There are a LOT of skins for aircraft and tanks that I really like, it is hard to pin a "favorite" skin.
I think I more look for a particular unit than a particular skin, namely the RAAF 75 Squadron and their P40E's with the white tail. Perhaps it has something to do with them being my grandfather's B24 unit escort up and down the slot.
I'd really really really like to find one of the B24 skins my grandfather actually flew in for his missions ("Pansy" and "Shady Lady" were for bombing and "My Ever Lovin' Dove" was for chauffeuring Lt. Gen Harmon around the islands). I dont have enough photos of his plane to get a full skin made, plus his plane was the B24D and not the J we have in AH.
