Logged many hours sawing logs in the Herky Hilton. Not sure about doing it up top tho. Funny story about sleep on the herc... Bob McDonald, 17th TAS DOV F/E Examiner ("Bobby Beback", nickname earned after telling his wife he'd be back after fetching a loaf of bread, not to return for two days, so many bars on the Parks highway in Alaska!, but this is another story...) A smart Flight Engineer always does his homework before a checkride, of course, with Bobby if you turned up the heat in the cockpit and happened to have a Playboy magazine in your book bag, Bobby would be out like a light for the duration of the checkride and you would get a Q1. This is not to say Bob wasn't a "walk on water" flight examiner, he was. And if you didn't know your stuff he would break it off in your ass so this tactic only worked on squared away F/Es.
