Solar Impulse takes off

Solar Impulse's CEO and pilot, Andre Borschberg, steers the solar-powered HB-SIA prototype airplane after it takes off for its first night flight attempt at Payerne airport, Switzerland, on July 7.

The propeller plane, with a 200-foot wingspan, is powered by four electric motors and designed to fly day and night by saving surplus energy from its 12,000 solar cells in high-performance batteries.
