The fuel-free aeroplane Solar Impulse has taken off from Chongqing in western-central China and is heading for Nanjing in the east. It is the sixth stint in a bid to fly around the world that began in Abu Dhabi, UAE on 9 March. Nanjing is about 200km from the coast, very close to Shanghai. The first Pacific leg would cover a distance of more than 8,000km.
