Not sure if its classed as scenery in FSX, but if it is, it will be in the scenery folder. As my carriers are stuff ive downloaded, they appear in the addon scenery folder. Dont know if that helps.....!
No, I've looked all over many times through all the scenery and texture folders I can possibly think of, but couldn't find it, so I must have either not looked throuh the right ones or accidentally skipped over it about 3 times in each folder.
And I'm talking about the carriers that come as defualt with the FSX Acceleration extension. But thanks for trying.
