Remember the good old SOAR Airlines livery one could find in FS2004?
If you missed it in X-Plane, here it is, altough it has never been a default livery for the 737-400 in FS2004.
I have changed some things to make it a little more "smooth".
Have fun and happy landings!
Only tested with X-Plane11, should work with X-Plane 10 too.
