The Bermuda Triangle is not dangerous. While the area is very heavily travelled, the rate of airline and shipping disappearances is no higher when compared to other parts of the world.
Explanations for disappearances in the Bermuda Triangle range from alien abduction, ship-sized methane bubbles and portals to other worlds. However, there are several logical explanations for the incidents that occur inside. The area is prone to sudden and violent storms. The Gulf Stream that runs through the area is very fast and turbulent and helps wash away debris from crashes. The Bermuda Triangle can be as deep as 30,000 feet, making it very difficult to find lost vessels or planes when they crash.
