Also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean where numerous aircraft and ships have disappeared under mysterious circumstances. The triangle is roughly bounded by Miami, Bermuda, and Puerto Rico. The term "Bermuda Triangle" was first coined by writer Vincent Gaddis in a 1964 article for Argosy magazine. Since then, it has become a popular subject of speculation and conspiracy theories. However, many experts argue that the number of disappearances in the Bermuda Triangle is not significantly higher than in any other heavily trafficked area of the ocean. Some of the most famous incidents associated with the Bermuda Triangle include the disappearance of Flight 19 in 1945, a group of five U.S. Navy torpedo bombers that vanished during a training exercise; the disappearance of the USS Cyclops in 1918, a U.S. Navy cargo ship carrying over 300 crew members; and the vanishing of the SS Marine Sulphur Queen in 1963, a T2 tanker carrying molten sulfur.

Numerous theories have been proposed to explain the disappearances in the Bermuda Triangle, ranging from paranormal explanations to natural phenomena. Some popular theories include magnetic anomalies affecting navigational instruments, underwater methane gas explosions, rogue waves, and even extraterrestrial activity. However, none of these theories have been proven beyond doubt. In reality, many of the incidents attributed to the Bermuda Triangle can be explained by human error, adverse weather conditions, or technical malfunctions. The area experiences frequent tropical storms and is known for its unpredictable weather patterns. Additionally, the high volume of air and sea traffic passing through the region increases the likelihood of accidents and disappearances. Despite the mystery surrounding the Bermuda Triangle, it continues to attract public fascination and remains a subject of ongoing research and investigation.
