At Ringway, one of the existing projects was the Hafner Rotachute, a rotor kite (unpowered autogiro) that was planned to deliver an armed soldier to a battlefield more accurately and reliably than conventional parachute methods.
[1][2] Manned trials of the Rotachute began in early 1942, towed firstly behind ground vehicles, then behind aircraft.
Those included examples of Bombay, Dakota, Halifax, Hector, Heyford, Hudson, Lysander, Manchester, Martinet, Master, Mitchell, Mosquito, Overstrand, Spitfire, Stirling, Tiger Moth, Warwick, Wellington, Whitley, Wildcat.
AFEE also conducted testing of captured rotary wing aircraft, such as examples of the Focke-Achgelis Fa 330 'kite' autogiro.
Additional support aircraft included Boston, Cierva C.40, Curtiss Commando, Dragonfly, Harvard, Hastings, Lancaster, Valetta.
[4] On 14 September 1950, AFEE was disbanded, and most of its equipment and personnel were transferred to the Aeroplane and Armament Experimental Establishment at RAF Boscombe Down.
