Hi Flyguy35, if it is the default 747 then nobody can email it to you as that is illegal. However if you look through your FS2k2 disks you'll find it on there and can just drop it into the aircraft folder

I'm wondering why adding an effect would ruin an aircraft. Have you tried removing the offending lines from the aircraft.cfg? Or did you just paste the 737 aircraft.cfg that came with the effects over the original?
