The Bermuda Triangle, also known as the Devil's Triangle, is a region of the northwestern Atlantic Ocean in which a number of aircraft and surface vessels have disappeared. Some people have claimed that these disappearances fall beyond the boundaries of human error or acts of nature.

The Legend of the Bermuda Triangle is surely  a manufactured mystery ...
