The Bermuda Triangle
The stretch of the Atlantic between Florida, Bermuda and Puerto Rico where ships and planes are said to vanish, and what Navy, Coast Guard and NOAA records say about it.
The question Do ships and planes really vanish in the Bermuda Triangle more than anywhere else, and why?

The Navy collier USS Cyclops disappears with everyone aboard
Returning from a voyage to Brazil, the ship was never heard from again. The Navy’s museum says “her wreck has never been found and the cause of her loss remains unknown.” The Navy library calls it “the single largest loss of life in U.S. Naval history not directly involving combat”.

Five Navy Avenger torpedo bombers, Flight 19, are lost on a training flight
The 14 men left Naval Air Station Fort Lauderdale on a routine navigation exercise over the Bahamas. The instructor, Lt Charles Taylor, radioed “Both my compasses are out” and believed he was over the Florida Keys. No confirmed trace of the planes or the men has ever been found. The loss is recorded by the Navy itself, against its own interest, and by the base’s museum.

The PBM Mariner left Naval Air Station Banana River at 7:27 pm and made its last call three minutes later. The tanker SS Gaines Mills reported a burst of flames at 7:50 pm, and USS Solomons saw a plane vanish from radar at the same spot. The Navy’s accident card says it “exploded at sea for reason unknown”. Recorded by the Navy itself, as a loss of its own aircraft and men.

The Navy’s reports blame poor navigation and running out of fuel
Each Avenger’s accident card records the planes as lost through fuel exhaustion, gives poor navigation as the cause, and says the search from 6 to 10 December found nothing. The Board of Investigation found the leader “so hopelessly confused as to have suffered something akin to mental aberration.” Confirmed that the Navy found this; the Navy was judging its own instructor and its own training.

Vincent Gaddis’s Argosy article “The Deadly Bermuda Triangle” draws the Triangle on the map
He drew it from Florida to Bermuda to Puerto Rico and back, and wrote that the area had “claimed almost 1,000 lives” in two decades, in disappearances that “total far beyond the laws of chance”. A 1974 Military Sealift Command magazine credits him with putting the triangle “on the map”.

Charles Berlitz’s book The Bermuda Triangle says more than 100 planes and ships have vanished there
The Doubleday book says more than 1,000 lives were lost in 26 years “without a single body or even a piece of wreckage” being found. Among the explanations it lists are a “time-space warp”, UFOs and an Atlantean power source near Bimini.

A Military Sealift Command magazine checks the claims with the Navy’s own people
The director of the Navy’s Project Magnet survey said: “We have passed over the area hundreds of times and never noticed any unusual magnetic disturbances.” The article says German records after the First World War showed no U-boats or mines near the Cyclops, and calls the supernatural explanations “sheer hokum”. Held at Likely: it is one article in a Navy command’s own magazine.

Larry Kusche’s book The Bermuda Triangle Mystery—Solved calls the legend “a manufactured mystery”
Kusche had compiled a Bermuda Triangle bibliography at Arizona State University’s library in 1974. His book reports that the weather was bad in many of the incidents, that some losses credited to the Triangle happened in the Pacific or near Ireland, and that some incidents were fictional. “It began because of careless research,” he wrote.

NOAA and the Coast Guard: no sign that the area is more dangerous
The National Oceanic and Atmospheric Administration’s Ocean Service says “There is no evidence that mysterious disappearances occur with any greater frequency” there than in any other large, well-travelled area of ocean. It points to storms, the Gulf Stream and shallow water. The US Coast Guard, the rescue service in these waters, says it does not recognise the area as one of specific hazard.

Flight 19 and the Triangle
Did the Triangle swallow Flight 19?
Vincent Gaddis’s Argosy article made Flight 19 a centrepiece of the “Deadly Bermuda Triangle”, quoting a leader who could not tell west and saying something affected the compasses.

Six planes and 27 men vanished in a small area without a scrap of wreckage
Gaddis asks how six aircraft, the Mariner included, and twenty-seven men could “totally vanish in such a limited area”.
The premise: confirmedTrue that nothing was found: the Navy’s cards record a negative search. But a tanker saw flames where Training 49 was lost, and the Avengers came down at night in rough seas after running out of fuel.

Gaddis concludes that “all five compasses were thrown off” and that, on such a clear day, land should have been visible.
The premise: unverifiedThe records read show only the leader saying his compasses were out, not all five. The accounts say the weather worsened as night fell; those accounts are the Navy’s and the base museum’s.

The flight got lost, with a leader who doubted his compasses, then ran out of fuel
In the Navy’s account Taylor believed he was over the Florida Keys, while radio bearings put the flight north of the Bahamas and east of Florida. The accident cards record the planes as lost through fuel exhaustion; the base museum says they “apparently ran out of fuel”. Held at Likely: the Navy’s records are its own, and the museum adds one independent tier-2 account.

A British tanker in the area reported “tremendous seas and winds of high velocity”. A search pilot told the Board the air was very turbulent and the sea very rough.

Key claim: a force peculiar to the Triangle took the planes
No record attached supports it. The Navy’s reports give an ordinary probable cause, but since the 1947 correction the official finding is that the cause is unknown, which rules neither way.

Bullshit meter
- Key claim: a force peculiar to the Triangle took the planes. Unverified.
- Key claim contradicted by tier 1? Partly. The Navy’s accident reports give an ordinary probable cause (lost, out of fuel, in worsening weather), but the official cause has been “unknown” since 1947, so no tier-1 record rules on the Triangle claim directly.
Fluff meter: possibly planted
- Can’t be traced to an original record. Absent: the loss itself is in the Navy’s accident reports.
- First appeared from new or anonymous accounts. Not measured.
- Coordinated identical wording. Present: the 2024 Navy web page repeats, nearly word for word, the text the 1973 Navy magazine labelled “the popular version”. We compared the two.
- Cited source doesn’t exist. Absent: the Board of Investigation report is real; the Navy publishes its accident cards.
- Later contradicted. Present: the accounts built on the Board report (1973, 2021) give a different timeline and do not contain the eerie lines.
