The Bermuda Triangle

Summary

Ships and aircraft have been lost in the western Atlantic. That much is true and always was. What is not true is that they are lost there at an anomalous rate. Lloyd's of London and the United States Coast Guard have both examined the records and found nothing unusual. The Bermuda Triangle is not a place where the laws of physics falter. It is a case study in how a mystery gets manufactured, and it is the most instructive record in this archive.

What is documented

The region does not officially exist. The Bermuda Triangle appears on no nautical chart. It has no agreed boundaries. The usual description is a triangle with corners at Miami, Bermuda and San Juan, but authors have drawn it differently, and some have extended it as far as the Azores. The area is one of the most heavily trafficked stretches of ocean on Earth, crossed constantly by commercial shipping, cruise traffic and aviation.

Where the name came from. Vincent Gaddis published an article in Argosy magazine in 1964 giving the region its name. The idea became a global phenomenon with Charles Berlitz's book The Bermuda Triangle in 1974, which sold in enormous numbers.

The incidents are real. People died. In December 1945, five US Navy Avengers on a training flight, known as Flight 19, were lost with fourteen men aboard; a Mariner flying boat sent to search for them was lost with thirteen more. The USS Cyclops vanished in 1918 with over three hundred aboard. The BSAA aircraft Star Tiger was lost in January 1948 with thirty-one people, and its sister aircraft Star Ariel in January 1949. These are not inventions. They are losses at sea, and they were investigated as such.

Kusche's method. In 1972 Larry Kusche, a reference librarian at Arizona State University, set out to compile everything that had been written about each incident. He did not begin with a thesis. He went back to the primary sources: Coast Guard records, Air Force files, Lloyd's of London, and microfilmed newspapers from the cities where the events were reported. He published the results in 1975 as The Bermuda Triangle Mystery: Solved.

What Kusche found. The pattern was consistent across case after case:

• Ships described as vanishing in calm seas had in fact gone down in storms. The weather was in the record, and the Triangle authors had not mentioned it.
• Vessels said to have disappeared without trace had been found, with a documented cause of loss.
• Some incidents had occurred well outside any version of the Triangle's boundaries.
• One vessel listed as lost in the Triangle had actually sunk in the Pacific, roughly three thousand miles away. The author had confused a Pacific port with an Atlantic city of the same name.
• The disappearance of the yachtsman Donald Crowhurst was presented as a mystery, despite clear contrary evidence in the public record.
• Some accounts, such as the Ellen Austin story, could not be traced to any primary source at all. They were retellings of retellings.
• Some incidents had not happened.

Kusche described the result as a manufactured mystery.

Lloyd's of London. When Channel 4 produced a programme on the Triangle for the Equinox series in 1992, it asked Lloyd's, the marine insurance market, whether an unusual number of ships had been lost in the region. Lloyd's found that they had not. Lloyd's does not charge a higher premium for passage through the area, and never has. This is a market with every financial incentive to identify a genuinely dangerous stretch of water and price it accordingly.

The United States Coast Guard. Coast Guard records confirm the same conclusion. The Coast Guard's position is that the number of incidents in the region is not out of proportion to the volume of traffic through it. The National Oceanic and Atmospheric Administration has reached the same finding.

Leading explanations

There is nothing anomalous to explain. What requires explanation is the belief, and that has an answer.

Base rates. The region carries a very large amount of traffic. A large number of transits produces a number of losses. Presented without the denominator, any absolute count of incidents looks alarming. Presented with it, the rate is unremarkable.

Selection. A collection assembled by searching for mysterious losses in one area will contain only mysterious losses in that area. Nothing about the collection can then tell you whether that area is unusual, because the comparison was never made.

Removal of the explanation. This is the mechanism Kusche documented, and it is the important one. In case after case the storm was omitted, the wreckage was omitted, the official finding was omitted. What remained was a ship that vanished in calm water for no reason. The mystery was not discovered. It was produced, by subtraction.

Ordinary causes. The area has genuine hazards: sudden and severe weather, the Gulf Stream, which disperses wreckage quickly, shallow banks, and, historically, heavy amateur traffic. These account for losses without requiring anything further.

Methane hydrates, magnetic anomalies, Atlantis, spacetime rifts. Proposed as mechanisms. None is needed, because there is no elevated loss rate for a mechanism to cause.

Current status

Debunked. The registry does not keep this record grudgingly. It keeps it as the founding case.

Kusche's method was to take each claim, go back to the document underneath it, and see what the document actually said. That is the entire editorial standard of this archive, applied to one legend, and it dissolved it. What he found was not a supernatural region but a process: a real loss, stripped of the storm, stripped of the wreckage, stripped of the coroner's finding, and passed to the next author, who added something that was never there.

Every case in this register is at risk of that same process. The Bermuda Triangle is what it looks like when nobody checks.
