You're wanting a small staff with limited resources to cover the history of flight from Kitty Hawk to Iraq to satisfy some inner need to say "oooh cool"...has nothing to do with consideration for HTC's business model, practices or monetary gain.
You're saying things I have not. I don't care about modern types as it would be contrary to the essence of AH which is essentially high performance aircraft before the introduction of A-A missiles, where it was men maneuvering to get to an advantageous point where they could get a guns kill(basically ) . The Korean Era is in fact,at least for the early part, in the spirit of such fights, encounters, etc. If we went about "oooh cool" then why don't we play using wire frames from 1992.
It takes nothing to ask and consider it for a later time if time is available, just like the 4 WW1 planes we have although the Korean Era Jets would be much more complicated but I'm sure the team can do it, as they have before on other aircraft.
