Just watched a real interesting documentary from The Discovery Channel called Death of The Red Baron…Pretty detailed and from the standpoinit of their research proves pretty conclusively that Roy Brown had no chance, not even with a lucky shot, to have downed Richthofen. The documentary leans more to Cedric Popkin and even more so to Snowy Evans. I think Popkin probably is the one who downed Richthofen for the fact that those at the scene said Richthofen was still alive when he landed and had Brown, Buie, or Evans shot him he probably would have died prior to landing.Also reading a book written in 1925 called The Red Knight of Germany. VERY interesting read about Richthofens life.
