The Bermuda Triangle
Lloyd's of London and the US Coast Guard both report no unusual loss rate in the area. The famous disappearances turn out to involve storms, fuel exhaustion, and in several cases ships that sank somewhere else entirely.
Why this verdict
Debunked by insurance and coastguard statistics: the region's loss rate is not elevated relative to traffic volume, and the canonical cases dissolve when checked against contemporary records.

01The claim
That an area of the western North Atlantic bounded roughly by Miami, Bermuda and Puerto Rico is the site of an anomalous number of ship and aircraft disappearances, attributable to magnetic anomalies, methane hydrate eruptions, or non-natural causes.
02Where it came from
The idea was assembled in the popular press: an Associated Press piece by Edward Van Winkle Jones in 1950, an American Legion magazine article in 1962, and above all Vincent Gaddis's 1964 Argosy article, which named the 'Deadly Bermuda Triangle'. Charles Berlitz's 1974 bestseller made it global. Larry Kusche, a research librarian at Arizona State, then did the obvious thing nobody had done: he went to the original records.
03What the record shows
✕ DEBUNKED — Investigated and refuted. Here is what actually happened.
Kusche's 1975 investigation checked each canonical case against contemporaneous newspapers, Lloyd's records, and Coast Guard and Navy reports. The findings were consistent. Several 'disappearances' occurred outside the triangle — one ship was lost in the Pacific. Several occurred in severe storms that the popular accounts omitted. Some vessels were never reported missing at all. In multiple cases the mystery had been generated by an author's failure to check a date or a location.
Flight 19, the five Avenger torpedo bombers lost in December 1945, is the anchor case and has a mundane reading: a training flight whose lead instructor became disoriented over unfamiliar water, believed himself over the Florida Keys when he was over the Bahamas, and led the flight further out to sea until fuel ran out at night in worsening weather. The Navy's original board attributed it to pilot error; the finding was later amended to 'causes unknown' after a request from the instructor's family. One of the search aircraft, a PBM Mariner, exploded shortly after take-off — a type with a known reputation for fuel vapour ignition, and a tanker crew reported seeing the explosion.
The statistics are the strongest evidence. The area contains some of the world's busiest shipping lanes and heaviest recreational boating traffic, and it sits in the hurricane belt with the Gulf Stream running through it, which disperses debris rapidly. Lloyd's of London has stated it does not rate the area as unusually hazardous and charges no premium for it. The US Coast Guard's position is the same. The World Wide Fund for Nature's 2013 analysis of the ten most dangerous shipping areas did not include it.
04What it cost
A durable and mostly harmless piece of publishing folklore, and the best available demonstration of a specific error: defining a region after selecting the events, then treating the resulting cluster as significant. The same mistake underlies a great deal of more consequential claim-making, from cancer clusters to crime statistics.
