1 Vote William Barker
Undisputed fact that it happened.
He had basically earned the VC prior to his actual VC action. Many were saying "What does Barker have to DO to get a VC?"
The spectacle that was his action, IE fighting 20+ enemy planes by himself and manageing to get 3 after downing a 2-seater, right over the lines...getting cheered after the fight. If it wasn't witnessed, no one would have believed it, it's just rediculous.
Fighting with serious injuries.(AA Mcleod and his observer come in 2nd on this one for me)
Surviving the action.
Ironically he was completely embarrassed about the whole thing..getting surprised after taking out his 2-seater...target fixated.
