     Terrafugia Company has said that its flying
car, named Transition, has successfully finished
a 37-second test flight.
     On March 5, 2009, at Plattsburgh International
Airport in New York. It was piloted by Phil Meteer,
the company's chief pilot.

                                                    
     Transition is a two-seat airplane that can take off and land at airports as well as drive on roads.
     The company said that the flying car can travel at speeds up to 115 mph for 450 miles in the air,
drive at highway speeds on the ground, and fold up (折叠) to fit in a garage (车库) 81 inches wide,
and 80 inches high.
     This could be used in hospitals to transport patients so as to avoid road traffic. It may start running
on wheels, and when it gets to traffic lights it can fly overhead the lights and keeps its way forward.
So it's good news to avoid traffic problem and the traffic accidents.
     But some people say this is a going airplane rather than a flying car, at least on the appearance.
Anyway, we are happy for scientific-technical progress, what a fantastical world in the near future!
