On May 23, 1939, the United States submarine USS Squalus sank off Portsmouth, New Hampshire, with all hands. But 32 of the crew plus one civilian worker were rescued the next day. One hundred thirteen days after the disaster the Squalus was in drydock. It had been raised from 242 feet by the valiant efforts of 53 divers. They risked their lives making 640 dives during the desperate, frustrating work. For the sixth and last time, the Squalus had been raised.
