Plane sailing: Round-the-world solar aircraft touches down in China

The Solar Impulse (Si2), the solar-powered aircraft on a mission to fly around the globe without a drop of fuel, left landed in China Monday, completing the fifth leg of its journey. The aircraft, piloted by the Swiss project chairman Bertrand Piccard, left Mandalay, Myanmar last night, and headed for Chongqing in China. Leg five of the aircraft was a long one - about 1000 miles - and took roughly 19 hours.

Bertrand, from Albert, you are clear to proceed. Have a nice flight.

The plan of the project team is to make a brief stop then try to reach Nanjing on the east coast of China. This would set up the Si2 for the first of its big ocean crossings - a five-day, five-night flight to Hawaii. Capable of flying over oceans for several days and nights in a row, the single-seater Si2, which started its journey from Abu Dhabi in the United Arab Emirates (UAE) on March 9, will travel 20,000 miles around the world in 25 days.
