Solar-powered plane takes off

A Swiss solar-powered plane has taken off for its first international flight.









The Solar Impulse team behind the project plans to fly the experimental aircraft to Belgium and France.



The single-seater prototype took off from Payerne airfield in Switzerland at 6.40am and is expected to reach Brussels airport by nightfall.



The plane with the wingspan of a Boeing 777 made its 2009 maiden flight in Switzerland and further tests have all taken place there.



The flight across France, Luxembourg and Belgium poses a fresh challenge as it requires navigation across international air traffic networks.
