Bermuda Triangle (History and Kusche's Explanation)

According to the Triangle authors, Christopher Columbus was the first person to document something strange in the Triangle, reporting that he and his crew observed "strange dancing lights on the horizon", flames in the sky, and at another point he wrote in his log about bizarre compass bearings in the area. From his log book, dated October 11, 1492 he wrote:

The land was first seen by a sailor (Rodrigo de Triana), although the Admiral at ten o'clock that evening standing on the quarter-deck saw a light, but so small a body that he could not affirm it to be land; calling to Pero Gutierrez, groom of the King's wardrobe, he told him he saw a light, and bid him look that way, which he did and saw it; he did the same to Rodrigo Sanchez of Segovia, whom the King and Queen had sent with the squadron as comptroller, but he was unable to see it from his situation. The Admiral again perceived it once or twice, appearing like the light of a wax candle moving up and down, which some thought an indication of land. But the Admiral held it for certain that land was near...

Modern scholars checking the original log books have surmised that the lights he saw were the cooking fires of Taino natives in their canoes or on the beach; the compass problems were the result of a false reading based on the movement of a star.
The first article of any kind in which the legend of the Triangle began appeared in newspapers by E.V.W. Jones on September 16, 1950, through the Associated Press.
Two years later, Fate magazine published "Sea Mystery At Our Back Door", a short article by George X. Sand in the October 1952 issue covering the loss of several planes and ships, including the loss of Flight 19, a group of five U.S. Navy TBM Avenger 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 in the April 1962 issue of American Legion Magazine.
The article was titled "The Lost Patrol", by Allen W. Eckert, and in his story it was claimed 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." It was also claimed that officials at the Navy board of inquiry stated that the planes "flew off to Mars." "The Lost Patrol" was the first to connect the supernatural to Flight 19, but it would take another author, Vincent Gaddis, writing in the February 1964 Argosy Magazine to take Flight 19 together with other mysterious disappearances and place it under the umbrella of a new catchy name: "The Deadly Bermuda Triangle"; he would build on that article with a more detailed book, Invisible Horizons, the next year. Others would follow with their own works: John Wallace Spencer (Limbo of the Lost,1969); 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.

Kusche's Explanation

Lawrence David Kusche, a research librarian from Arizona State University and author of The Bermuda Triangle Mystery: Solved (1975) has challenged this trend. Kusche's research revealed a number of inaccuracies and inconsistencies between Berlitz's accounts and statements from eyewitnesses, participants, and others involved in the initial incidents. He noted cases where pertinent information went unreported, such as the disappearance of round-the-world yachtsman Donald Crowhurst, which Berlitz had presented as a mystery, despite clear evidence to the contrary.
Another example was the ore-carrier Berlitz recounted as lost without trace three days out of an Atlantic port when it had been lost three days out of a port with the same name in the Pacific Ocean. Kusche also argued that a large percentage of the incidents which have sparked the Triangle's mysterious influence actually occurred well outside it. Often his research was surprisingly simple: he would go over period newspapers and see items like weather reports that were never mentioned in the stories.
Kusche came to several conclusions:

The number of ships and aircraft reported missing in the area was not significantly greater, proportionally speaking, than in any other part of the ocean.In an area frequented by tropical storms, the number of disappearances that did occur were, for the most part, neither disproportionate, unlikely, nor mysterious; furthermore, Berlitz and other writers would often fail to mention such storms. The numbers themselves had been exaggerated by sloppy research. A boat listed as missing would be reported, but its eventual (if belated) return to port may not be reported. Some disappearances had in fact, never happened. One plane crash was said to have taken place in 1937 off Daytona Beach, Florida, in front of hundreds of witnesses; a check of the local papers revealed nothing.

Kusche concluded that:

The Legend of the Bermuda Triangle is a manufactured mystery ... perpetuated by writers who either purposely or unknowingly made use of misconceptions, faulty reasoning, and sensationalism.
