I would LOVE to see a Vietnam themed release of aircraft. The A1 Skyraider is one of my all time faves. Couple that with the Huey and you have some CSAR goodness going on. A Jolly Green would be cool too. And a Skyhawk, and an Intruder, and..... lol
Would definitely need a new "world" to fly in though.
Love the idea and a lot of those a/c could be used for the 60s/70s middle eastern conflicts too.
