Looking here, it appears that The Black Fox was shot down over Austria on July 16, 1944. Sounds like a match. (A Black Fox II went down over Germany in late 1944).
For Flak Man, it shows
01/20/45 Taxi Accident
03/19/45 Landing Accident

My grandfather was one of the crew members. They received the medal for the mission in the Flak Man. The same crew was shot down on July 16 (the next day) in the Black Fox. One member was killed, the rest were prisoners until the end of the war.
