I think the Bermuda triangle is on a case by case, some explainable others unexplainable. For example.
Flight 19, got lost, and ditched into the atlantic. The TBM-3 Avenger is a very heavy bird, she would have sank like a stone by ditching. Would have been very difficult to escape in time, and even if hypothermia would have killed the pilots within minutes. The dissappeance of the Rescue PBY is an odd coincidence.
USS Cyclops, probably Espionage. Happened during the height of WWI. Pro-German Captian and several members of crew. The unexpected embarkation of a very pro-german US consulate is very odd. She probably sailed off her route as was destroyed in some fashion.
SS Sulfur Queen, she was carrying liquid sulfur (explosive). Unlike the others debris was found, she most likely exploded and sank with minutes.
Then there were several ships where the ship was found intact, but the passengers and crew dissppeared. Pirates is one possibility.
