The sadly late-lamented TriStar had a few tales.... One common theme was the ghost of "flight 401", the servicable L1011 that the crew allowed to descend into the ground!
Popular TriStar folklore had various tales of hauntings. I have never seen a ghost but, I have felt uncomfortable in situations . We often flew the RAF TriStar with just 4 crew, Capt, Co, Eng and Loady. It was certainly spooky if you went right down the back to the loo or galley with the other 3 on the flightdeck , esp, at night, 40,000' over...nowhere.
