Dr. MacCready was also successful in designing and building a solar-powered plane, and the flying Pterodactyl featured in the IMAX movie "On the Wing." Dr. MacCready is the founder and President of Aerovironment in Monrovia, California, where his team of engineers have, among many other things, designed the solar-powered car "Impact" for General Motors. In addition to his scientific and technological achievements, he has actively supported the skeptical movement for many years, as well as promoted scientific education for all ages.
