GEnuine endoskeletal zeppelin, or "just" a mid-sized motorised blimp? (See "View to a Kill")
I was lucky enough to see a motorised blimp up close under unusual circumstances. It was at a local airfield, obviously testing its control surfaces as I was driving by - I pulled over, entranced, to watch. It was literally leaping & rolling like a dolphin, albeit slower. Truly wonderful to watch.
