Guys, its already been answered above, For normal flying we will be as always with externals on, simples. Lastnight was just a test of the concept in co-ops to see if there was any bugs, nothing more, nothing less.
For special events we will be limited, because for things like north africa, neither side wants the other to be seeing what there doing on externals, it will ruin the concept of the event, where fog of war is important, but i'll say it again, for normal weekly flying, will be the same as always.
