Solar Impulse 2: Test flight carried out in Switzerland
A solar-powered plane that will attempt to fly around the world in 2015 has completed its inaugural flight after taking off in Switzerland.
Solar Impulse 2 is a larger, upgraded version of the aircraft that flew across the United States last year.
Project leaders Bertrand Piccard and Andre Borschberg say they want to push the boundaries for alternative energy.
