Narrative:
The Helmy Aerogypt was a British four-seat cabin monoplane designed and built by Egyptian Saleh Helmy at Heston Aerodrome in 1938. The Aerogypt I was a low-wing cantilever monoplane initially powered by three 22 hp (16 kW) Douglas Sprite engines. The aircraft had an upward hinged roof that acted as a landing flap. Registered G-AFFG, [C of R 8355] on 17.2.38, to Miss Dorothy Francis Arkell, Woodley Aerodrome, Woodley, Reading, Berkshire. G-AFFG first flew in 1939. It later had the hinged roof removed, and was re-designated the Aerogypt II.

Another modification added end plates to the horizontal tail surfaces, and was re-designated the Aerogypt III, and last flown in that configuration in September 1940.

In 1943, the aircraft was modified as the Aerogypt IV with a tricycle landing gear and two 65 hp (48 kW) Continental A65 engines. Sold on and re-registered on 7.2.45 [C of R 8355/2] to Aerogypt High Speed Development Co Ltd., London SW.1, it was flown from White Waltham Airfield.

Written off 26.11.46: damaged beyond repair when it was dropped by the recovery crane following a landing accident at RAF Northolt, Middlesex. Registration G-AFFG formally cancelled by the Air Ministry 31.1.50 as "Withdrawn". It is reported (see link #8) that the fuselage was used as a hen house in the White Waltham area until well into the 1960s!
