Two little questions.

Hi everyone!I have two questions for you guys:1. Is there any way to add nature sounds to FS2004? Because I've tried flight simulator x demo and it has nice water sounds, bird sounds and other sounds that give more realism to the simulator. I want to add this sounds to the background so when I shut off the engines I can hear them. Anyone knows a way to do this?2. Is there a FS2004 version of the FSX's glider? To be exact: the Aircreation 582SL?? Because I've searched the web for gliders and ultralights but I can't find any that looks just like that one, with a delta wing...is there a similar plane for FS2004? (pd: with delta wings only, because I've found a lot of non-delta wing gliders)Thanks in advance!!
