Originally produced by the Coast Guard as a sales pitch to commercial shipping lines to adopt LORAN (as a both a navigational aid and to assist in distress situations), this film details the wartime history of LORAN, its functionality and theory, and a dramatization of a shipping magnate being one over by a Coast Guard officer and commiting to acquiring LORAN receivers.
