The Sea Hunters visit New Jersey to search for the remains of the US Navy airship Akron, and follow the trail along New York's East River to the site of test dives of Julius Kroeh's Sub Marine Explorer. Jim and Mike examine a piece of light aluminum alloy girder from the wreck of the US Navy airship Akron, which crashed and sank into the Atlantic off New Jersey in April 1933. Only three men survived the crash, but another survivor was crew member John Lust, who remained behind in the hospital after a bad car crash. The Sea Hunters, working inside the Akron's hangar at Lakehurst, New Jersey, are interviewing Mr. Lust before they head out to see to try and find the lost dirigible's remains. Sea Hunter John Davis pores over the ship's records while Mr. Lust joins Mike and Jim in discussing the construction of Akron.
