This historical dictionary is on the US Air Force and antecedent organizations. The reference is based on lengthy research by Charles Bright and 57 military historians, air force officers, and aviation specialists. Over 1050 entries survey the major commands, air forces, staff services, bases, significant battles, events, campaigns, concepts, people, equipment, legislation and other characteristics. This reference has been developed as a tool for those who know the USAF and want to investigate different subjects further and for those with only slight knowledge who need a general base for exploring air force matters more fully. The dictionary is intended for libraries, for museums and special military collections and for all bookstores interested in the history of flight. The volume provides a preface with guidelines for using the dictionary, a short history of the US Air Force and its antecedents from 1907 to 1992. Entries are arranged alphabetically with bibliographical citations. They cover all the significant subjects of USAF history from a handful of men with flimsy balloons and flying machines to the earth-shaking aerospace giant. Cross references throughout the book help the reader have easy access to all the entries that are related or that appear under a different entry title.
