Shortly after launch, I got the one for landing on a grass strip (can’t remember the title offhand) when I was still at flight levels over the Gulf of Aden. At that point, I had never landed on ANY grass strip at that point.
I remember getting a couple of others at odd times when I knew for sure I hadn’t fulfilled the prerequisites for them.
And there are others like flying X nm in each plane in the default edition. I should have that one, but don’t.
