The car­plane has wings that unfold for flying－a process the company says takes one minute－and fold back up for driving.A runway is still required to take off and land.

　　The Transition is being marketed more as a plane that drives than a car that flies，although it is both.The company has been working with FAA to meet aircraft regulations，and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.

　　The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble from trying to find another mode of transportation to get to and from airports：You drive the car to the airport and then you're good to go.When you land，you fold up the wings and hit the road.There are no expensive parking fees because you don't have to store it at an airport－you park it in the garage at home.

　　The car­plane is designed to fly primarily under 10,000 feet.It has a maximum take off weight of 1,430 pounds，including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal(临界的)conditions.

　　The Transition's price tag：194,000.But there may be additional charges for options like a radio，a transponder or a GPS.Another option is a full­plane parachute.

　　“If you get into a very awful situation，it is the necessary safety option，”Gersh said.
