America's youth builds and flies model planes on miniature flying fields. This young American builds various types of model planes, with different types of wing construction in order to conduct a study of wind resistance. The planes are made of balsa wood covered with silk and waterproofing material. The experience and knowledge of aeronautics he gains in these experiments will be put to good use in the air-minded post war world. Courses in aeronautics have already been added to the curriculum in many U.S. schools
