Swiss "Solar Impulse 2" pilot Bertrand Piccard, right, and his partner Andre Borschberg smile at a hangar in Nanjing city, east Chinas Jiangsu province, 30 April 2015. The pilot who will attempt a record flight over the Pacific in a solar-powered plane played down the risks on Monday (4 May 2015), describing the mission as a journey of self-discovery. The Solar Impulse 2 and Swiss pilot Andre Borschberg are waiting in the eastern Chinese city of Nanjing for weather conditions to allow the most challenging leg of a landmark attempt to circumnavigate the globe in a plane powered by the sun. "We have a lot of measures to mitigate the risk, " Borschberg told reporters. "It's an adventure, but I see this as an inner voyage. "It's a great opportunity to discover myself." The 8, 500 kilometre (5, 270 mile) flight from China to the US state of Hawaii is expected to take five to six days non-stop, with only a single pilot. If it succeeds it will be the longest ever flight in a solar-powered plane. Organisers originally said the aircraft could take off Tuesday, but a spokeswoman said the earliest possible departure was now Saturday.
