On the afternoon of 5 December 1945, five US Navy Avenger torpedo bombers took off from Fort Lauderdale, Florida, on a routine training exercise called Flight 19. Their instructor, Lieutenant Charles Taylor, an experienced combat pilot, became convinced his compasses had failed and that the flight was over the Florida Keys when it was actually east of the peninsula, over the Atlantic. Radio transcripts record hours of confused course changes as Taylor led his students further out to sea into darkening weather. The five aircraft ran out of fuel and ditched; all fourteen airmen were lost. That night a Mariner flying boat sent to search for them exploded in mid-air with thirteen crew aboard — a tanker crew saw the fireball, and the Mariner type was so notorious for fuel-vapour leaks that sailors called them flying petrol tanks.
A grim, explicable tragedy, then: a disorientated flight leader, night, weather, and a search aircraft with a known fatal flaw. But Flight 19 had the misfortune to disappear in the patch of ocean between Florida, Bermuda and Puerto Rico, and so it became Exhibit A in one of the twentieth century's most profitable mysteries.
Building the triangle
The legend was constructed in visible stages. A 1950 Associated Press piece first mused on disappearances in the region; a 1952 magazine article drew the boundary lines; and in 1964 the writer Vincent Gaddis, in the pulp adventure magazine Argosy, gave the region its name: the Deadly Bermuda Triangle. The gold rush came in 1974 with Charles Berlitz's book The Bermuda Triangle, which sold millions of copies and folded in everything from Atlantis to alien abduction. Along the way the triangle absorbed stories that never belonged to it — the Mary Celeste, found drifting and crewless in 1872, is a fixture of triangle lore despite having been discovered off the Azores, on the far side of the Atlantic.
The mystery's best genuine case is the USS Cyclops, a navy collier that vanished in March 1918 en route from Barbados to Baltimore with 306 people and a heavy cargo of manganese ore — still the largest single loss of life in US Navy history not caused by combat. No wreck was ever located and no distress call was ever heard. Yet the mundane explanations queue up: an overloaded ship of a class that later lost two sister vessels in strikingly similar circumstances, a dense and corrosive cargo it was not designed to carry, and heavy weather reported along her likely course.
The librarian who checked
The triangle met its match in Larry Kusche, a librarian and pilot at Arizona State University, who did the thing none of the mystery writers had done: he looked up the original records. His 1975 book The Bermuda Triangle Mystery — Solved found that the legend dissolved on contact with sources. Vessels said to have vanished in calm seas had sailed into documented storms. Losses placed inside the triangle had happened hundreds of miles away, or years earlier than claimed. Some ships could barely be shown to have existed. The mystery, Kusche concluded, was manufactured — by sloppy research, embroidery and writers copying each other's errors.
The actuaries agree. Lloyd's of London, which has been pricing marine risk since the seventeenth century, has stated that the triangle is no more dangerous than any other stretch of busy ocean, and it charges no additional premium for passage through it — an underwriter's verdict, backed by money rather than mood lighting. The US Coast Guard takes the same position and does not recognise the Bermuda Triangle as a hazard, noting that the region combines some of the world's heaviest sea and air traffic with hurricanes, the swift Gulf Stream and an abyssal seabed that swallows wreckage. More traffic plus fast-moving water plus deep ocean equals more accidents and fewer recovered wrecks — no third dimension required. A World Wide Fund for Nature review of the most dangerous shipping waters, published in 2013, did not place the triangle among its top ten.
The Bermuda Triangle is best understood not as a place but as a publishing phenomenon: a region of ocean no deadlier than its neighbours, wrapped in a brand so strong that insurers, coastguards and card catalogues have never managed to sink it. The sea keeps its secrets everywhere; only here did the secrecy get a logo.
