I do if they have intentions of killing themselves. Personally, I wouldn't want my family flying on a plane if I knew that one of the pilots has suicidal tendencies. Although I'm sympathetic to people with these problems, they aren't always in a state to make rational decisions. I know because my step-son suffers from these problems.
How would you feel if you knew that one of your pilots is having a particularly bad day and is going to fly in about an hour? Would you or your family get on the plane? Heck, I've flown with people going through nasty divorces who had to be taken off the line. It's nothing personal, but if you're not in the state of mind to act like a professional, you don't belong up there. Jmho.
WADR, I think you and ALBIE are missing the point. In perfect world of kittens and no mean people, it would be great to ground folks with any tendancies we don't like. Unfortunately, we don't live there. Albie talks of the PRP program in the AF. Since they have it all figured out, I'm sure no one in the program ever killed themselves....WRONG.
THESE RULES HAVE THE OPPOSITE EFFECT!!. Granted, if someone is merely nucking futz, it's noticed and he's grounded. The problem is those on the edge or progressing there. THEY WILL NOT SEEK HELP. If someone is going thru a bad divorce, do you want them in the cockpit "untreated"?
In this case, Capt Zenner was NOT a danger to others. He could have gone out on his finni flight in the 400 and killed a lot of people. He wanted to commit suicide, not murder.
I don't want my family flying on a plane with a pilot who has suicidal tendancies either. That's why I want anyone with those tendancies to BE TREATED!! Your solution is to say it's OK for them to fly your family if merely HIDE that tendancy.
