A TV documentary shown in Aus in the late 90's on the ABC, possibly a BBC or Granada production, called Aeroplanski, had numerous references to pre & inflight imbibing.
I remember seeing that, or a similar, documentary, it was shown on SATV. There was one scene which sticks in my memory, of a group of middle-aged pilots sitting at a table before flying, knocking back vodka. One said :
"No vorry for drink. Look for age of pilot, old pilot good pilot, young pilot maybe not so good. Nazhdarovya!"
