I would like to see a Korean War Arena added eventually, but concede that its likely a long way off. However, I don't want it so much for the jets (although they would be fun) as the additional propeller driven aircraft that could be added to the game. We already have some aircraft in AH that flew in Korea as well, so for a relatively minor initial effort (adding a handfull of new planes) we could have a credible Korean War Arena. Also, there are a few new aircraft that could be added that flew in both WW2 and Korea. I'm not a GV guy, so I can't speak to what (if any) current GV's were used in Korea.
Aircraft already modeled that flew in Korea:
B-29
F4U
LA-7
P-51
Seafire
Yak-9
C-47
Unmodeled aircraft that flew in both WW2 and Korea:
A-26
Tu-2
Gloster Meteor
Other Korean War aircraft:
IL-28
A-1 Skyraider
McDonnell F2H
F7F
F9F
Sea Fury
IL-10
La-11
La-9
F-94 Starfire
P-80 Shooting Star
Mig-15
F-82 Twin Mustang
F-86 Sabre
F-84
Helicopters
I've probably missed a few...... Obviously there are still many things to be added to AH for WW2 so I'm not saying that a Koren War Arena should be a priority, but why not someday? Now, the question is, would anyone fly in it? I do remember the Korean War Arena in AW being a ghost town most of the time, but I think that if enough new aircraft were added (i.e. not just the F-86 and Mig-15) that it could be a credible alternative arena.
