Input: Question: How many pilots belong to the Finnish Air Force? Passage:Somersalo was educated at the University of Helsinki before studying natural sciences at the University of Jena. Based in Germany during the First World War he enrolled in the German Army as an officer in 1916, serving until the armistice. He would later claim that the war had been the death of old Europe and argued that one of its main positives was that it had "rescued our nation from the deadly, slimy embrace of a lothsome cuttlefish" in reference to Russia. He transferred straight to the Finnish Army and from 1920 to 1926 was the commander of the Finnish Air Force.
