I can't find a picture of it all together, but I am now getting visions of Lionel Jeffries singing P.O.S.H out of the open door of his potting shed in 'Chitty Chitty Bang Bang'.
I believe the airship had two 3 bladed props at either end of it, so if viewed from the side, it could possibly appear to be a helicopter. (prior to Vfrpilots visit to 'Specsavers').
Perhaps another remake of a popular family film in progress?
