   "This airship flies from the upper atmospheric station to orbit.  It uses   
   hybrid chemical/electric propulsion to slowly accelerate and reach orbit.

   space.   The station acts not only as a port for the orbital airship but also   
   as a research center, construction site and tourist destination."
