The document summarizes the mystery of disappearances in the Bermuda Triangle area between Florida, Bermuda, and Puerto Rico. Over 1,500 people have gone missing in aircrafts and ships over the last 60 years in this region. Some of the most notable incidents include the disappearance of USS Cyclops in 1918 with 309 crew, Flight 19 in 1945 when 5 bombers vanished, and ghost ships found abandoned. There have been many theories proposed to explain the phenomena, such as human error, crazy weather patterns, methane hydrates, and aliens, but none have been substantiated after massive research.
