A major European car ferry operator financed the development of the British Thermo Skyship, a saucer shaped airship using helium and super heated air for lift and ducted thrust from turbofan engines for vertical take off and landing and for cruise flight. A 9.14 m (30 ft) diameter model of the ship has flown, from which will be developed a Skyship car ferry capable of carrying 60 passengers and their cars from England to France at 165 kph (103 mph), and 152 and 508 tonne (150 and 500 ton) cargo carrying saucers.
