Good morning Gentlemen,
in WW1 balloon kills counted as aerial kills. The top Belgian ace Willy Coppens would not have been an ace at all without his balloon kills.

In WW2 balloon kills were more often counted separately, the top ace of that profession being Mr. Baljasnikov.

I agree with Johannes and prefer to indicate WW2 balloon kills as
score(+balloon kills)
in my notes.
I suppose Beisswenger claimed his unconfirmed kill early in his career ?
Kind regards,
Michael
