The Bermuda Triangle is an area in the Atlantic Ocean bounded roughly at its points by Miami, Bermuda, and Puerto Rico. Legend has it that many ships and planes have mysteriously vanished in this area. But there are some skeptics who argue that the facts do not support the legend. The number of wrecks in this area is not extraordinary, given its size, location and the amount of traffic it receives. Many of the ships and planes that have been identified as having disappeared mysteriously in the Bermuda Triangle were not even in that area. The real mystery, they argue, is how the Bermuda Triangle became a mystery at all.
