I suppose most have heard about the B-24 “Lady Be Good” that crashed in the Libyan desert on its return from a bombing mission over Italy. It wasn’t discovered until 1958. It was the crew’s first mission and no bodies were found. Seems that everyone at the base in Libya assumed it had gone down in the Mediterranean, so they didn’t look for it on land. I remember that Rod Serling made an episode of “The Twilight Zone” about it back in the early 60s.
