Not sure if this is the right forum to post this in, but I'll give it a shot. I left the game for about a week and forgot to schedule maintenance on my new aircraft aircraft. It was grounded by the time I got back. I preformed all the required checks that I missed and came back to find my aircraft still grounded. I put it in extra maintenance because I don't know what else to do. I must be missing something. How do I "unground" my aircraft?
