Researchers in the US claim they have discovered the answer to the mystery of the Bermuda Triangle.

Covering more than half a million square miles of ocean located between Bermuda, Florida and Puerto Rica, the term "Bermuda Triangle" was first coined by writer Vincent H. Gaddis in 1964.

The area is notorious for (legend has it) the unusually high number of planes and ships that go missing there without trace.

In a new Science Channel documentary, meteorologists claim that an unusual type of cloud located in the region could be behind a number of the disappearances.
