A solar-powered plane trying to fly around the world landed late Monday in Phoenix, Arizona to complete the latest leg of its journey.
The pilots of Solar Impulse 2 will next fly on a course toward New York before crossing the Atlantic Ocean for a stop either in Europe or Northern Africa.
Their ultimate goal is making it back to Abu Dhabi in the United Arab Emirates where the trip began in March 2015. The plane has also made stops along the way in Oman, Myanmar, China and Japan.
Organizers say they want to show the possibilities of clean energy technology, and that already they have demonstrated it can work.
Solar Impulse 2 has a 236-foot wingspan, longer than that of a Boeing 747. It is equipped with more than 17,000 solar cells that power propellers and charge batteries that store energy for night-time flight.
