Carl Dietrich not just always dreamed of building a flying car, but did everything to make it true. On the way, he realized that he has to modify it, however. The pragmatic inventor ended up creating what he calls a “roadable aircraft”, a plane that folds up its wings on landing and takes to the highway. In 2010, after three years of development, his vehicle, the Transition, will be available to customers for $194,000.
Terrafugia, the Woburn, Massachusetts Company behind the Transition, began as an extracurricular activity for Dietrich while he was completing his Ph.D. in aeronautics and astronautics at MIT. Dietrich, 31, knew from the start that the odds were stacked against his project. Since the time of the Wright brothers, there have been more than 100 attempts to build drivable planes or flying cars. All have failed commercially.
"The basic problem is simple: A car is heavy, a plane is light," says Lionel Salisbury, publisher of the Roadable Times, a Web site devoted to chronicling flying-car attempts. "The two don’t go together well."
Dietrich’s early sketches envisioned a plane that would be driven rather than an automobile that took flight. At every step of the process, he was guided by the need to create something to be used in today’s world, not tomorrow’s.
So he and his team designed the Transition with regular car tires instead of aircraft tires. When the wings are folded up, the craft can park in a typical home garage, and it even runs on premium gasoline rather than aviation fuel. "We knew we could build it," Dietrich says. "The question was, ’Can we make money on it?’ The key was not to base the business plan around a market that is not real."
Transition’s design team studied the history of similar machines and the inventors who failed to bring their concepts to market. The most notable was Moulton "Molt" Taylor, a former Navy pilot who designed his first Aerocar in 1949, launched it in 1956 and produced a grand total of six vehicles.
Terrafugia concluded that the Aerocar failed because it was too difficult to convert from plane to car. "You had to unbolt the wings and reassemble them into a trailer," says Anna Mracek Dietrich, Carl’s wife and the company’s COO.
Terrafugia doesn’t lack for competitors. In Los Angeles, Icon Aircraft is currently marketing a towable light aircraft that is amphibious (price tag: $139,000). In Alvin, Texas, LaBiche Aerospace has developed a flying sports car, which is classified as an experimental aircraft, and is taking orders for the $175,000 kits. Milner Motors, a father-and-son team based in Vancouver, Wash. and Bethesda, Md., is working on a prototype for a drivable plane that it expects to sell for $450,000. Publicly traded Moller International (MLER) in Davis, Calif. has designed a personal aircraft that takes off and lands vertically. There are others as well, but Terrafugia appears to be further along than most in bringing its product to market.
Terrafugia plans to manufacture the Transition in-house for now, although the Dietrichs aren’t opposed to partnering with a larger manufacturer in the future. Meanwhile, they’re negotiating with the Federal Aviation Administration and the U.S. Department of Transportation to settle on a design that satisfies both aircraft and auto regulators. That doesn’t even begin to address the substantial insurance challenges.
The FAA gave Terrafugia a boost in 2004, when it relaxed structural and maintenance requirements for ultra-light planes by adopting the Sport Pilot and Light-Sport Aircraft Rule. This allowed experimental aircraft designers to push the technological envelope.
The Transition is powered by the same 100bhp engine on the ground and in the air. Terrafugia claims it will be able to fly up to 500 miles on a single tank of petrol at a cruising speed of 115mph with two people and their luggage onboard. It will also come with an electric calculator (to help fine-tune weight distribution), airbags, aerodynamic bumpers and of course a GPS (Global Positioning System) navigation unit.
Terrafugia Transition - First Flying Car
Anyone can drive it as a car; however, you will need a key code to make the wings unfold. You can only get this key code if you have a pilot’s license, so that’s good for safety’s sake.
In the next five years, Dietrich hopes to sell a few hundred Transitions, mostly to wealthy private pilots and professionals who need to make short but regular flights. As FSB went to press, Terrafugia had gathered 40 deposits and its order backlog totaled more than $8 million.
While the company doesn’t anticipate mainstream adoption of the Transition, Dietrich does expect an envy factor: "You see it in your neighbor’s driveway," he says, "and you realize that he has a freedom you lack."
