太阳能飞机首次挑战环球之旅

　　A Swiss solar-powered plane took off from Abu Dhabi early Monday, marking the start of the first attempt to fly around the world without a drop of fuel.

　　Solar Impulse founder André Borschberg was at the controls of the single-seater when it took off from the Al Bateen Executive Airport. Borschberg will trade off piloting with Solar Impulse co-founder Bertrand Piccard during stop-overs on a journey that will take months to complete.

　　The Swiss pilots say their aim is to create awareness about replacing "old polluting technologies with clean and efficient technologies."
