Science still isn't able to explain these world mysteries

SS Ourang Medan - One theory about the cause of the crew's death is that the Ourang Medan was carrying chemicals, which could have released gases that lead the crew to suffocate. Then, the movement caused by the towing eventually made the ship explode. There are others, however, who say that this story is nothing more than a legend, or rather, a fishermen's tale. Nothing has been proven to this day.
