Rather lacking in imagination. It was actually (3) trying to kill an aircraft who was feigning ACM but actually just trying to drag me to flak. My theory was he couldn't find his deploy balls lever. Flaks didn't get me though, I'm far too smart

I see... So it happened once, and you decided to start this thread?
(I mean, it's not like people running to acks or to friends is unusual in these games. In fact, the latter is 10 times more common in my experience. They dive and run towards their friends. If you dive down after them, you're on the deck and find a couple of high icons ahead ... Just like the Wirbles, you don't see them until it is too late.)
