The Solar Plane That Will Circle the Globe

Prototype plane Solar Impulse, with pilot André Borschberg onboard, flies at sunrise above Payerne’s Swiss airbase on July 8, 2010.

For the prototype’s grand finale, Borschberg and project partner Bertrand Piccard traded off legs on a five-part journey across the U.S. starting in May 2013.

Since then the team has focused on building the plane’s successor, Solar Impulse 2, which has been 10 years and about $150 million in the making.
