Solar-powered plane's latest leg: Oklahoma to Ohio

TULSA, Okla. — A solar-powered airplane that landed in Oklahoma last week is headed to Ohio on the latest leg of its around-the-world journey.

The Swiss-made Solar Impulse 2 took off from Tulsa International Airport about 5 a.m. Saturday with a destination of Dayton, Ohio. The flight was expected to take about 18 hours.

The aircraft's most recent journey came on May 13, when it traveled from Phoenix Goodyear Airport in Arizona to Tulsa in just over 20 hours. The plane was expected to make at least one more stop in the United States before crossing the Atlantic Ocean to Europe or northern Africa.

The globe-circling voyage began in March 2015 from Abu Dhabi, the capital of the United Arab Emirates, and made stops in Oman, Myanmar, China and Japan.
