A naval collier with 306 aboard vanishes without a distress call. Five military bombers disappear, and the rescue plane sent after them explodes. The Bermuda Triangle is the ultimate maritime ghost story, but here is the twist: the legend wasn't born among sailors. It was manufactured by magazine writers, starting with a 1950 wire story and a 1952 piece in a pulp called Fate, then inflated by 1970s paperback authors who stretched the triangle's borders as far as Ireland whenever they needed another shipwreck.

This episode strips the sensationalism from the cornerstone cases and examines the actual mechanics: the manganese ore that could snap the USS Cyclops in half, the navigation failure and empty fuel tanks behind Flight 19, the Gulf Stream's evidence-scattering velocity, and the methane trap-door theory that works in a lab but has no geological support in the Triangle. The real story is a case study in how curated data and sensational storytelling build a myth that outlives the facts.
