Good question! It technically speaking isn’t an actual feature, more of a myth. Its a loosely defined region, where the points of the triangle are Bermuda, southern tip of Florida and Puerto Rico, where ships and planes disappear in mysterious fashion! The count is about 75 incidents. There has been a theory recently that meteorologists came up with of ‘air bombs’ (small areas where winds can be really high 200km/hr+) that overturn ships or down planes. That’s a plausible explanation, but it’s never been tested in reality.
