The Flight of Helios

NASA's Helios aircraft, a solar-powered flying wing, is seen here at 10,000 feet near Kauai, Hawaii. With 14 electric motors and a 247-foot wingspan covered in solar cells, Helios demonstrated the potential for long-duration, high-altitude flight. This remotely piloted aircraft flew nearly a century after the Wright brothers' first flight.
