Bermuda Triangle also known as Devil's Triangle, which is located in the western part of the North Atlantic Ocean. It is the triangular space between Florida, Bermuda, and Puerto Rico as seen in the below image. Number of aircraft and ships are said to have disappeared under mysterious circumstances. Many ships sail, and aircraft's regularly fly over it.
On 5th December, 1945 Flight 19, five Grumman TBM Avenger torpedo bombers disappeared in the traingular area with 14 member team where none of them were survived, and no debris found. To search for the missing, Martin PBM Mariner flying boat with 13 member crew was launched from Naval Air Station Banana River which never returned nor neither of them on board survived, which might exploded in mid-air.
The flight leader was "Charles Carroll Taylor" with other student pilots, and a trainee pilot had the role of leader out front. Each flight was fully fueled, and during pre-flight checks it was discovered they were all missing clocks. Almost after completion of training, Taylor who lost his direction, as two of his compasses which stopped working. He got confused and believed to travel till fuel was exhausted, went missing. Later the incident, several other planes too went missing in the triangular area.
Incidents happened with cruise as well. USS Pickering, USS Wasp, USS Wild Cat etc were missed for unknown reasons, people on board too disappeared. I think there are no paranormal activities in with Bermuda Triangle. But could notice compass variations because of unusual local magnetic anomalies which may exist in the area.
Most of the explanations in official inquiries on loss of any aircraft or vessel are found to be "Human Error".
