German test pilot Markus Scherdel steers the solar-powered Solar Impulse HB-SIA prototype airplane. The propeller plane, with a 61-metre 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. The flight follows six years' work by 50 engineers and technicians led by Swiss adventurer Bertrand Piccard on the so-called Solar Impulse project.
