a bristolian said most (the 762s with the 'Bristol' engines) went with a full load and cargo.
Sorry to be pedantic but none of Britannia's 767-204ER's are fitted with "Bristol" 211 engines nor do any of their 767-304ER's. They all come fitted with "Caerphilly" CF6 engines. All their 752's come with Rollers though.......
