The legend of Santiago Flight 513 tells of a passenger plane that allegedly vanished in 1954 and mysteriously landed in Brazil 35 years later with 92 skeletons aboard. The chilling story has fueled theories about time travel, mysterious vortices, and the Bermuda Triangle. However, no credible aviation records or official investigations confirm the flight ever existed. First popularized through sensational tabloid storytelling, it remains an enduring internet legend rather than a documented aviation mystery.
