There's a ship made of ice that sank in the Arctic - Apparently.
The MV Joyita, a 70-foot passenger vessel, set sail from Tonga in 1955 with 25 people on board. Two weeks later, the ship was found adrift, but all hands were missing. An investigation revealed that the ship had been deliberately scuttled, but the mystery of what happened to the passengers remains unsolved. The wreck was later located in the Pacific Ocean, but the incident remains one of the most bizarre maritime disasters in history.
