Blazing Angels - Help

The game autosaves automatically after you are finishing a mission. After the mission is over you can either redo the previous mission or advancer further. I've replayed the missions for a few times to get the Ace title. Also it's a good idea to make one mission and do the side missions in the SP(upgrading plane and fighting for the Ace title). That way the next campaign mission is a lot easier, as you will enter with a fully upgraded plane.
