Karl Berner - Luftwaffe "pilot"
 

Hello all
Does anyone have information about "potential pilot" of Luftwaffe named Karl Berner. Allegedly during 43. or 44. Karl landed at Gruda airfield near Dubrovnik and stayed at local house in Gruda for some period. After the war (70 or 71) he with his wife Wilma came to visit family where he stayed in that period.
He also regularly wrote letters and sent pictures to that family but unfortunately these were lost.
Unfortunately I don't have any more information.
Is there any information about this person
As always, thanks in advance.
