Design and development
The Messenger was designed to meet a British Army requirement for a robust, slow speed, low maintenance air observation post and liaison aircraft. The aircraft designed was a cantilever low-wing monoplane with a fixed tailwheel, powered by the de Havilland Gipsy Major 1D inline engine. Fitted with retractable auxiliary wing flaps enabling a wing loading of around 12.5 lb per square foot, the Messenger featured triple fins and rudders in order to maintain sufficient controllability down to the very low stalling speed of 25 mph. The prototype was converted from a Miles M.28 Mercury and first flew at Woodley on 12 September 1942. The aircraft had good short field performance. However the Ministry of Aircraft Production had not been involved in the process and official resistance led to only a small order placed by the British Royal Air Force for the Messenger I as a VIP transport plane.
Production and operations
After the war the Messenger 2A was built for the civilian market. The production aircraft were built at Newtownards in Northern Ireland and flown to Woodley for final fitting out. After 71 aircraft were built, production of the aircraft by Miles ceased in 1948. Several examples of the type were sold to Australia and others were exported to Argentina, Belgium, Chile, Egypt, Iran, New Zealand, South Africa and Switzerland.
During the war a prototype aircraft was built as the M.48 Messenger 3 with fully retractable electrically-operated split trailing-edge flaps and a 155 h.p. Cirrus Major III engine. This model was not further developed as it did not provide any advantage over the other variants.
When the RAF retired surviving Messenger 1 aircraft in 1948 they were in good condition and most were converted for civilian use as the Messenger 4A. They were flown by private pilots and business owners.
Several examples were still flying in the United Kingdom and New Zealand in early 2011 with private owners and flying groups.
