America's youth builds and flies model planes on miniature flying fields. A member of the San Antonio Gas Model Club, which does its weekly flying at Kelly Field in the city of San Antonio in the southwestern U.S. state of Texas, proudly displays his amphibian model airplane, which has a six foot (1.8 meters) wing spread. When an earlier model crashed there was nothing left but one good wing. This young model enthusiast decided to build a new plane around it. He built an amphibian and turned out a perfect flying job. The plane is made of balsa wood covered with silk and waterproofing material. Like millions of other young Americans who make model building their hobby, this young man will be called upon to put his practical experience in aeronautics to use in the air-minded post war world
