MOUNTAIN VIEW, Calif. (AP) - A solar-powered airplane is preparing to leave California for Arizona to continue its journey around the world.
The Swiss-made Solar Impulse 2 will take off from Mountain View before dawn Monday for what should be a 16-hour flight to Phoenix.
Swiss pilot Andre Borschberg will be at the helm of the plane that began circumnavigation the globe last year using only energy from the sun.
Borschberg's co-pilot, Bertrand Piccard, also of Switzerland, made the three-day trip from Hawaii to the heart of Silicon Valley, where he landed last week.
The crew was forced to stay in Oahu for nine months after the plane's battery system sustained heat damage on its trip from Japan.
The aircraft began its voyage in March 2015 from Abu Dhabi, the capital of the United Arab Emirates and made stops in Oman, Myanmar, China and Japan.
