MacCready Gossamer Penguin
The Gossamer Penguin was a solar-powered experimental aircraft created by Paul MacCready's AeroVironment. MacCready had built the Gossamer Condor in 1977 which won the Kremer prize for the first human-powered flight, and the Gossamer Albatross, a similar but larger aircraft.
