The Bermuda Triangle (also known as Devil's Triangle) is a nearly half-million square-mile (1.2 million km2) area of ocean roughly defined by Bermuda, Puerto Rico, and the southernmost tip of Florida. The Bermuda Triangle has become popular through representation by the mass media, in which it is a paranormal site in which the known laws of physics are either violated, altered, or both.

While there is a common belief that a number of ships and airplanes have disappeared under highly unusual circumstances in this region, the United States Coast Guard and others disagree with that assessment, citing statistics demonstrating that the number of incidents involving lost ships and aircraft is no larger than that of any other heavily traveled region of the world. Many of the alleged mysteries have proven not so mysterious or unusual upon close examination, with inaccuracies and misinformation about the cases often circulating and recirculating over the decades.

The triangle is an arbitrary shape, crudely marking out a corridor of the Atlantic, stretching northward from the West Indies, along the North American seaboard, as far as the Carolinas. In the Age of Sail, ships returning to Europe from parts south would sail north to the Carolinas, then turn east for Europe, taking advantage of the prevailing wind direction across the North Atlantic. Even with the development of steam and internal-combustion engines, a great deal more shipping traffic was (and still is) found nearer the US coastline than towards the empty centre of the Atlantic. The Triangle also loosely conforms with the course of the Gulf Stream as it leaves the West Indies, and has always been an area of volatile weather. The combination of distinctly heavy maritime traffic and tempestuous weather meant that a certain, also distinctly large, number of vessels would founder in storms. Given the historical limitations of communications technology, most of those ships that sank without survivors would disappear without a trace. The advent of wireless communications, radar, and satellite navigation meant that the unexplained disappearances largely ceased at some point in the 20th Century. The occasional vessel still sinks, but rarely without a trace. It should be noted that both the concept and the name of the Bermuda Triangle date only to the 1960s, and were the products of an American journalist.

Other areas often purported to possess unusual characteristics are the Devil's Sea, located near Japan, and the Marysburgh Vortex or the Great Lakes Triangle, located in eastern Lake Ontario.

First citations

The first mention of disappearances in the area was made in 1950 by E.V.W. Jones as a sidebar on the Associated Press wire service regarding recent ship losses. Jones' article notes the "mysterious disappearances" of ships, airplanes and small boats in the region, and ascribes it the name "The Devil's Triangle". It was next mentioned in 1952 in a Fate Magazine article by George X. Sand, who outlined several "strange marine disappearances". The term "Bermuda Triangle" was popularized by Vincent Gaddis in a 1964 Argosy feature.

The area achieved its current fame largely through the efforts of Charles Berlitz in his 1974 book The Bermuda Triangle (right) and its subsequent film adaptation. The book recounts a long series of mysterious disappearances of ships and aircraft, in particular the December 1945 loss of five U.S. Navy Avenger torpedo bombers in the infamous Flight 19 incident. SHAZAM!

The book was a bestseller and included several theories about the cause of the disappearances, including accidents due to high traffic volumes; natural storms; "temporal holes"; the lost empire of Atlantis; transportation by extraterrestrial technology; and other natural or supernatural causes.

Skeptical responses for you to le chew on

The marine insurer Lloyd's of London has determined the "triangle" to be no more dangerous than any other area of ocean, and does not charge unusual rates for passage through the region. Coast Guard records confirm their conclusion.

Skeptics comment that the disappearance of a train between two stops would be more convincing evidence of paranormal activity, and the fact that such things do not occur suggests that paranormal explanations are not needed for the disappearance of ships and airplanes in the far less predictable open ocean.

Intrigued by the number of students coming to him looking for information about the Bermuda Triangle, Lawrence Kusche, a reference librarian with Arizona State University at the time of the Flight 19 incident, began an exhaustive follow-up investigation of the original reports. His findings were eventually published in 1975 as The Bermuda Triangle Mystery: Solved.

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 that Crowhurst had fabricated the accounts of his voyage and had probably committed suicide. 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 attributed to the Bermuda Triangle's mysterious influence actually occurred well outside it.

Kusche came to several conclusions:
The number of ships and airplanes reported missing in the area was not significantly greater, proportionally speaking, than any other part of the ocean.
In an area frequented by tropical storms, the number of disappearances that did occur was neither disproportionate, unlikely, nor mysterious.
The numbers themselves had been exaggerated by sloppy research. A boat listed as missing would be reported, but not necessarily its eventual, if belated, return to port.
The circumstances of confirmed disappearances were frequently misreported in Berlitz's accounts. The numbers of ships disappearing in supposedly calm weather, for instance, did not tally with weather reports published at the time.
