RAF Errol (aka Errol airfield) is a World War II airfield near the village of Errol in Perth & Kinross, Scotland, on the north bank of the Firth of Tay approximately half way between Perth and Dundee. The airfield opened in January 1943. Errol housed No. 305 Ferry Training Unit as a special air training /conversion/ unit for the Soviet crews receiving deliveries of Armstrong Whitworth Albemarles. This joint operation continued until April 1944, despite cancellation of Albemarle deliveries in September, 1943.
