A pioneer in aviation, Paul MacCready designed the first human-powered airplane, the first piloted, solar-powered airplane, the first life-size flying replica of a giant pterodactyl, and a pioneering solar-electric car. MacCready's firm, AeroVironment, is at work on the Black Widow (transparent model prototype in MacCready's hand), a remotely controlled plane capable of flying 40 mph for up to 20 minutes. Zipping along at treetop level, the 15-cm-long, 58-gram Black Widow could spot details missed by even the sharpest satellite cameras. AeroVironment , Simi Valley, California.
