A solar-powered aircraft attempting a historic around-the-world journey completed its first leg Monday, landing in darkness in Oman after a flight of more than 13 hours from Abu Dhabi.A solar-powered aircraft attempting a historic around-the-world journey completed its first leg Monday, landing in darkness in Oman after a flight of more than 13 hours from Abu Dhabi.
The Swiss-made, single-seat plane — as light as a minivan but with the wingspan of a jumbo jet — left Abu Dhabi’s Al Bateen Executive Airport just as the sun was rising. It touched down in Oman’s capital, Muscat — more than 300 miles by air over desert and mountains — with its wings dotted by rows of lights.The Swiss-made, single-seat plane — as light as a minivan but with the wingspan of a jumbo jet — left Abu Dhabi’s Al Bateen Executive Airport just as the sun was rising.

“Confirmation: We’re down!” said the commentator on the mission’s official Web site. Applause broke out in the control room in Monaco.“Confirmation: We’re down!” said the commentator on the mission’s official Web site. Applause broke out in the control room in Monaco.
The plane is to leave early Tuesday on its next leg, across the Arabia Sea to Ahmedabad, India. The plane is to leave early Tuesday on its next leg, across the Arabian Sea to Ahmedabad, India.
The plane runs only on solar power and cuts through the air mostly silently on a battery charge. Its wings, spanning as wide as those of a Boeing 747, carry more than 17,000 solar cells that transfer energy to four electric motors that power the plane’s propellers.

Electric bikes followed the plane, the Solar Impulse 2, as it taxied for takeoff, to prevent the wings from touching the runway, the BBC reported.Electric bikes followed the plane, the Solar Impulse 2, as it taxied for takeoff, to prevent the wings from touching the runway, the BBC reported.
Solar Impulse founder André Borschberg flew the plane on the first leg of its 21,700-mile journey. He will trade off with fellow Swiss co-founder Bertrand Piccard during layovers.Solar Impulse founder André Borschberg flew the plane on the first leg of its 21,700-mile journey.

“After 16 years of a dream and 12 years of hard work, we hope it will work,” Piccard told the BBC after the plane took off.“After 16 years of a dream and 12 years of hard work, we hope it will work,” Piccard told the BBC after the plane took off.
Some legs of the 25-day journey, spread over five months, will entail five full days and nights of flying solo, such as when the plane crosses the Pacific and Atlantic oceans. It is due back in Abu Dhabi in late July or August.Some legs of the 25-day journey, spread over five months, will entail five full days and nights of flying solo, such as when the plane crosses the Pacific and Atlantic oceans.

The plane will stop at various locations around the world for the pilots to rest and do maintenance — and also to spread the message about clean, renewable technologies.The plane will stop at various locations around the world for the pilots to rest and do maintenance — and also to spread the message about clean, renewable technologies.

The plane’s cockpit, about the size of a telephone booth, is so cramped that it holds only one person. The pilot will not be able to stand while flying, but the single seat reclines for stretching and its cushion can be removed to access a toilet.The plane’s cockpit, about the size of a telephone booth, is so cramped that it holds only one person.

“We never feel alone in the cockpit, though,” Piccard told the BBC. He pointed out that flight pioneer Charles Lindbergh also flew in a small cockpit.“We never feel alone in the cockpit, though,” Piccard told the BBC.

Piccard said millions of people around the world were behind the prototype effort to find a more sustainable and cleaner alternative to aircraft powered by fossil fuels.Piccard said millions of people around the world were behind the prototype effort to find a more sustainable and cleaner alternative to aircraft powered by fossil fuels.

The Solar Impulse 2 weighs just over 5,000 pounds, about as much as a minivan or a mid-size truck. An empty Boeing 747 jet weighs about 400,000 pounds. Solar cells line the top of the Solar Impulse’s wings, and energy-dense lithium-ion batteries sustain it during nighttime flying.The Solar Impulse 2 weighs just over 5,000 pounds, about as much as a minivan or a mid-size truck.

The best speed for the plane is about 28 mph, the pilots told the Associated Press. The slow speed means the journey’s legs will take several days and nights of nonstop flying.The best speed for the plane is about 28 mph, the pilots told the Associated Press.

Borschberg has been practicing yoga and Piccard self-hypnosis to get ready for the historic endeavor, the AP reported. They aim to rest a maximum of 20 minutes straight, repeating the naps 12 times over a 24-hour period — akin to how a lone around-the-world yachtsman sleeps in snatches.Borschberg has been practicing yoga and Piccard self-hypnosis to get ready for the historic endeavor, the AP reported.

Goggles will flash lights to wake the pilot up, the AP said, and armbands placed underneath the flying suit will buzz if the plane isn’t flying level.Goggles will flash lights to wake the pilot up, the AP said, and armbands placed underneath the flying suit will buzz if the plane isn’t flying level.
The aircraft will reach an altitude of about 28,000 feet during daytime hours to catch the sun’s rays. When flying over oceans at night, it will drop to about 5,000 feet.The aircraft will reach an altitude of about 28,000 feet during daytime hours to catch the sun’s rays.

After two stops in India, the plane will head to China, where it will stay for a month until the days are longer so more of the sun’s energy can be tapped. It is to stop in Myanmar, Hawaii, Arizona and at New York’s John F. Kennedy International Airport. The path across the Atlantic will depend on the weather and could include stops in Southern Europe or Morocco.

People can follow the flight on Solar Impulse’s Web site, tracking the plane’s battery status, energy consumption, location and path, as well as how much the pilot has slept and how much food and water he has left. There is also a live feed of the plane’s control room, with occasional footage from the cockpit.
