KAPOLEI, Hawaii - After some uncertainty about the weather, the Swiss-made Solar Impulse 2 airplane has taken off from Hawaii as it continues its journey around the world.

The aircraft is heading to California as part of its circumnavigation of the globe using only energy from the sun. Its departure was delayed briefly Thursday by the wind.

The plane took off in March from Abu Dhabi, the capital of the United Arab Emirates.

The crew landed on Oahu last July but was forced to stay in the islands after the plane's battery system sustained heat damage on its trip from Japan.
