The Dornier Do 31E3 was a German experimental jet-powered vertical take-off and landing (VTOL) aircraft designed in the 1960s. It was intended to be a transport aircraft for the NATO forces in Europe, capable of carrying up to 36 troops or 4 tons of cargo. The Do 31E3 was the third and final prototype of the Do 31 series, which featured four lift engines in the wingtips and two cruise engines in the rear fuselage.
The Do 31E3 made its first flight in July 1969 and achieved a successful transition from vertical to horizontal flight and back. However, the project was cancelled in 1970 due to technical difficulties, high costs and changing military requirements. The Do 31E3 was the only VTOL aircraft of its size and class to ever fly, and remains a remarkable achievement in aviation history.
