In the USAF, anyone who has anything to do with nukes: pilots, navigators, load masters, security forces, ordinance guys, get every 6 month reviews of health, mental status, finances, performance reports. Anything out of the ordinary gets investigated.
Wouldn't the public love those protocols mandated for pilots.
Anecdotal evidence points towards depression becoming a serious issue in HKG and it's being hidden for obvious reasons. I don't think pilot management have much of a clue and they'd be well served working hard with unions on successful peer support models.
