On Hastings nearly everyone smoked as has previously been mentioned. We had one co-pilot Ron Nash who livened up a long night flight by crawling between the Nav and Eng's seats, unconnected the Nav's (Who was on oxygen for some reason) oxygen pipe and blowing a cloud of smoke down it. "Barny" was not impressed.
One famous engineer by the name of "Whampo" Warton who started his flying career as an LAC air gunner pre-war, preferred snuff. His favourite trick was to invite some unsuspecting young officer to partake of a pinch, knowing that the boss was looking for him for a bollocking. By the time the poor wretch had heard the summons and made the office door, he was reduced to a snivelling sneezing,red-eyed shambles.
Whampo did pay a price for this. On one occasion the co-pilot filled his snuff box with fuses making it impossible to get the fingers in and on another, John Shere simply swapped the snuff for curry powder. Whampo's sneezing and choking could be heard over the sound of the four Hercules.
