Paul MacCready builds the first solar-powered aircraft, which he calls the Solar Challenger. To prove its viability, he flies it from France to England across the English Channel. The aircraft is powered by over 16,000 solar cells mounted on its wings, which produce 3,000 watts of power. [US Department of Energy, 2002 pdf file]

The “Pathfinder Plus,” a solar-powered, remotely piloted aircraft upgraded from a previous version (see August 6, 1998), flies two successful test runs. The first demonstrates its use as a high-altitude platform for telecommunications and the second shows its ability as an aerial imaging system for coffee growers. The Pathfinder is capable of staying aloft for weeks or even months. Its wings are covered in solar arrays that power most of the craft’s electric motors, avionics, communications, and other electronic systems, and it has a battery-powered backup system.
