the "devil's triangle"...
it once was a mystery to me until science finally got a concrete explanation about 'some' extra ordinary happenings in there.
one of which is the abnormal malfunctioning of a compass ('compass variation' - where the needle always points to magnetic north) within the said area. before it's been said that the alien intervention has something to do with it but finally discovered that the earth's magnetic field causes this odd phenomenon. Perhaps this fact also is responsible for the reported missing ships and planes back then.
although some are still not convinced with the explanation of science, I consider this as a "Solved Mystery."
