I can give an extra hint, someone just released a FS2004 version of it on flightsim.com (I was browsing thrue the archives last night and found it, and a few others I didn't expect).
Speaking of which, Fabo could you repeat the link from the chat for FS scenery you mentioned?
G-man: Hahaha, that's a wild one, just not sure if it actually flies or not.
I heard a big aircraft very close-by just a minute ago but didn't have time to get past the moving-boxes blocking the windows to see what it was but it was big and noisy and then my mom said it was a strange plane she'd never seen before (not a helicopter) and it was very low down. From the sound it must've been a twin since even the Maule that flew over never made anywhere near that kind of big sound. Sigh, I miss so much
