Solar-powered plane wraps first leg of flight across U.S
(Reuters) - The flight from San Fransisco to Phoenix took 18 hours and 18 minutes on Saturday - and didn't use a drop of fuel.
A solar-powered airplane that developers hope eventually to pilot around the world landed safely in Phoenix on the first leg of an attempt to fly across the United States using only the sun's energy, project organizers said.
The plane, dubbed the Solar Impulse, took 18 hours and 18 minutes to reach Phoenix on the slow-speed flight, completing the first of five legs with planned stops in Dallas, St. Louis and Washington on the way to a final stop in New York.
The spindly-looking plane barely hummed as it took off Friday morning from Moffett Field, a joint civil-military airport near San Francisco.
It landed in predawn darkness at Sky Harbor International Airport in Phoenix, according to a statement on the Solar Impulse's website.
The flight crew plans pauses at each stop to wait for favorable weather. It hopes to reach John F. Kennedy International Airport in New York in about two months.
Swiss pilots and co-founders of the project, Bertrand Piccard and Andre Borschberg, will take turns flying the plane, built with a single-seat cockpit. Piccard was at the controls for the first flight to Arizona.
The lightweight carbon fiber Solar Impulse has a wingspan of a jumbo jet and the weight of a small car and from a distance resembles a giant floating insect.
The plane was designed for flights of up to 24 hours at a time and is a test model for a more advanced aircraft the team plans to build to circumnavigate the globe in 2015. It made its first intercontinental flight, from Spain to Morocco, last June. Continued...
