The SS Ourang Medan was a Dutch cargo ship that reportedly sank in the late 1940s in the Strait of Malacca. The ship became famous due to the mysterious circumstances surrounding its distress signals, which claimed that the crew had died under strange conditions. After the ship was located, rescuers found it abandoned, with no sign of the crew. The vessel eventually caught fire and sank, leading to speculation about its fate. The incident has inspired various theories, including tales of ghosts and supernatural events, but no definitive evidence has been found to explain the mystery.
