Thanks for the responses! (man, that was quick!)
Yes, I had considered the AI option, but what I really had in mind (and i admittedly don't know if it's even remotely possible) would be using just the necessary parts of an "aircraft" (model?, textures?.

) so that it could be used with a program like Runway 12 as a static addon scenery object. Are the files even similar?
I'd like to see a bunch of unusual aircraft parked around the ramp, like the static display area at an airshow. (maybe drive around and check them out in that VW I downloaded!). I realize typical add on aircraft are much more complex 3D objects than most scenery objects and would therefore affect frame rate, etc., but since I'm only "taxiing" I think it would be acceptable.
btw.. as a new member, I think you guys have a great site here, I'm looking foreward to getting to know everyone as time goes by... thanks for the help!
