It's considered unlucky to drink within 24 feet of an aeroplane...
or something.
Actually, for most of the history of powered flight, the measure of a Manly Man was how much booze he could take on board, and how well he concealed the effects when airborne. Drinking & flying & chasing & stuff were institutionalized to varying extents, perhaps most notably in the Luftwaffe which had vomitoria (?) at major bases.
I used to know a 190 pilot who said that Type A males judged one another by their capacity for having a Good Time. When the sun rose, they'd climb into their
maschinen, turn the oxygen regulator up to 100%, "and when you put your wheels in the well to engage 1,000
viermots, you were instantly sober!"
Now the wheel has definitely turned. A squadron CO's career can be effected if one of his pilots incurs a DUI.
