Solar Plane Finishes Trip Around The World

The solar plane has finally finished its journey after 16 months.  Learn more about the trip.  Here's an excerpt:

Solar Impulse 2 has completed the first round-the-world flight by a solar-powered aeroplane, after touching down in Abu Dhabi early on Tuesday.

The final leg of the feat, aimed at showcasing the potential of renewable energy, was a bumpy one, with turbulence driven by hot desert air leaving the solo pilot, Bertrand Piccard, fighting with the controls.

The plane, which has a wingspan wider than a Boeing 747 and carries more than 17,000 solar cells on its wings, began the circumnavigation in March 2015 in Abu Dhabi. It has since crossed both the Pacific and Atlantic Oceans using no fossil fuel and has spent more than 23 days in the air.

Speaking to the Guardian from the cockpit shortly before landing, Piccard said he was feeling emotional as he neared the end of the journey: “It is a very, very special moment – it has been 15 years that I am working on this goal.

“I hope people will understand that it is not just a first in the history of aviation, but also a first in the history of energy,” he said.
