Aviation Section Aviation Mechanic Patch
This is an insignia patch worn by aviation mechanics of the U.S. Army Signal Corps, Aviation Section during World War I. On May 24, 1918, President Woodrow Wilson transferred the Aviation Section from the Signal Corps to the newly established U.S. Army Air Service. The U.S. Army Air Service was a forerunner of today's United States Air Force. (U.S. Air Force photo)
