Transition flying car into 'beta test': Deliveries from 2011

In this case 'beta test' = new prototype

The makers of the Terrafugia Transition - the closest thing to a flying car yet built - say that flight testing of the initial "proof of concept" vehicle is now complete, and that the Transition has been shown to be a viable proposition. Terrafugia will now build a "beta test prototype", incorporating lessons learned by the first phase of flight tests. First customer deliveries are now expected in 2011.

The traffic round here's bloody terrible.

The Transition isn't a proper Jetsons-grade flying car. It can't hover or make vertical takeoffs/landings; it's noisy in flight; it isn't any more able to cope with poor visibility or congested airspace than a normal light aircraft. You can't use it to beat the rush-hour traffic and fly to your office in the city centre.

But the Transition is a successful "roadable aeroplane". It takes off, lands and flies like any other light plane, using small local airfields. On the ground, the pilot can press a button and in 30 seconds the wings fold up. The propellor is disconnected, and the Transition becomes a front-wheel-drive car with typical performance. It runs on unleaded, and will fit into a single-car garage. You only need a US "sport pilot" licence - significantly easier and cheaper to get than a normal private pilot's licence - to fly it.

"Successful" flight tests, but we're going to redesign it anyway

All this means that a Transition is a lot more useful than a normal light plane. You can get into it at home, drive to your local airfield, fly to another field near where you're going, land and then drive to the very door you want. Normally there'd be a lot more faff with cars, taxis etc at each end of the flight - and a need to find hangar space or a tie-down for the plane at the destination field. Unflyable weather is also a constant hassle for sport and private pilots; but the Transition can always resort to driving on the ground.

Also you can pick up a packet of Minstrels with your fuel.

So the Transition isn't a miracle hover-car: but it's still a very groovy idea. The design is evidently not ready for production, however, as the decision by Terrafugia to mothball the initial craft after 28 flights and build a new prototype makes clear. If only minor tweaks had been necessary, one might have expected modifications to the existing airframe and further flight trials.

"I would like to keep flying this Proof of Concept vehicle," says test pilot (and retired US airforce colonel) Bill Meteer, "but it makes sense to move on to the Beta Prototype."

The whole process of building the Transition has evidently been tougher than the Terrafugia team - mostly MIT engineers and flying enthusiasts - had hoped. Initial customer deliveries were originally expected this year, a forecast which has now slipped significantly. It's to be hoped that Terrafugia can stay afloat through the next two years before it starts collecting money from customers.

The company says that "with the sustained first flight buzz has come a substantial increase in airframe reservations for the Transition", but unlike some innovative transport companies Terrafugia doesn't spend the reservation deposits. They are held in a third-party account which the company can't touch, so that if Terrafugia goes out of business or can't deliver the promised Transition the customer is guaranteed to get his or her deposit back.

This shows admirable probity, but it does mean that Terrafugia needs to start delivering Transitions as soon as possible. ®
