evidence: SS Cotopaxi was assumed swallowed by the infamous Bermuda Triangle after the steamship, and all 32 crew members on board, inexplicably vanished in 1925. The SS Cotopaxi—an American merchant steamer—left Charleston, South Carolina, on Nov. 29, 1925, with a cargo of coal, destined for Havana, Cuba, but the vessel didn't make it far. The vessel vanished without a trace and the fate of the Cotopaxi and the 32 people on board has long puzzled experts. "The Cotopaxi was on a routine voyage," marine biologist and underwater explorer Michael Barnette told Newsweek. "She was employed in the coal trade and so this was just another trip at the end of November of 1925. We know that on that voyage something happened because she delivered a mayday message early December saying she's in distress.
