Solar Plane

The Solar Impulse plane sits on the tarmac early in the morning before takes off on a multi-city trip across the United States from Moffett Field NASA Ames Research Center in Mountain View, Calif., Friday, May 3, 2013. Solar Impulse, considered the world's most advanced solar-powered plane, will stop for seven to 10 days at major airports in each city, so the pilots can display and discuss the aircraft with reporters, students, engineers and aviation fans. It plans to reach New York's Kennedy Airport in early July — without using a drop of fuel, its creators said. (AP Photo/Tony Avelar)
