The Bermuda Triangle is an area in the western part of the North Atlantic Ocean where a number of aircraft and ships are said to have disappeared under mysterious circumstances. Over the past 500 years, at least 50 ships and 20 aircraft are reported to have vanished in the Triangle, sometimes without a trace. While some theories propose supernatural or alien explanations, scientists argue that the number of disappearances is consistent with the level of sea traffic and weather conditions in the area. The causes of the incidents therefore remain unexplained.
