I always get annoyed when I lose an AE wingman due to something I did. I know it's just a computer pilot in there, but still, it often happens when they aren't smart enough and I don't allow for that, or I'm careless.
Like today in the Y-29 campaign. I was flying wing, my leader landed, then I wanted to land, but the other planes in my formation 3 and 4 wouldn't stop flying formation. I can't tell them to break formation because I'm wingman, and my controls don't allow. So I have these two planes that won't stop following me. I land, and then over the radio I hear poor 4 and 3 calling out they been hit. I look back, and sure enough there are two plumes of smoke behind. The poor fellows tried flying in slow behind me while I landed and crashed into the turf. Sad ending to a good mission, they got several kills, I got one and helped to damage another. Kinda spoils the whole thing. Makes me want to kick something.
Oh well, those things happen in a game, and probably even real life. At least those two pilot's weren't somebody I know, real mates in real life.
