The Solar Challenger is an incredible piece of aviation history-truly ahead of its time in showcasing the potential of solar energy in aviation. Its design, built on the successes of the Gossamer Albatross and Gossamer Penguin, shows how visionary engineers like Paul MacCready pushed the boundaries of what was possible with renewable energy and flight.
The fact that it completed a 163-mile journey across the English Channel without the need for reserve batteries is a testament to both the efficiency of its solar panels and the ingenuity of its lightweight design. The challenge of staying aloft for over 5 hours on just solar energy is remarkable, especially considering the constraints of that era's technology.
It's also fascinating that this was during the early '80s, when solar technology was still in its infancy, and yet it was enough to power an aircraft across significant distances. Having it in the Smithsonian today means it's preserved as a key milestone in the development of solar aviation.
