The Army and the Navy need scale models for training pilots, for airplane spotters, for serial gunner training, and so on. Through schools and colleges and civilian organisations the demand has gone out for more scale models. This book -- and its supplement -- contain official instructions for building 60 model planes, official photographs, assembly plane, profile and silhouette views, basic data on make, speed, size, function, etc. The book carries the step by step instructions with progressive photographe; the supplement has the actual scale plans. A salesable item for adults interested in the subject, and for boys and -- yes -- girls, not only in the schools where the courses are given, but everywhere.
