9、would threaten the growth of world air travel.The International Air Transport Association estimates there will be about 650，000 short of new pilots in the world over the next 20 years, and that the airline traffic will nearly double during that same period.The plane, which is expected to carry up to
10、 four passengers, would have a wing span of roughly 11 meters and would weigh only 900 kilograms.It would use vertical takeoff and landing technology, which means the plane can land vertically, meaning it can be landed in more places.Developers hope the prototype (原型) will be able to fly up to 698 k
11、ilometers, which is the distance between London and Germany.The plane would be ideal for travelling between islands as travellers wouldnt need to worry about changing from commercial flights to boats, taxis or car rides.Oliver Dlouhy, CEO and CoFounder of K said, “The Zuri project represents a direc
