Trust science to take all of the steam out of a good mystery. For a long time, the disappearance of ships in the Bermuda Triangle was explained by fringe dwellers are due to aliens, who had an underwater base there, the stuff of great movies. There is plenty on the internet about that. Scientists think that there is a non-alien explanation, based on rogue waves:

“The experts simulated the waves as part of a Channel 5 documentary ‘The Bermuda Triangle Enigma’. As part of the show, the scientists made a model of the USS Cyclops, a 542 ft coal vessel which vanished in the Bermuda Triangle in 1918. No wreckage or the remains of any of the 306 crew members were ever found. However, the team found that due to the massive size of the ship, the waves which were as tall as 100ft (30 metres) easily took down the ship – according to the simulation.”
Now that is pretty good, worth a gold star in fact. But, wait … waves are in the water, right? Well, what about the plane crashes?

That cannot be due to anything in the water, as the planes are in the air. So back to the drawing board. Sure, it is a technology failure:

But, why? Aliens seemed to be more fun, and sold heaps of books to bored folk looking for something to fill in the time on a rainy Saturday afternoon. Electromagnetic disturbances because of some natural phenomenon, are a bit of a yawn.
