Hello,
I would like to know if it's possible to open any file (how-to?) to check a mission which you just ended.

This would be useful for me to check what was flying around. I have quite some hard time scouting targets while flying on realistic (no navigation aid, no labels) instruments.

I would even love to create a sort of "activity" report: where the enemies flown and when. That would be a good way to use it on coming missions to patrol the targets or the routes with high traffic.

I heard about a J-mode, I have no idea what is that. Thanks!
