Solar plane soars from Hawaii to California

A solar plane on a round-the-world journey has reached the point of no return over the Pacific Ocean after departing Hawaii, and now it's California or bust.

The plane was cruising over the cold northern Pacific late Thursday at about 6,000 meters with a nearly-full battery as night descended, according to the website that's documenting the journey of Solar Impulse 2.

After some uncertainty about winds, the plane took off from Hawaii and was on course to land in Mountain View, California, in about three days. The crew that helped it take off was clearing out of its Hawaiian hangar and headed for the mainland for the weekend arrival.
