I have definitley noticed the trend of divorce in most of the pilots I have flown with. Although I have never been married, I think the type-A personality and arrogance of us pilots is the bigger problem than the schedules when it comes to being married. Take the advice I recieved from a production test pilot at RaytheonAircraft... "you wanna be married? Just save yourself the trouble... find a girl and buy her a house."
I thought it was funny although it doesn't reflect my thoughts on marriage or that it can't work with our chosen profession. I am really looking forward to being married someday!
