Speaking as a frequent passenger, I'm deeply dismayed to learn that one of the two people on whom my life depends while in the air, may have demonstrated suicidal tendencies to the point where his airline makes him go for regular psych-checks. He shouldn't be flying my plane!
How in the name does such a person go on to achieve a commercial pilot's licence? Show him compassion, provide care and help - but don't under any circumstances give him the keys to a passenger-carrying aircraft.
