Experimental aircraft « Solar Impulse » with pilot Andre Borschberg onboard flies at sunrise above Payerne’s Swiss airbase on July 8, 2010 during the first attempt to fly around the clock fuelled by nothing but the energy of the sun. The solar powered aircraft was flying in circles high over Switzerland at first light well on its way to completing a historic round the clock flight. TOPSHOTS AFP PHOTO / FABRICE COFFRINI
