The Foggiani The bombing effort continued to grow in spite of the disaster to the Italian ground forces at Caporetto. In late 1917, due to the lack of suitable training facilities in the United States, a contingent of some 500 Americans were sent to Foggia, Italy, to learn military flying. After completing their training, the new pilots were commissioned in the Army Air Service, and the majority of them were sent to France to serve with the American Expeditionary Force.
