This book, the first to be published in English presenting a complete historical record of every type of military aircraft produced in Germany between 1914 and 1918, would not have been possible without the cooperation and assistance of many enthusiasts whose help is gratefully acknowledged.
The greater part of the main text has been vetted by that painstaking historian Herr Egon Krucgcr who also provided so much of the additional material in this revised edition. For any mistakes that may remain the authors accept full responsibility. Much of the data in the appendices has been compiled from the files of Egon Krucgcr and Peter M. Grosz, both of whom contributed many photographs and offered every cooperation.
