Wish I could sleep for 40 mins on an aeroplane!
.. not enough exposure to back of the clock flying, that man !
My best recollection - it was of another pilot, of course, (obviously, to protect those as guilty as sin) ... he was sound asleep and well into a fine dream .... the other pair landed the bird, taxied in, parked, shut down and left. When the loaders had finished unloading they, too, locked up, shut off the power, and left .... life definitely was a bit more relaxed in years gone by.
Seriously, though, not being sensible about glucose and sleep patterns is the height of stupidity, especially if operating single pilot.
