The USS Arizona has been resting on Pearl Harbor's ocean floor for the past 75 years. For the first time since it was destroyed in 1941, scientists have the technology to take an in-depth look inside the ship. Once considered the pride of its fleet, the Arizona has taken on drastic changes in the shallow waters of the Pearl. This comprehensive search of the USS Arizona sheds light on one of the darkest days in American history. The discoveries made inside the ship are a stark reminder of all those who paid the ultimate price for their country. The expedition retells personal stories of survivors who lived through Japan's surprise attack on Pearl Harbor. It also brings a survivor who was aboard the Arizona back to see the ship for what might be one last time. A sight he never thought he'd see again.
