Urinating in the aisle?? LOL!! Throw him out the airlock!
There should be something attendants should be able to do instead of divert an entire flight. I don't know. What do you think? Is there some kind of shot they can give someone to knock them out? I know that's extreme but if my flight was delayed 10 hours because of some drunk in the aisle I'd be SOOO pissed off.
