The SR-71B Blackbird, flown by the Dryden Flight Research Center as NASA 831, slices across the snow-covered southern Sierra Nevada Mountains of California after being refueled by an Air Force tanker during a 1994 flight. SR-71B was the trainer version of the SR-71. Notice the dual cockpit to allow the instructor to fly the airplane.
