A solar-powered plane which is circumnavigating the earth landed in New York City Saturday after flying across the United States.

The Solar Impulse 2 (Si2), made in Switzerland, has been on its global journey for more than a year, including nine months in Japan for battery repair. Its flight across America began in late April, and ideal flight speed is just 28 mph — the final leg from an airport north of Philadelphia into NYC took nearly five hours — though top speed in the midday sun is roughly double that.
