BOLTENHAGEN: Slowly, Dirk Schoenen dives down to a huge pile of ammunition from World War II at the bottom of the Baltic Sea. He removes some of the top pieces and carefully puts them into a basket, as a team of engineers, divers and seamen watch his every move on monitors streaming live video from a camera attached to his head. After an hour, the men pull Schoenen back up onto the Baltic Lift, a mobile platform located 6 kilometers (3.7 miles) off the small town of Boltenhagen on the German coast.
