Sun-powered aircraft, Solar Impulse Two, has successfully landed in the US state of Pennsylvania on the latest leg of its journey around the world.
The Swiss-made single-seat airplane completed its 750-kilometer flight, from the US city of Dayton, in around 17 hours. The journey was the thirteenth leg in a historic quest that started in the UAE last year to fly around the globe without a drop of fuel. On its next round, the Solar Impulse is scheduled to fly to New York on May 30.
