It mattered to Popkin and Brown. The controversy was rather heated back
then,
because many felt that no pilot was good enough to kill MvR - while Allied
pilots felt that no denizen of the mud could have possibly done it. The
wounds
show upward travel, which mades the mystery somewhat less mysterious...

MvR was undoubtedly an excellent pilot. In this case he didn't follow
his own advice by going after Captain Wop May entering into hostile
territory. Wop May was on his first combat mission and was desperately
trying to escape from the Red Baron. I might add he did this successfully
when MvR was brought down by ground or air fire. Wop May returned to Canada
after the War contributing much to the development of aviation in Canada.
If you want to read about his exploits do a search with google for "Wop
May".
