Eeerrrr Roy mate, if you know your aviation history, folklore and actual practice then you would know that this was common place back then. Alcohol and drug testing was not. Management and flight crew knew who had a problem and it was delt with accordingly and discretely.
I believe that discussing the changes in the practice of identifying and dealing with any issues with flight crew is the point of this thread.
Hull loses due to intoxication at the controls of any major western European carrier - No idea 'cos I haven't heard of any.
As far as I know (which isn't far) it was management who stopped the crew bus beers, for accountancy reasons.
Once the chocks are in, engines shut down, passengers disembarked and hotel beckoning, nothing wrong with a post flight beer!
