Bermuda Triangle

Triangle area:-In 1964,Vincent Gaddis  wrote in the pulp magazine argosy of the boundaries of the Bermuda Triangle,giving its vertices as Miami, San Juan, Puerto Rico and Bermuda. Subsequent writers did not necessarily follow this definition. Some writers gave different boundaries and vertices to the triangle, with the total area varying from 1,300,000 to 3,900,000 km² (500,000 to 1,510,000 sq mi).Consequently, the determination of which accidents occurred inside the triangle depends on which writer reported them. TheUnited States Board on Geographic Names does not recognize the Bermuda Triangle^.

Origins:- The earliest suggestion of unusual disappearances in the Bermuda area appeared in a September 17, 1950, article published in The Miami Herald(Associated Press)  by Edward Van Winkle Jones.Two years later, Fate magazine published "Sea Mystery at Our Back Door", a short article by George X. Sand covering the loss of several planes and ships, including the loss of Flight 19 , a group of five US Navy Grumman TBM Avenger torpedo bombers on a training mission. Sand's article was the first to lay out the now-familiar triangular area where the losses took place. Flight 19 alone would be covered again in the April 1962 issue of American Legion magazine. In it, author Allan W. Eckertwrote that the flight leader had been heard saying, "We are entering white water, nothing seems right. We don't know where we are, the water is green, no white." He also wrote that officials at the Navy board of inquiry stated that the planes "flew off to Mars." Sand's article was the first to suggest a supernatural element to the Flight 19 incident. In the February 1964 issue of Argosy, Vincent Gaddis' article "The Deadly Bermuda Triangle" argued that Flight 19 and other disappearances were part of a pattern of strange events in the region. The next year, Gaddis expanded this article into a book, Invisible Horizons.

Others would follow with their own works, elaborating on Gaddis' ideas: John Wallace Spencer (Limbo of the Lost, 1969, repr. 1973); Charles Berlitz (The Bermuda Triangle, 1974);Richard Winer (The Devil's Triangle, 1974),and many others, all keeping to some of the same supernatural elements outlined by Eckert.
