The global journey of Solar Impulse 2 began in Abu Dhabi in March 2015. It faced delays along the way, before attempting the most dangerous part of its journey: the flight over the Pacific Ocean, where there are few places to make an emergency landing.
Pilot Bertrand Piccard made the 62-hour, nonstop solo flight without fuel. Now three more stops in the United States remain.
The plane will then attempt to traverse the Atlantic Ocean on the last leg of its trip.
