[JAMF]

-Extract the .SFS-file that's got the aircraft
-Go into the directory \3DO\Plane\
-Find the directory "P-80(Multi1)\summer" and "P-80(USA)\summer"
-Unlock the .tga-files with the IMGviewer
-Rename the .tgb-file to _b.tga so you can unlock it too
-Edit them and rename the _b.tga back to .tgb

Or put his in your MODS folder and edit them (still need to rename the .tgb again) :
