The Solar Impulse demonstrator aircraft, built to eventually show off the ability to fly through the night, completed its first flight on April 7 (it actually lifted off during a prior trial late last year, but the April 7 event is the formal first flight) in Payerne, Switzerland. The aircraft was airborne for 87 min. Here are scenes from the video released by Solar Impulse.
