Two men who speak with the authority of personal experience and present achievement (Arnold is chief of Army Air Forces and Eaker is with U. S. Army Bombing Command, English High Command) present a primer of the responsibilities, challenge, sacrifice, opportunity and life of army flying. Both pre-war and post-expansion period are featured, so as to give a balanced picture of immediate conditions and probable post war conditions. They show what are the elements that go to make good flyers -- and why. What are the tests to which all student flyers are subjected and why. Then they discuss each step in a model military career, with sage advice on how to establish a reputation for efficiency and intelligence, how to approach certain personal problems, marriage, handling of enlisted men, etc. Early training years -- middle years of staff and command -- essential non-flying tasks -- administration -- discipline -- morale. Than the waning years. The importance of keeping up outside civilian contacts throughout. The opportunities of the junior flyer, with available special courses. Finally, a section on air warfare, on the team and the crew set-up, on training, strategy and tactics. A book that should be valuable to those in the service -- as well as to aspirants. But not a correspondence course in tabloid form.
