FSX NASA XB-70 Valkyrie Package. Upgraded for FSX. Go to the Space ! 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° 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 had been cancelled after 130 missions, when an F-104 collided and destroyed the second prototype during a photo shoot. Even so, the B-70 provided invaluable high-speed flight test data. This model includes a detailed virtual cockpit. Gauges and sounds are included in package. Author : Massimo Altieri.
