The Bermuda Triangle may have a better explanation than alien abduction. Though, it might be just as strange. They're called "Rogue Waves".

These waves have been measured as high as an 8-story building. Hypothetically, they could get as large as a 24-story building. These things roam the oceans, far from land - and were pretty unpredicatble until recently.

Scientists had, until about the year 2000, regarded the phenomenon in the same light as mermaids and the Loch Ness monster.
