Wow, Pat, I knew things could get dodgy when you go back in time to mess with the time-space continuum, so thanks for weaving open destinies for the aces.
RE Jasta 11 example: What would happen with the CO post if, say, ol' MvR just happened to have an untimely...accident? If the player had sufficient rank, would they then become CO?
How about squadrons that the player has risen to command/started campaign as CO, but were historically commanded by an ace after a certain date?
