DAYTON, Ohio AP -- A solar-powered airplane has landed in Pennsylvania, about 17 hours after it took off from the Ohio hometown of America aviation pioneers Wilbur and Orville Wright.
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.
The plane had a five-day trip from Japan to Hawaii 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.
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.
