The Flying Dutchman is a cheat unit in Age of Empires. When Flying Dutchman is typed in the chat menu, it will turn your Juggernauts and Catapult Triremes into Flying Dutchmen, which is slightly more powerful and can also sail on the ground. If used effectively, the Flying Dutchmen can be an effective hit and run unit since it can outrun most kinds of infantry and slower units.
The Flying Dutchman is a reference to a nautical folklore. This mythical phantom ship is believed to be a sign of doom to sailors since it is cursed to sail the seas for eternity and can never rest at port.
The myth about the Flying Dutchman originates from ship lost in the 17th-century, which is not during the time period in which Age of Empires I is set.
