Giant wind tunnel sped aircraft innovation

National Air and Space Museum Curator John Anderson describes major flight innovations made possible by the Full Scale Tunnel, built in 1931 at the National Advisory Committee for Aeronautics Langley Memorial Laboratory in Hampton, Va. Wind flow inside the wind tunnel reached 120 miles per hour and was driven by two 7,000 pound fan blades connected to two 4,000 horse power electric motors.
