Solar-Powered Plane Completes Historic Atlantic Crossing

Solar Impulse is closing in on trip around the world.

A smiling Piccard was greeted by his Solar Impulse partner, Andre Borschberg, as he exited the cockpit after spending 71 hours and 8 minutes inside the cockpit, cruising over the ocean at a speed of around 50 mph.

"The Atlantic is always the symbolic flight for all the means of transportation and today it becomes a symbolic flight for energy vision," Piccard told ABC News before he took off from New York City. "It is the first time an airplane flying solar -- that means with electric engines, zero emissions, zero fuel -- is attempting to cross this ocean from America to Europe, so it is extremely exciting for all of us."

The two pilots expect to complete their around-the-world journey this summer in Abu Dhabi -- where the voyage began in March 2015. They expect to have about three more flights before completing their circumnavigation of the globe.
