It was another battle in a long war: American Navy ships sunk the German submarine U-550 in 1944.
For 68 years, the sub lay on the ocean bottom off Nantucket, allegedly in waters divers could reach, but its exact location unknown. Until divers found it: the last undiscovered U-boat in divable waters.
How divers finally located it and what they found at the wreck scene is the story Randall Peffer tells in Where Divers Dare. He joins us to talk about just how daring the mission to find U-550 was.
