Solar plane on global trip headed to Oklahoma from Arizona

(AP) — A solar-powered airplane that landed in Arizona last week after a daylong flight from California is headed to Oklahoma next on the latest leg of its around-the-world journey, project officials announced Wednesday.

The Solar Impulse 2's wings, which stretch wider than those of a Boeing 747, are equipped with 17,000 solar cells that power propellers and charge batteries.

The crew was forced to stay in Oahu, Hawaii for nine months after the plane's battery system sustained heat damage on its trip from Japan.
