Actually, the Bermuda Triangle doesn't have any more or fewer 'incidents' than any other comparable area.
The fact that it is notable shows that the human mind seeks out patterns and is liable to attribute supernatural explanations to things they can't explain.
And, as science usually does, it has found that methane could be the culprit in some of the shipwrecks and magnetic anomalies may account for aircraft being lost.
(There are many places in the world where the Earth's magnetic field is irregular. Off the top of my head I know that the coast of Maine has one too.
It's actually denoted on aviation charts.)
Most of the aircraft disappearances happened before more modern navigation systems were developed and the magnetic compass was the only directional instrument available.
Not surprisingly, the introduction of radio navigation, inertial navigation, and GPS systems seems to have ended any problems for aircraft transiting the area.
