Sights and activities not ordinarily seen by visitors who come to Washington, DC are visited in this episode continuing the cruise on the Potomac River. The episode begins with a visit to the busy Washington National Airport and ends with a visit to Fort Washington, with its drawbridge and moat, built 140 years ago to guard the capital from attack. In route the visitors stop at the Washington Navy Yard and witness deep sea divers descending into the muddy depths, see a diver working underwater with an acetylene torch, see submarines, a captured Japanese tank, a destroyer escort, the Kennedys yacht Honey Fitz, and the depot for the Presidents helicopter fleet. They also sail by historic Alexandria, VA and Mt. Vernon, George Washingtons Virginia home on the Potomac River.
