    Sea monster vs. the submarine UB-85

    I love reading stories like these. Mysterious U-boat may have been found.

    USS Pennsylvania - The U.S. Navy largest submarine

    Pretty interesting video to watch. Neat to see how the oxygen is made. I can't imagine being down there for so long. Talk about a mental load on someone.
