Quote: Solar Impulse founders Bertrand Piccard (in pilot seat) and André Borschberg in Phoenix at the end of the first leg of the solar plane's historic cross-country trip. With not a drop of fuel, a solar-powered plane completed the first leg of its historic cross-country flight, a 19-hour trip from California to Arizona, touching down at Phoenix's Sky Harbor International Airport on Saturday (May 4) at 4:30 a.m. EDT (1:30 a.m. PDT). The solar-powered aircraft, named Solar Impulse, had taken off from Moffett Airfield near San Francisco, Calif., at 9:12 a.m. EDT (6:12 a.m. PDT) on Friday (May 3). Solar Impulse is the first aircraft capable of flying day and night without using any fuel. The plane relies solely on its solar panels and onboard batteries for power. During today's flight, the aircraft is expected to reach a cruising altitude of 21,000 feet (6,400 meters). [Images: Cross-Country Flight in a Solar-Powered Plane]
