After developing a string of inventions—including a linear-tracking phonograph, a forerunner of the sonogram, and one of the first prototypes for cellphone earpieces—Elwood Norris, a small-plane pilot, turned to the personal flying machine because, he says, “Everybody I have met seems to have this dream to get off the ground and defy gravity.” Norris claims his Henderson, Nevada-based AirScooter Corp. will have its first production machines on the market by early 2003, at a likely price of $25,000 to $50,000—somewhere between the cost of a well-equipped Ford Explorer and a Lincoln Navigator. And, he promises, you can learn to fly it in an hour.
