Early type of helicopter being tested at airfield in Washington DC.
Title reads: "Self Catapulting Autogyro".
New Pitcairn PA-36 Whirl Wing autogyro (auto-gyro) in Washington DC, United States of America (USA).
Various shots of new type of autogyro going test flight from Bolling Field. The machine takes off and lands almost vertically. Looks very similar to modern helicopters.
