Hi Joe:Thanks for the info. As it happens, the first FSX I purchased was the Deluxe version, but I soon discovered that it wouldn't do everything I wanted (or it lacked in someway that I no longer remember), so I purchased the Standard version and the Acceleration version.It makes absolutely no sense that EVERY VERSION of FSX doesn't have exactly the same features (maybe)! Or maybe I should have said, there should be ONLY ONE version of FSX.However, all this does not explain why the FTX, Avalon, and random others, aren't available in FSX, unless MicroSoft has included some bit of code that prevents any aircraft but theirs from being available!Joe ShotwellEldorado, Texas
