Nearly 80 years ago, the USS Grunion submarine sank on its inaugural mission during World War II, taking the lives of 70 sailors with it as it plunged to the bottom of the Pacific. Now, after years of searching, a team looking for WWII-era submarines has found the Grunion's bow about 2,700 feet (820 meters) under the water's surface, off the coast of the Aleutian Islands in Alaska.
