The United States’ Third Army Air Service, an organisation based in France and Germany immediately after the First World War, is shown here demonstrating Caquot Observation balloons and planes at an air show in Coblenz, Germany on the 26th of April 1919.
The area was occupied by France in the aftermath of the war, and in a sign of defiance of the occupation, the Germans living in the region began using the alternative spelling of “Koblenz” – which is the name used today.
The American organisation was disbanded in July of the same year.
