I think you guys did great job with changing the North-East airfield into a less PvP zone, but I think the airfield is littlebit too empty.
I think you should add crashed cars, abandoned tanks with dead soldiers sticking out of them and trucks which are either just abandoned in the middle of the road or just being somewhere, to the airfields and especially to the changed NEAF.
This would add a creepy effect to the game, which would show that there really was a massive panic and chaos going on before the events of the game and people were trying to get out as fast as they could, but were killed in car crashes or in some horrible ways.
Also 3 plane-truck crashsites should be scatter on the 3 airfields of Chernarus. You could find some good loot from them, like backpacks, attachements or weapon and also few corpses showing, that the trucks' drivers were killed by a zombie and because noone was driving the vechiles, they crashed into planes that were trying to make a takeoff.
