I heard a story about a bush pilot in Alaska that was hired to haul a newly-dead body from a small town to a big one, where it would be properly dealt with at a mortuary. He had removed the passenger seat to make room for the corpse. He climbed to cruising altitude and along the way encountered rough air, getting tossed around a bit. Apparently that and the decomposition gases in the corpse caused it to sit up. Pilot nearly fainted.
