Overriding question in my mind is...why? If I want to fly a modern combat aircraft, the last place I go is OFP...the one and *only* strength of OFP is modern infantry combat...everything else is a long stretch. Aside from a really crappy flight model, there are no avionics, no targeting systems, and a horrible control system. Why would anyone really want to put in the time for such a mediocre result?
If I want to fight modern armor, I load up Steel Beasts. Modern aircraft - Jane's F/A-18. Modern infantry combat - OFP. (Vampires and undead - Morrowind III -
@ General Barron!)
Note that I'm speaking solely from the *player's* perspective - I love having armor and aircraft in OFP for use by the AI, or to blow up! But playing OFP from that vantage point is a poor experience, IMO.
