Shanghai: Solar Impulse 2 landed early today in China, the world's biggest carbon emitter, as it completed the fifth leg of its landmark circumnavigation of the globe powered solely by the sun.

With pilot Bertrand Piccard at the controls, the revolutionary plane landed in Chongqing airport at 1:35 am (local time) after a 22-and-a-half hour flight from Myanmar, its vast wingspan lit up by rows of led lights.
