This book is a chronological account of the establishment of Naval Reserve Aviation and its growth and development before World War II. It is a comprehensive history of Naval and Marine Corps Reserve Aviation - a documentation of the significant events in that history, together with many which would fall under the category of trivia. It is an attempt to illustrate what the Naval Aviation Reserve was all about, and to capture some of the flavor of the earlier days of aviation. The book, Volume I of a series on Naval and Marine Corps Reserve Aviation, may stir the memories of some of those people directly involved in these activities during the period covered. It should also prove interesting to others who might have an interest in the Naval Air Reserve and/or in early aviation.
