In 1872, a ship named Mary Celeste was found sailing without its crew . 154 years later, the mystery of what happened to the sailors remains unsolved despite several searches. The merchant ship was discovered in the Atlantic Ocean with no people aboard. Its cargo and supplies were still on the vessel. The ship was also in a condition that allowed it to continue sailing. The discovery raised questions because there was no clear reason for the captain, his family and the crew to leave the vessel. The ship's lifeboat was missing, but there was no confirmed evidence showing where the people had gone. The crew was never found.
