I was wondering, "Where can I find the best freeware, fighter jet, for FS2004?
Basically at avsim.com and flightsim.com
Depends which fighter you're after.
This one is very popular: F-16 Falcon Kirk Olsson
Here's another one: F/A-18E Super Hornet
These links will take you there if you are a member with avsim.
If not, just sign up i'ts free, quick, no tricks and the link will still work once you've registered.
