Daniel Bierofka, callsign Wetterhahn, was a Belkan ace of the Belkan Air Force.[1]


As the Allied Forces commenced an attack on the Futuro Canal as part of Offensive Campaign No. 4101 during the Belkan War, Bierofka was tasked with attacking the 3rd Osean Naval Fleet to prevent them from breaking through the canal. Searching for an opening in the fleet's defenses, he was shot down by Galm Team, but survived the encounter.[2]

After the war he left the Air Force and became an automobile salesman.[3]
