AFAIK Lock On 1.2 would be the second ever sim, which has (will have) human controlled planes AND chopper(s) (I'm an optimist:)) However nowadays no one can survive without multiplayer capability (hint: dedicated server).
IMHO the first feature gives something unique to the product. I don't know about any sims on the market, or even in development which features both flyable a/c and helos. A good, and only a good dedicated server ensures, that the sim would be played for years after the release.
With other words we definitely need a helo and a major upgrade, namely a good dedicated server.
