Roy Brown had to be credited with this kill. The same month the RFC became the RAF - a big headline was needed.
Back in 1967 the first book was written about this. The author cited autopsy notes and if one would read them, it was impossible for Roy Brown to have kill Richthofen. The wound came from below and exited the chest area. By his own admittance, Brown never fired at the Baron from below.
If the red Baron's aircraft wasn't torn apart by souvenir hunters, maybe the truth wold of been more apparent, but I think the Australian unit on the ground pillaged the aircraft because they were pretty sure they killed him
