayton, Ohio, serving as a reminder of the aircraft's impressive capabilities and the sacrifices made by the crew.
