Solar Impulse 2 has landed in Hawaii on the 12th leg of its 35,000 km flight around the world — powered entirely by 70,000 onboard solar cells and manned by intrepid pilots Bertrand Piccard and Andre Borschberg. Check out the great photos and video

The solar-powered prototype plane, with a wingspan wider than a 747, and its Swiss pilots have set a batch of records:

• world’s longest nonstop solo flight (in hours)
• distance covered and the time spent in the air – 118 hours
• manned, solar-powered flight
• solo, un-refuelled journey

The next leg of the trip is four days (and nights) from Kalaeloa Airport (on Oahu) to Phoenix; then on to New York City; an Atlantic crossing and back to Abu Dhabi where the flight originated. Those crafty Swiss!
