Landing lines trail, and bow dips, as a Navy blimp nuzzles up to its mooring mast at completion of the day's mission. Other ships of the unit hover, meanwhile, over the field awaiting their turn. Note mooring man at the mooring swivel atop the portable mooring mast. He will take a line from the blimp's nose to make the ship snug to the swivel. (http://www.naval-airships.org/page-770913)
