DUBENDORF, SWITZERLAND - NOVEMBER 06: Engineers inspect of one of the four propellers of the The Solar Impulse airplane after a day on the airfield performing engine tests on November 6, 2009 in Dubendorf, Switzerland. After five years of research, modelling and simulation training the Solar Impulse prototype with a 63.40 metres wingspan aircraft, registered as HB-SIA, is performing engine tests. The Solar Impulse project aims to circumnavigate the world with an aircraft powered only by solar energy.

An aircraft dubbed 'Solar Impulse', HB-SIA prototype, is rolled out of a hangar for an initial series of stationary tests involving engines and electromagnetic interference on November 6, 2009 in Duebendorf aerodrome near Zurich. The aim of the wasp-shaped prototype, with wingspan of a jumbo jet, is to test the feasibility of a complete flight sequence over two days and one night under solar energy power only and pave the way for a second aircraft to attempt a round the world flight in five stages set for 2012.
