Dornier Do29 V1 YA+101 German Air Force
The Do-29 was an experimental aircraft to test a new V/STOL concept. The 2 engines were equipped with a pusher propeller which could be rotated by degrees. The concept proved successful with minimal speeds of under 75 km/h and take-off rolls of merely 80 m but the aircraft never went into production. | Ruud Boots
