This place has some freeware upgrades(SP3) and many files, skins ect. and plus a forum. And it is still after five years the best and most accurate F-16 simulator in existence. Also there are links to a few other sites for the Falcon4 there including "Freefaclon 2", an upgrade which is also freeware as well.
And also there is supposedly a new falcon due out from G2 Interactive called "Falcon Gold OIR" but will not be free though as I understand.
Long live the Falcon...........
