Forgive me if this is a question for which there is an answer in the forums already but I tried a search and did not find the answer either that or perhaps I'm missing something obvious. I can't seem to find a way to save a mission in progress. I'd like to be able to save a mission, for example, when I'm already setup for a special maneuver or some such other scenario. I'm sure it's easy but I'd appreciate the help. Thanks.
