Harrision, William Airspeed Oxford and Consul

With more than 8750 built the Oxford was a well thought-out design that was based on their Airspeed Envoy, a similar shaped twin-engine executive aircraft that was used in the early 1930s but the more advanced design of the Oxford suited the military requirement for a three-seat training aircraft. The Oxford was a low-wing cantilever monoplane of advanced design and was produced for the training of pilots in handling modern, multi-engine bomber aircraft.

Wooden construction was employed throughout making for a simpler design and easier repairs. Provision was made for instruction in pilot training, aerial photography, navigation, aerial photography and bombing training. An Armstrong-Whitworth gun turret could be installed for training in aerial gunnery. After the War the Consul was conceived as a small airliner, chiefly converted from ex-military Oxfords with more than 160 rebuilt. These quickly sold to potential airline operators and were eventually used in many countries, some changing hands four or five times. The Oxford and the Consul were relatively safe flying machines and with thousands of bomber pilots undertaking their flying training in the type it played a major part in the RAF's war effort, and is widely regarded as a design the manufacturers could be proud of.
