The Bermuda Triangle, also known as the Devil's Triangle, is an undefined 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. According to the US Navy, the triangle does not exist, and the name is not recognized by the US Board on Geographic Names. 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 a 2013 study, the World Wide Fund for Nature identified the world’s 10 most dangerous waters for shipping, but the Bermuda Triangle was not among them. Contrary to popular belief, insurance companies do not charge higher premiums for shipping in this area.
Unexplained disappearance is the physical disappearance of people or other objects without apparent cause or reason.
Cultural anthropology is a branch of anthropology focused on the study of cultural variation among humans and in contrast to the social anthropology perceives the cultural variation more as an independent "variable" than the dependent one.
A variety of methods, including participant observation, often called fieldwork because it involves the anthropologist spending an extended period of time at the research location, but also interviews and surveys are part of anthropological methodology.
Flight 19 was the designation of five TBM Avenger torpedo bombers that disappeared over the Bermuda Triangle on December 5, 1945 during a United States Navy overwater navigation training flight from Naval Air Station Fort Lauderdale, Florida. All 14 airmen on the flight were lost, as were all 13 crew members of a PBM Mariner flying boat assumed by professional investigators to have exploded in mid-air while searching for the flight. Navy investigators could not determine the cause of the loss of Flight 19 but said the aircraft may have become disoriented and ditched in rough seas after running out of fuel.
In international human rights law, a forced disappearance (or enforced disappearance) occurs when a person is secretly abducted or imprisoned by a state or political organization or by a third party with the authorization, support, or acquiescence of a state or political organization, followed by a refusal to acknowledge the person's fate and whereabouts, with the intent of placing the victim outside the protection of the law.
According to the Rome Statute of the International Criminal Court, which came into force on 1 July 2002, when committed as part of a widespread or systematic attack directed at any civilian population, a "forced disappearance" qualifies as a crime against humanity and, thus, is not subject to a statute of limitations. On 20 December 2006, the United Nations General Assembly adopted the International Convention for the Protection of All Persons from Enforced Disappearance.
