I'm not sure I understand how the FO let this information out. I had a captain that was always asleep 30 minutes after departure on the first flight in California. The flight was only one hour but that is what he normally did. We would change the heading bug to keep us on course until he woke up again. That was before the magenta line days. One FO was going to turn him in but was told, would you rather him fall asleep enroute or on the approach if you didn't let him sleep?
