by Edward Radlauer, published 1974
A slim book aimed at juvenile audiences, consisting of a variety of color photos with brief captions. Shown are a hot-air balloon, a hang glider, a sail plane, a biplane pylon racer, a gyrocopter, AT6/SNJ pylon racers, a free-flight "old timer", and other model planes, and inexplicably, a "flying person" (a pole vaulter!).
8¼" x 9¾" Hardbound, 32 pages, this last remaining copy is in poor condition, ex-library copy, but usuable
