A solar-powered airplane has begun its trans-Atlantic flight on the latest leg of its globe-circling voyage.
The Swiss-made Solar Impulse 2 took off from New York City early Monday morning.
Bertrand Piccard, who is piloting the aircraft, left at 2:30 a.m. from John F. Kennedy International Airport and will be landing in Seville Airport in Spain over three days later. It's the longest leg of the plane's journey so far in terms of distance.
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 trip began in March 2015 from Abu Dhabi, the capital of the United Arab Emirates. Stops were made in Oman, Myanmar, China and Japan.
