The legend of the Flying Dutchman concerns a ghost ship that can never make port, doomed to sail the oceans forever. It probably originates from 17th century nautical folklore. The oldest extant version dates to the late 18th century. Sightings in the 19th and 20th centuries report the ship to be glowing with ghostly light. It is said that if hailed by another ship, its crew will try to send messages to land or to people long dead. In ocean lore, the sight of this phantom ship is a portent of doom. //wikipedia
