I can imagine what fun my father and grandfather would have had with solar powered toys and kits if there had been such a thing when they were young. My dear father and loving grandfather both loved electronics and worked in the field. My dad was an electrical engineer, and though he didn't have toys like the ones pictured on this page when he was growing up, he used his creativity and interest in flight to design and make model airplanes. He worked for many years in the aeronautics department of a large company during the early years of the NASA space program when we were making history by sending men to the moon and doing many other space missions. He designed moving parts for some of the space missions including Apollo and Viking missions, as well as planes and jets.
