Notes: The Short Sandringham Flying Boat was a post war civil conversion of the wartime Sunderland patrol aircraft. Conversion usually involved removal of front and rear turrets and replacing them with streamlined fairings. The interiors were converted to hold up to 30 passengers, in luxury that has never been surpassed. The maiden flight of the civilian version was in 1946. 26 were built in total and remained in service up to the 1960's. Engine type / no. Prop / 4 Passengers 30 Flight crew Length 82.3 ft.
