To finish an answer I started.
I was looking through my "Old Mans" squadron records and as I found no definate number but, I counted over 215 photographs of pilots for the 126 planes of the 354th fighter group.
Many got no kills at all.
Many were killed.
American philosophy was different when it came to flying.
You did not have to fly until you die, like the Germans (or any other besieged country).
You did not get labeled LMF.
Honey/vinegar, thing
If you became an "Ace" and above your options improved considerably.
25 then done for 17 pilots (except of course "Catch 22").
Options to teach others or go on war bond tours.
You almost always had the option to stay, but who in their right mind would?
Passing up a chance to go back to the land of cheap beer & expensive women?
Only to be shot at on a daily basis, and taunt the "Grim Reaper".
The world has enough Hero's, and enough souls who have either willingly, or unwillingly joined the ranks of the "Glorious Dead".
