Like the robot maid, the flying car is part of our 'Jetsons'-promised future that has yet to materialize.

But that could change soon. Last month, the National Highway Traffic Safety Administration granted the Transition Roadable Aircraft a series of special exemptions, effectively making the plane-car hybrid street-legal.

The Transition was developed by a team of MIT-trained researchers for the company Terrafugia. The two-seater is able to morph from a car to a plane in about 30 seconds. It also runs on regular unleaded gas, instead of more expensive rocket fuel.

The flying car will run for about $250,000. Terrafugia estimates it will be available to the public by the end of 2012. Read on to see the Transition Roadable Aircraft in action.
