Yeah, I have to admit that I do not use airships as much as I would like for my steampunk game. In the setting they have big envelopes and large steam powered screws (props) on the sides of the gondola, somewhat akin to a steam powered heavy lift or Skyhook -
Look to see airships making a comeback in the years ahead.
Other flying machines in the setting include Kites (biplanes - both gliders and powered) and Screwjacks (four propped helicopters - tricky to fly, but very maneuverable - not much for legs though).
