The Bermuda Triangle is a region where a number of ships and planes have disappeared under mysterious circumstances. Popular culture attributes these disappearances to paranormal phenomena, but official agencies state the number of disappearances is normal. Proposed scientific explanations include human error, hurricanes, rogue waves, and pockets of methane gas bubbles exploding from the seafloor. Notable incidents in the Bermuda Triangle include the disappearance of Flight 19 in 1945 and an incident where a pilot's plane and instruments were strangely affected by a large cloud formation. While the causes of disappearances in the Bermuda Triangle remain unexplained in some cases, human mistakes and natural hazards can account for many incidents.
