Da Vinci's Flyer Comes to Life

Discovery News: Leonardo da Vinci's flying machine really does fly! Angelo D'Arrigo, an expert on hang gliders, flew a working model based on the 500 year old drawings by Leonardo da Vinci. The problem da Vinci faced was one of materials not design. When modern light weight materials were used to make the model, "We ended up with a glider that looked like the skeleton of some giant pterodactyl, " D'Arrigo said. And it flew perfectly. The flying machine, called the Piuma, or feather, carried D'Arrigo's full weight in tests done at the Fiat car company's "wind tunnel".
