A glider-like aircraft, weighing about as much as a medium-size car, has completed the first night flight propelled only by solar energy, according to Reuters.
Organizers say the flight’s success shows the potential of renewable energies and clean technology.
The aircraft used super-efficient solar cells and batteries to stay in the air after the sun had set.
The plane touched down at an airfield about 30 miles from the Swiss capital of Bern after being in the air for 26 hours.
