Solar-powered plane sets off on first round-the-world flight

Solar Impulse 2 took off from Abu Dhabi on Monday on the first leg of its quest to be the first plane to fly around the world fueled only by the sun's rays.

The solar-powered plane is expected to take 12 hours to reach its first pit stop, in Muscat, Oman, before flying to India, Myanmar, China and on to the U.S.

The 400-kilometer (250 mile) first-leg flight is part of a marathon 35,000-kilometer journey, which is expected to take as long as five months.

The potentially historic flight had been due to take off on March 1 but its departure was postponed because of concerns about the weather after strong dust storms created hazy conditions.

"We have had a lot of sandstorms in Abu Dhabi, and also a lot of wind, sea breezes, higher than the limit," said the team's meterologist Luc Truellemans in an interview posted on Twitter and YouTube.

By Monday morning, the skies had cleared sufficiently for takeoff, though there was a slight delay while technical checks were carried out, as pilot Andre Borschberg explained on Twitter.

But eventually the plane got off the ground, under the watchful eye of fellow pilot Bertrand Piccard, who will tackle the next part of the journey.


Monday's journey to Oman will be relatively short, compared to some of the longer legs, which will take up to five or six days and nights.

Borschberg and Piccard will spend a total of 500 hours behind the controls over the entire trip, taking it in turns in the tiny 3.8-square meter single-seater cockpit.

Before the takeoff, Piccard admitted the pair"had "butterflies in the stomach" at the thought of getting underway after working on the project for so long.
