Taking advantage of new FAA regulations in the Light Sport Aircraft category, Terrafugia developed the Transition to provide pilots the convenience of a dual-purpose vehicle. Its unique design allows the Transition to fold its wings and drive on any surface road with a modern personal airplane platform. Once at the airport, the wings extend and the aircraft is ready for take-off. Both folding and extending the wings is done from inside the cockpit.

The Transition addresses head-on the issues private and sports pilots face: cost, weather sensitivity, high overall door-to-door travel time and a lack of mobility at destination.

To date, Terrafugia remains privately funded by a sophisticated group of accredited investors. The company is based just outside of Boston in Woburn, Massachusetts, USA.
