A solar-powered plane flew over the San Francisco Bay area on Tuesday (April 24). The flight was technically a test run to prepare for a planned cross-country trip in early May. On the first leg of the trip, the plane will depart from the Bay Area and head to Phoenix, Arizona.
This was not the first flight for the plane, but it was the lengthiest so far. It remained in the air for roughly sixteen hours.
The lightweight plane, owned by the Swiss firm Solar Impulse, has a wingspan of 208 feet (63 meters), and flew about 3,000 (914 meters) feet in the air above the Golden Gate Bridge.
The plane weighs approximately 3,500 pounds (1587kg) and runs completely on power from the sun drawn from 12,000 solar cells on the craft that send energy into batteries that power propellers running on four electric motors.
