And US company Moller International has put a flying saucer into production that looks remarkably like George's perspex topped transportation.
The personal flying pod, called the M200G Volantor, can glide three metres off the ground and carry two passengers.
The M200G is the size of a small car and takes off and lands vertically.
Company founder Dr Paul Moller said the craft was “the ultimate off-road vehicle” because it can travel over any surface.
“It's not a hovercraft, although its operation is just as easy. You can speed over rocks, swampland, fences, or log-infested waterways with ease because you're not limited by the surface.”
The flying saucer is governed by computers to fly at a maximum altitude of three metres so that it doesn't require registration as an aircraft.
That enables it to sit on a cushion of air and travel at 80kph in any direction.
Other versions are being developed to dock with skyscrapers for rescues and for military use.
The crafts are powered by eight rotary engines, each driving an enclosed fan to produce lift.
It can still hover if one engine fails while a second failure “will lead to a survivable hard landing.”
Moller, which has been researching a variety of flying cars since the 1960s, is expecting the M200G to be available to buy from next year.
With only two simple hand operated controls, the craft will present a licensing and registration quandary for authorities because it doesn't actually travel on roads but is not an aircraft.
Initially, the flying saucer will cost around $146,000 but the price might fall further with mass production.
