The Bermuda Triangle is a minor myth in GTA San Andreas and GTA V. The myth began sometime in 2007, when multiple players and users claimed that if you fly an aircraft far enough out into the ocean, you will lose control of your plane and the plane will crash into the water and you will get teleported to somewhere in San Andreas and receive a one-star Wanted Level. Though, the Bermuda Triangle is the large patch of ocean between Puerto Rico, Florida, and the Bermuda Islands, and GTA San Andreas takes place in California and Nevada, nowhere near the original myths location. There is very little evidence to support this myth. The disappearing myth is true, but that is a game mechanic, making this myth FALSE.
This also happens with boats. The boat will flip upside down and float on top of the water. But, when this happens, the player will not respawn, meaning they will be stuck in the middle of nowhere, they can only escape by either using cheats, swimming for hours, or the player committing suicide.
In GTA V, flying too far away from San Andreas will cause the engine of your plane to explode before crashing in the ocean. Shall the player survive the crash, it is likely that he/she will soon after be eaten by a shark. Making the existence of the Bermuda Triangle in GTA V PROVEN.
