Capt Kremlin,
Re the crew goinbg to sleep, there was no such thing as fatigue management. I did three trips in an A (not asleep though) and my average crew day was 40 hours over the three trips.
My second trip was the most interesting. Lost an engine due to nacelle overheat going into Darwin. An engine change was required; but I was ordered off the airfield by Gpt capt Hitchins (an old 36 Sqn CO) and took off on three engines declaring a PAN on taxy. Got an overtemp on one of the other engines on take off but elected to keep it going. Went to Tindal after 40 hours awake. After double engine change returned to Darwin for fuel and flew to Adelaide via Tindal to pick up an orphanage and a hippie colony plus a rabbit and two puppies. total pax and crew 186 with 19 on the flight deck.
