I remember watching a RAF instructional film at around 1967. The opening scene was a twin engined aircraft, Hudson or similar, diving out of cloud. It was overstressed on the pull out and the port wing broke off. One roll before the pilot stopped it, presumably with the starboard airleron, and it continued its sixty degree dive with ninety degrees of bank on until it disappeared behind a hangar and crashed. Undoubtably all on board were killed but we young pilots all cheered.
