The Ship Found Sailing With No One Aboard

On 4 December 1872, the crew of a small brigantine found another ship drifting in the Atlantic, between the Azores and Portugal. Her sails were half set. Her hold was full of cargo. There was food for six months and water to spare. The ten people aboard — the captain, his wife, their two-year-old daughter and a crew of seven — were gone. For a hundred and fifty years the Mary Celeste has been blamed on pirates, mutiny, fraud and sea monsters. But much of what people "know" about her comes from fiction, including a short story by a young Arthur Conan Doyle. In this video we separate the 1872 record from the legend, test each major theory against what was actually found on board — including a 2026 re-run of the alcohol-vapour experiment — and give our verdict on what most likely happened.
