A solar-powered airplane on a journey around the world has landed in California, completing a risky, three-day flight across the Pacific Ocean from Hawaii.

Pilot Bertrand Piccard landed the Solar Impulse 2 in Mountain View, south of San Francisco, at 11:45 p.m. Saturday following a 62-hour, nonstop flight without fuel.

The aircraft started its journey in March 2015 from Abu Dhabi, the capital of the United Arab Emirates, and made stops in Oman, Myanmar, China and Japan. The plane is attempting to circumnavigate the globe to promote clean energy and the spirit of innovation.

The trans-Pacific leg is the riskiest part of the plane's global travels because of the lack of emergency landing sites.
