About This File
This replaces the stock airfield for both FE1 and FE2. The planes are spaced 25 meters apart instead of 15 and arranged in two rows, 10 meters apart. For smaller planes, like the Morane Saulniers, they will seem pretty far apart, but the larger planes, like the Farman F.40 and the Caudron G.4, can now take off without colliding.
In your Terrain folder, make a backup of your WW1_Airfield1.INI and replace it with mine. It will change all the airfields to the new configuration. All the parked planes and all the other spacing is the same as the stock airfield.
