Great footage of American airships being used to spot U-boats in the Atlantic Ocean.
Titles read: "U-BOAT SPOTTING".
High angle shot of several American airships in an aircraft hangar (?). Men of the United States Navy climb into the gondola (the cabin beneath the balloon) and we see various shots of the ship flying above the sea, scanning the area for U-boats. Views on board show the men looking out of the windows, operating the controls and contacting ship and shore stations by radio.
