So far I'm loving this campaign of yours, though there is one little thing that bothers me. There's some kind of bug that causes any NPCs that ride in vehicles to have a random pose. For example, one of the pilots of the Pawnhee in mission two was standing straight up through the roof, and in the same mission the gunner of the offroad you drop of nearby was comfortably laying down instead of standing at the gun. I think it also caused some issues outside the addon, when I played the planes showcase my character was laying in the cockpit on his back.

Just wanted to mention this. Otherwise this is a great addon!
