During the twentieth century, civil and military aviation has played a prominent role in the history and development of Arizona. Commercial operators have exploited the advantages offered by aircraft to overcome its unique challenges of geography and climate. By virtue of Arizona’s dry climate and excellent storage facilities, as well as its clear air and wide open spaces in the Southwest (some might say “Old West”) area of the continental USA, a wide variety of military aircraft have been based or stored there through the years. The list of military aircraft types that made up the tapestry of Arizona aviation is as extensive as the list of legendary figures who have contributed to its amazing history. While most of the military aircraft types no longer grace the airspace over Arizona, many can be viewed in their former splendor as they stand as gate guards; museum exhibits, or as they stand mothballed in the “Boneyard.” This booklet provides a comprehensive guide to where these aircraft can be found. Finally, the descriptions of the recovery, restoration and preservation efforts stand as a tribute to the many volunteers who have devoted time, energy and financial support to ensure this rich heritage is preserved.
