National Geographic: Return of the Ghost Ship

To be clear: the "ghost ship" that serves as the focus of this National Geographic documentary special isn't actually a ghost at all, but a centuries-old wooden vessel - one of the most intact wrecked ships ever found. The explorers in this program journey to the craft's resting place at the bottom of the Baltic Sea, and use a combination of maritime archaeology and cutting-edge technology to recover artifacts from the ship and obtain the dimensions that will enable them to create a 3D model of it.
