The President of the United States of America takes pleasure in presenting the Distinguished Flying Cross to Lieutenant A. J. Williams, Jr., United States Navy, for extraordinary achievements while participating in duly authorized aerial flights during the month of March 1928, in which he made a study of the action and best methods of control of a violently maneuvered airplane in inverted flight. These, and many other flights made by Lieutenant Williams in the interests of the advancement of the state of the art of airplane design and control, were attemded by exceedingly great personal risk of life but nevertheless they were voluntarily and willingly undertaken by him even though he was well aware of the danger involved. As a result of his flights and studies, he was able to evolve certain principles and to make practical appliation of them to the end that aerial maneuvers have been made safer and methods have been developed for more fully and accurately testing the capabilities of various types of airplanes. Lieutenant Williams has been one of the Pioneers of high speed flight and his distinguished feats in the air, development work, study and technical articles have all contributed to the knowledge and safety of aviation and have aided in keeping the United States well to the fore in the realm of the World’s aviation.
