Airplanes do in fact fly through the area known as the "Bermuda Triangle." No scientific evidence exists to prove that this area is associated with paranormal activity or a high incidence of airplane and boat disappearances.
The Bermuda Triangle theoretically has its three points in the Atlantic island of Bermuda, Puerto Rico in the Caribbean and Florida. If airplanes did not fly in this area, there would be no airline service to locations such as the Florida Keys, which are supposedly located within the Bermuda Triangle. There is no evidence to support the idea that this area is any more dangerous to fly in than other parts of the world.
