Throughout history, there have been hundreds of events and phenomena that just can't be explained. From Area 51 to vanishing planes, these are the most mysterious occurrences in history...
Over the course of half a century, airplanes and ships have vanished inside a triangular portion of the North Atlantic Ocean known as the Bermuda Triangle. In 1964, Vincent Gaddis wrote "The Deadly Bermuda Triangle," which asserted that the disappearances were all strangely connected to the region.
The first known instance of a ship disappearing in the area was the USS Cyclops in 1918. After departing the island of Barbados, the ship and its crew of 309 vanished without a trace. Those who believe in the legend of the Bermuda Triangle stand by a number of theories, including extraterrestrial activity and paranormal explanations.
