just 3 questions that im hoping the enlightened ppl of the flightsim community can help with

1.Can i use FSSC(Flight Sim Scenery Creator)with FS2004?

2.Why when i load up downloaded aircraft(ie a Harrier) do i hear a cessna's engine (ive looked at the sound.cfg file and it say's alias=Lear45?)

3.Any news on when AFCAD and TTools add-ons will be available to use on FS2004(i already have TTools but im wondering about the aite program)

thanks for the help and sorry if the answers are obvious
