DAYTON, Ohio — A solar-powered airplane has taken off from the Ohio hometown of America aviation pioneers Wilbur and Orville Wright on the latest leg of its journey around the world.

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.

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 plane runs on stored energy at night.

Project officials say the layovers give the two Swiss pilots — Bertrand Piccard and Andre Borschberg — a chance to swap places and engage with local communities along the way so they can explain the project, which is estimated to cost more than $100 million.
