The Lancaster Bomber crews in WW2 used to play chicken with other aircraft. They would take turns in shutting down an engine to see who could maintain height on fewer engines. (I have seen photographs of a B17 on 2 engines taken from a Lanc, both props feathered on the wing shown in the photo. Apparantly, the Lanc won). During a war when chances of survival were extremely low anyway, such things didn't seem to matter! Boys 0f 20 will be boys of 20, no matter what the era.
