On 8 March 2010, the solar-powered aircraft Solar Impulse (HB-SIA prototype) had its maiden flight at the military airport in Payerne, Switzerland.
The prototype, with the wingspan of a Boeing 747 and the weight of a small car, started to a two-hour test flight to examine whether the plane can keep a straight trajectory. The Solar Impulse project aims to circumnavigate the world with an aircraft powered only by solar energy.
