45 Group, RAF Transport Command, Dorval, Quebec. Canadian-built Mosquito KA260 took off from Crumlin Airport, London, Ontario, for Goose Bay, Labrador, the first leg of a delivery flight from Canada to Prestwick, Scotland. En-route, the crew encountered low cloud, rain, icing, and very unusual atmospheric conditions which made wireless communication almost impossible. At about noon, the aircraft was sighted flying off course by Quebec farmer Wilfred Ross near St Irenee, some 35 miles south of Mont Joli. In heavy rain, with clouds covering the mountain tops down to 500 feet, the Mosquito circled the farm three times before flying off to the NE. Moments after disappearing from view into a valley it struck trees on the eastern slope of a heavily wooded, 1200-foot high hill, cartwheeled and disintegrated, killing both crew members
New Zealand Civilian Pilot Captain BJ Duigan and Canadian Civilian Radio Officer/Navigator JS Tegart were killed in this flying accident
