The Bermuda Triangle is a stretch of the Atlantic Ocean bordered by a line from Florida to the islands of Bermuda, to Puerto Rico and then back to Florida. It is one of the biggest mysteries of our time - that isn't really a mystery.
The term "Bermuda Triangle" was first used in an article written by Vincent H. Gaddis for Argosy magazine in 1964. In the article Gaddis claimed that in this strange sea a number of ships and planes had disappeared without explanation. Gaddis wasn't the first one to come to this conclusion, either. As early as 1952 George X. Sands, in a report in Fate magazine, noted what seemed like an unusually large number of strange accidents in that region.
In 1969 John Wallace Spencer wrote a book called Limbo of the Lost specifically about the triangle and, two years later, a feature documentary on the subject, The Devil's Triangle, was released. These, along with the bestseller The Bermuda Triangle, published in 1974, permanently registered the legend of the "Hoodoo Sea" within popular culture.
Several books suggested that the disappearances were due to an intelligent, technologically advanced race living in space or under the sea.
The only problem was that the mystery was more hype than reality. In 1975 a librarian at Arizona State University, named Larry Kusche, decided to investigate the claims made by these articles and books. What he found he published in his own book entitled The Bermuda Triangle Mystery-Solved. Kusche had carefully dug into records other writers had neglected. He found that many of the strange accidents were not so strange after all. Often a triangle writer had noted a ship or plane had disappeared in "calms seas" when the record showed a raging storm had been in progress. Others said ships had "mysteriously vanished" when their remains had actually been found and the cause of their sinking explained.
More significantly a check of Lloyd's of London's accident records by the editor of Fate in 1975 showed that the triangle was a no more dangerous part of the ocean than any other. U.S. Coast Guard records confirmed this and since that time no good arguments have ever been made to refute those statistics. So the Bermuda Triangle mystery disappeared, in the same way many of its supposed victims had vanished.
Even though the Bermuda Triangle isn't a true mystery, this region of the sea certainly has had its share of marine tragedy. Perhaps the best known one was the story of Flight 19.
