The Bermuda Triangle — roughly 500,000 square miles of the western Atlantic — has been connected to the disappearance of ships and aircraft for over a century.
In 1918, the USS Cyclops vanished with 309 people on board.
In 1945, five Navy aircraft known as Flight 19 disappeared during a routine training mission, followed by a rescue aircraft sent to find them.
In 1948, the passenger aircraft Star Tiger vanished without a signal.
Scientists point to the Gulf Stream, methane deposits, and rapid weather shifts as possible explanations.
But in many cases, the final moments remain missing from the record.
