From medical examination to licensed pilot -- this accounts for the first third of the book. The balance, and the more important part, discusses the airplane in the modern war, --procedure, tactics, strategy, U.S. program, the function of the pilot, of the gunner, of the crew, of the ground force, of the mechanics. Then the building of planes, the war time airport, the whole picture of maintenance. Civil aeronautics comes in for some discussion. The shipping of bombers -- through the author's own experience. In an appendix, details of how to join up, glossary, bibliography, etc. Excellent combination of sound basic fact and human interest.
