I also remember Loran, which dates me. I also remember one of my final command checks, where the F/O fell asleep on finals, after an all night freighter flight. When I spoke to him afterwards, he admitted that it was not the first time. You’re going to find this hard to believe, but he’d done it before whilst hand flying on finals. I later found out that at his previous company he’d been notorious for it. Flying for an IT company, he’d normally flown with his shoulder harness on. Otherwise he tended to bang his head on the coaming.
Having returned today, from an overnight flight from the middle of Asia, and not managing to sleep during the afternoon, I had a couple of naps on the way back. All as recommended, with the full knowledge of the F/O. Does that make me a “Gummer”, because the F/O did exactly the same in turn?
