Well, its not just the military which HAD a drink culture, (and I remember getting airborne in a Canberra when some muppet called a TACEVAL very late one Friday evening, the whole squadron having been in the bar since about 5pm, amazingly we all got back without breaking anything !) Moving into civil aviation I was introduced to the after landing "chocktail; turn off the runway, the purser would appear with 'Brown milks' or champers !
Just can't imagine that happening now !!
