The British organized the British Commonwealth Air Training Plan, which moved the bulk of aircrew training away from active war zones to Canada and elsewhere, where pilots started on the De Havilland Tiger Moth or Fleet Finch basic trainers before continuing on North American Harvards for advanced training, Avro Ansons, Airspeed Oxfords and Bristol Bolingbrokes for multi-engine as well as bombing training. Obsolete types such as the Fairey Battle and Westland Lysander were used for target towing, while other types such as the North American Yale were used for wireless operator (radio) training.
