About This File
FSX North American XB-70 Valkyrie. This aircraft was shaped to fly at Mach 3 remaining within its Mach cone throughout the flight regime, using the shock waves beneath the wing to generate compression lift. The wing tips could be folded down 65 degrees to increase this compression lift and also to provide greater directional stability. Unfortunately only two prototypes were built and despite their exceptional performance, the XB-70 program was cancelled after 130 missions, when an F-104 collided and destroyed the second prototype during a photo shoot. Even so, the XB70 provided invaluable high-speed flight test data. This model includes a detailed virtual cockpit with lighted gauges, folding wing tips and variable nose cone, complex movement for gear retraction, and reflective textures. Gauges and sounds are included. By Massimo Altieri.
