Snoopy is a WW1 flying ace.
This is a WW2 sim. He doesn't belong here.
Most of the planes on your list are quite rare and had little impact on the war.
The couple that are not (JU52, B29) will be added, I'm sure, when HTC gets around to it.
For a sim that is missing important planes (B25, G4M Betty, He111, P39, etc) I'd think those would get attention first.
