The Bermuda Triangle (1973) by Charles Berlitz explores the mysterious disappearances of ships and aircraft in the Western Atlantic region, focusing on the area between Bermuda, Florida, and Puerto Rico. Berlitz suggests that these phenomena may be linked to the lost city of Atlantis, paranormal activity, or extraterrestrial interference. Drawing on evidence from past disappearances, such as the 1945 Flight 19 incident, and survivor accounts, Berlitz presents his theory, despite criticism from skeptics. The book also touches on alternative theories, including the Bermuda Triangle as a portal to Hell or a site of alien abductions, though these ideas are largely unproven. Berlitz challenges conventional explanations, proposing that unusual phenomena and even extraterrestrial life could be responsible for the mysteries of the area.
