In years gone by in the Air force it was not unknown for a pilot to have a pint of beer as a "sharpener" before flight. So maybe if you have just above the legal min blood alcohol you may have reaction times that are better than if you were below the limit.
Anyway in what other walk of life do you get sent to prison and loose your right to work for 10+ years for one mister-meaner. Surely mandatory treatment and blood testing that the treatment has worked would be more humane.
But I guess reading some poster's comments they do not have any humanity. Just a hate for the profession for some reason.
