The Bermuda Triangle, the Atlantic Ocean
It completely disappeared ships and aircraft, and navigation devices would not work. The reason — a lot of shoals and often emerging here cyclones and storm.
The Bermuda Triangle, also known as the Devil’s Triangle, is a loosely-defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. Most reputable sources dismiss the idea that there is any mystery. The vicinity of the Bermuda Triangle is one of the most heavily traveled shipping lanes in the world, with ships frequently crossing through it for ports in the Americas, Europe, and the Caribbean islands. Cruise ships and pleasure craft regularly sail through the region, and commercial and private aircraft routinely fly over it.
Popular culture has attributed various disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors.
In 1964, Vincent Gaddis wrote in the pulp magazine Argosy of the boundaries of the Bermuda Triangle: three vertices, in Miami, Florida peninsula, in San Juan, Puerto Rico, and in the mid-Atlantic island of Bermuda. Subsequent writers did not necessarily follow this definition. Some writers gave different boundaries and vertices to the triangle, with the total area varying from 1,300,000 to 3,900,000 km2 (500,000 to 1,510,000 sq mi). Consequently, the determination of which accidents occurred inside the triangle depends on which writer reported them. The United States Board on Geographic Names does not recognize the Bermuda Triangle.
