I think you will find most ' lost plane parts on other airplane' stories are apocryphal, with or without Ernie Borgnine playing a ghost smelling of Bay Rum. In WW2 a Blimp crashed ashore here in Southern California without it's crew.The best explanation ( after the usual UFO had their say later)is one crewman was leaning out to make an emergency repair, got in trouble and when his crewmate tried to help both fell to their death. I got to ride one of the Goodyear advertising blimps years ago. In fact, San Pedro even in the mid 1950s was still scene for the last blimp operations and much of the equipment went into Goodyear's fleet- including the gondola from that crashed blimp I was later to ride in.
