Scientists believe in the near future a new kind of car that can not only drive on the road, but also fly in the sky will serve the people, it is called “flying-driving vehicle”.

Since the turn of the 20th century, there have been many hundreds of designs for flying-driving vehicles. And some of them have actually been built and flown. But “Transition” is the closest to people.

Transition was designed in 2006, and the first road and flight tests took place in 2009. Transition is designed to really be a general airplane, which can fold up(折叠)fully its wings, drive down the road and park in a single-car garage(车库).

Transition can climb to more than 3000 meters high. It can carry two people at speeds over 160 kilometers an hour in the air. And on the ground it can drive at highway speeds, about 113 kilometers an hour.

Scientists expect Transition to reach market at the end of 2012, at a price of around 25, 0000 dollars. Mr. Carl Dietrich says nearly 100 people have already signed up as buyers. He hopes to sell as many as 1000 a year in the near future.
