China's solar powered UAV soars high into the sky

An undated photo shows a solar powered unmanned aerial vehicle, designed by China Academy of Aerospace Aerodynamics, flies during a test. The UAV, with a wingspan of more than 40 meters, is a long-endurance, high-altitude aircraft system that has a broad application prospect. The solar powered aircraft Solar Impulse II landed in western India on the night of March 10, 2015, completing the second leg of its historic round-the-world trip. The Solar Impulse II also plans to make stops in China. [Photo/people.cn]
