Bermuda

The Bermuda Triangle is actually located over quite a large area of the Atlantic Ocean. The points of the uneven triangle are the tiny island of Bermuda, San Juan, Puerto Rico and Miami, Florida.  Though the Bermuda Triangle was only named just over 60 years ago, there have been reports of missing ships and then planes since long before then. In fact, over the last 500 years, over 1000 ships and planes have gone missing in the Bermuda Triangle.
Why do ships dissappear?
One of the prevailing theories of skeptics to explain a lot of the disappearances in the Bermuda Triangle is simple human error. They claim that it is a huge area with a wide expanse of blue skies and blue ocean and similar looking tiny islands and it is easy to lose your way. Surely this could explain a small number of the missing craft, but it's hard to imagine that that many experienced pilots and navigators could lose their way so easily, even before GPS.  Another theory for at least some of the disappearances of ships can be attributed to piracy which has been a problem for the area for hundreds of years. And it's a perfect cover story for the pirates. Missing ship? It wasn't us, it was the Triangle!  One of the prevailing theories of what could be causing all of the disappearances in the Bermuda Triangle is pockets of methane gas that are trapped beneath the surface of the ocean floor under the Bermuda Triangle. They are then released due to seismic events or landslides, rising to the surface of the water, causing any ship in the path of the methane bubble to lose buoyancy and sink. There even theories that the methane could keep traveling into the air and stall an airplane's engines or even spark a fire.  A more likely explanation for some of the disappearances is bad weather, which the Bermuda Triangle is famous for. Hurricanes travel right through the area every year. The Atlantic's Gulf Stream also cuts right through the Triangle, causing strong currents that can be hard to handle.  The Sargasso Sea is home to seaweed of the genus Sargassum, which floats en masse on the surface there. The sargassum is not a threat to shipping, and historic incidents of sailing ships being trapped there are due to the often calm winds of the horse latitudes. Horse latitudes or subtropical highs are subtropical latitudes between 30 and 38 degrees both north and south. This region, under a ridge of high pressure called the subtropical high, is an area which receives little precipitation and has variable winds mixed with calm.  It partially overlaps the Bermuda Triangle. There are stories of ships getting caught in the middle of the sea and being stranded, motionless.
