The Gossamer Condor is a human-powered aircraft designed by Dr. Paul MacCready and his team at AeroVironment. It made history in 1977 by becoming the first aircraft to achieve sustained flight powered solely by human effort. The aircraft features a lightweight structure and large wings, allowing it to glide efficiently. The Gossamer Condor was built as part of the Kremer Prize, which challenged inventors to create a human-powered flying machine. It successfully completed a flight of over 1 mile in 1977, demonstrating the potential of human-powered flight and inspiring future developments in aeronautics.
