Sergeant Sol E. Hutton served with the U.S. Army Air Service in Italy during World War I, where he worked with Caproni on aircraft construction. The collection contains items related to the U.S. Air Service program to build Caproni Ca.44 (Military Ca.5, Ca.600) aircraft at the end of the war.

Historical Note

The materials in this collection relate to a project in which one hundred (100) mechanics and officers from the United States Army Air Service were instructed on construction of the Caproni Ca.44 (Military Ca.5/Ca.600) aircraft. The group was primarily comprised of members of the 10th Company, 3rd Motor Mechanics.

The majority of the company was sent to the Caproni factory in Taliedo, Italy in August 1918 under Captain J. A. Short. These men received instruction on aircraft assembly and began to build biplanes under Sergeant Charles H. Cooper. A contingent of twenty-four (24) men was stationed at the Fiat Factory in Turin, Italy under Captain J. S. M. Eley from August to October 1918, then relocated to the Isotta-Fraschini plant in Milan. These men received instruction in motor work. Sergeant Sol E. Hutton served with several other men at Taliedo to document technical data and draft reports on the work.

The Caproni Ca.44 was part of the Ca.5 model series of biplane bombers and is often known as the Caproni Ca.600 due to its three (3) engines producing 600HP. The American project to build these models produced only five (5) complete planes due to the armistice in November eliminating the immediate need for more.
