Solar Impulse aims for Pennsylvania

1 hour ago
The sun-powered aircraft Solar Impulse has taken off from Dayton, Ohio, on a 750km flight to Lehigh Valley in Pennsylvania.

Mission controllers expect the 72m-wingspan, electric plane to complete the stage in about 17 hours.
The aircraft took off from Dayton International Airport just after 04:00 local time (08:00 GMT). Getting to Lehigh Valley will position the project to make its entry into New York in the coming days.
The "Big Apple" is set to be the base for Solar Impulse as it waits for a weather window to fly the Atlantic. Deciding when to cross the ocean will be a tricky decision. The slow-moving, ultra-light plane needs benign winds, and the team concedes that the right conditions may not present themselves for several weeks.
