It was a standard practice for markers to be placed at a crash site when a successful or experienced pilot was killed. These markers often consisted of a propeller blade and spinner. This photograph shows the grave of Hauptmann Erwin Aichele of Stab I.Gruppe / Jagdgeschwader 51 (JG 51) who was killed on 29 July 1940 during operations over the English Channel.
