While we make fun of the subject, we do realize that this is serious business. Yet, we’re not in the “serious business” business, LOL.
As pilot, your career is pretty much over if you get popped for a DUI and they do have random checks at the gate for airline pilots. There seems to be some sort of a pattern of pilots bound for the US get popped and arrested in Scotland before they take off on their flight. Google it. It happened more than once during the last couple of years. Must be the whiskey there or something.
On a lighter note, though, because of these issues, there are many rules charter and airline operators have to follow. They include a “random drug and alcohol test” program. The funny part about this is, these rules do not exclude single pilot operators. I know a guy, who is pretty much a one-man show and he told me how hilarious it was to deal with the FAA trying to set up his single pilot operator drug test program. What came out of the whole thing was that essentially, he had to find a way to surprise himself with a random drug test. I thought that was really funny …
