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

"A two mile wide station parked at 140,000 feet is the new way station to space. The station acts not only as a port for the orbital airship but also as a research center, construction site and tourist destination."
