Switzerland's Andre Borschberg (R) and Bertrand Piccard (L), Solar Impulse founders and pilots, pose with  Prince's Albert II of Monaco (C) at the new Monaco Solar Impulse control center, on February, 10, 2015, in Monaco. The privately-financed project Solar Impulse hopes to achieve the first circumnavigation of the Earth by a piloted fixed-wing aircraft using only solar power. This circumnavigation is scheduled to begin in March 2015 in Abu Dhabi in the United Arab Emirates and to return there five months later.
