Well life goes on for everyone. Things happen. It can be a fine line between outing a loved one thus ruining their career over nothing and doing the right thing. So if a pilot friend going through a divorce says he is depressed and wants to kill her, do pick up the phone and call the FAA knowing he has been a rock solid pilot for 2 or 3 decades?
People say a whole lot of things they don't mean and almost always it's nothing. Everyone needs confidants. Pilots are human, it doesn't mean they have any intentions other than complete commitment and dedication to the wellbeing of their passengers. Creating a situation for pilots in which they are unable to intrust anybody with the inevitabilities of life isn't the answer.
