The Bermuda Triangle, also known as the Devil’s Triangle, is a loosely-defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. Most reputable sources dismiss the idea that there is any mystery. The vicinity of the Bermuda Triangle is one of the most heavily traveled shipping lanes in the world, with ships frequently crossing through it for ports in the Americas, Europe, and the Caribbean islands. Cruise ships and pleasure craft regularly sail through the region, and commercial and private aircraft routinely fly over it.
Popular culture has attributed various disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors.
In 1964, Vincent Gaddis wrote in the pulp magazine Argosy of the boundaries of the Bermuda Triangle: three vertices, in Miami, Florida peninsula, in San Juan, Puerto Rico, and in the mid-Atlantic island of 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. The United States Board on Geographic Names does not recognize the Bermuda Triangle.
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 U.S. 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. Eckert wrote 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.
Persons accepting the Bermuda Triangle as a real phenomenon have offered a number of explanatory approaches.
Triangle writers have used a number of supernatural concepts to explain the events. One explanation pins the blame on leftover technology from the mythical lost continent of Atlantis. Sometimes connected to the Atlantis story is the submerged rock formation known as the Bimini Road off the island of Bimini in the Bahamas, which is in the Triangle by some definitions. Followers of the purported psychic Edgar Cayce take his prediction that evidence of Atlantis would be found in 1968 as referring to the discovery of the Bimini Road. Believers describe the formation as a road, wall, or other structure, but the Bimini Road is of natural origin.
Other writers attribute the events to UFOs. This idea was used by Steven Spielberg for his science fiction film Close Encounters of the Third Kind, which features the lost Flight 19 aircrews as alien abductees.
Charles Berlitz, author of various books on anomalous phenomena, lists several theories attributing the losses in the Triangle to anomalous or unexplained forces.
Compass problems are one of the cited phrases in many Triangle incidents. While some have theorized that unusual local magnetic anomalies may exist in the area, such anomalies have not been found. Compasses have natural magnetic variations in relation to the magnetic poles, a fact which navigators have known for centuries. Magnetic (compass) north and geographic (true) north are only exactly the same for a small number of places – for example, as of 2000, in the United States, only those places on a line running from Wisconsin to the Gulf of Mexico. But the public may not be as informed, and think there is something mysterious about a compass “changing” across an area as large as the Triangle, which it naturally will.
The Gulf Stream is a major surface current, primarily driven by thermohaline circulation that originates in the Gulf of Mexico and then flows through the Straits of Florida into the North Atlantic. In essence, it is a river within an ocean, and, like a river, it can and does carry floating objects. It has a surface velocity of up to about 2.5 metres per second (5.6 mi/h). A small plane making a water landing or a boat having engine trouble can be carried away from its reported position by the current.
One of the most cited explanations in official inquiries as to the loss of any aircraft or vessel is human error. Human stubbornness may have caused businessman Harvey Conover to lose his sailing yacht, the Revonoc, as he sailed into the teeth of a storm south of Florida on January 1, 1958.
Tropical cyclones are powerful storms, which form in tropical waters and have historically cost thousands of lives lost and caused billions of dollars in damage. The sinking of Francisco de Bobadilla’s Spanish fleet in 1502 was the first recorded instance of a destructive hurricane. These storms have in the past caused a number of incidents related to the Triangle.
A powerful downdraft of cold air was suspected to be a cause in the sinking of the Pride of Baltimore on May 14, 1986. The crew of the sunken vessel noted the wind suddenly shifted and increased velocity from 32 km/h (20 mph) to 97–145 km/h (60–90 mph). A National Hurricane Center satellite specialist, James Lushine, stated “during very unstable weather conditions the downburst of cold air from aloft can hit the surface like a bomb, exploding outward like a giant squall line of wind and water.” A similar event occurred to the Concordia in 2010 off the coast of Brazil. Scientists are currently investigating whether “hexagonal” clouds may be the source of these up-to-170 mph “air bombs”.
An explanation for some of the disappearances has focused on the presence of large fields of methane hydrates (a form of natural gas) on the continental shelves. Laboratory experiments carried out in Australia have proven that bubbles can, indeed, sink a scale model ship by decreasing the density of the water; any wreckage consequently rising to the surface would be rapidly dispersed by the Gulf Stream. It has been hypothesized that periodic methane eruptions (sometimes called “mud volcanoes”) may produce regions of frothy water that are no longer capable of providing adequate buoyancy for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without warning.
Publications by the USGS describe large stores of undersea hydrates worldwide, including the Blake Ridge area, off the coast of the southeastern United States. However, according to the USGS, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years.
