The Solar Impulse 2 (foreground), a solar powered plane, sits on the tarmac after it landed at Nagoya airport in Japan June 1, 2015. The solar-powered plane, which is attempting a round-the-world flight, will cut short the seventh leg of its 35,000-km global (22,000-mile) journey, landing in Nagoya, western Japan, due to bad weather.
