Solar-Powered Airplane Completes First International Flight
liqs8143 writes "Solar Impulse, a fully solar-powered airplane, has completed its first international solar-powered flight. After a flight lasting 12 hours 59 minutes at an altitude of 12,400 feet, using no fuel and propelled by solar energy alone, Solar Impulse HB-SIA landed safely in Brussels, Switzerland. After the landing, company co-founder Bertrand Piccard said, 'Our goal is to create a revolution in the minds of the people . . . to promote solar energies — not necessarily a revolution in aviation.' Compared with 2003, energy efficiency has increased from 16 to 22 percent. And the cells are now half as thick. The project has a total cost of $88 million, which is funded by mostly-Swiss partners and public donations."
Switzerland to Belgium. So it wasn't just a hop across an adjacent border. And, as the summary says, they were in the air for almost 13 hours.

If they had a helicopter that hovered for 13 hours at such a low speed it would be even more impressive.
What, like a party balloon?
I'm not impressed. Solar planes have been in existence for a while. http://www.nasa.gov/vision/earth/technologies/solarFarm.html I really won't be impressed until it can carry cargo or passengers.
Actual flight path in title. Approx 660km @ 50km / hr, with cleared airspace due to special needs. See http://www.solarimpulse.com/blog/2011/05/13/all-lights-at-green/ Herzliche Glückwünsche to the team.
