A mysterious aspect of the history of airfields and landing strips functioning in the vicinity of Bochnia is the period of World War II, when the German Luftwaffe established a large grass-surface airfield on the fields of Proszówki. This was connected with a decision made in 1940 by the Luftwaffe command to implement a program for developing a network of military field airfields.
Among the aircraft that landed there were transport Junkers Ju-52s, and according to unconfirmed oral accounts from residents, night fighters also landed there, hunting for aircraft making supply drops for the Home Army. German airmen were quartered in a distinctive villa with a turret, standing by the road from Szarów to Proszówki.
