Bandleader Glenn Miller vanished over the English Channel in 1944 while flying from England to France to play for soldiers who had recently liberated Paris. His disappearance has never been explained, but here’s one possibility: In foggy conditions, Miller’s plane may have been bombed out of the air by the Canadian Air Force, which was disposing of unused bombs after an aborted attack on German positions.

“There is no rest, there must be no rest for a fellow when he is successful,” Miller once said. “He has got to keep right on going.”
