Gulf stream is nothing but the ocean current which originates in the gulf of Mexico and passes through Bermuda triangle via straits of Florida, North Atlantic. It forms itself like a river in a ocean that can easily waft the floating objects like ships and other water-crafts with it. And even an aircraft which is flying near the water level can be affected.
Lots of storms are raised in Bermuda Triangle very often and very quickly. These storms are so quick that even a satellite doesn't predict such storms. And if a ship is moving through that area, there is always a chance to sink.
Hurricanes are also very powerful storms which rise from South Eastern Atlantic and pass through the Bermuda triangle. These hurricanes also cause loss and extreme damage in that particular area. Mostly these originate in the months of June to November.
Human errors also could not be neglected for such accidents. As Bermuda Triangle area is very vast and has lots of identical islands. So it is very often that they move towards wrong direction. And after realizing the errors, it is quite late to return and refuel the ship because after covering such a long way, ship runs out of fuel.
Like every other controversial topic, Bermuda Triangle also debated by some other views. Critics believe that there is nothing uncommon here. It is a vast area and the main area to connect the Europe, Caribbean Islands & US Coast. They say that authors wrote many fake and imaginary stories to get easy publicity and media supports them because such kinds of books are highly demanded in the market. As this area is very much affected by Hurricanes, it is very common to meet with such accidents.
