Solar-powered plane lands after round-the-clock flight
A solar-powered aircraft has landed safely in Switzerland after successfully flying through the night.
The test flight was a major step toward the makers' aim of circling the globe using the power of the Sun to fuel the plane.
The aircraft used super-efficient solar cells and batteries to stay in the air after the Sun's rays had faded.
The plane touched down at an airfield about 30 miles (50 km) from the Swiss capital Bern at 0900 (0700 GMT).
