Hunt for Eagle 56

On April 23, 1945, the U.S. Navy warship USS Eagle 56 exploded off the coast of Portland, Maine due to a malfunction of the ship's boilers...or so the official report said. A civilian-led dive expedition attempts to discover the lost wreckage and find out what really happened, uncovering fresh clues, startling eyewitness accounts, and a possible cover-up.
