Two events come to mind.
The first is any time I end up in a 2 v 1 and win. Did this just the other day. I in an La-7, against another La-7 and a K4. Took a bit but killed them both, on the deck, stall fighting, etc.
The other, I was in a Dora and stumbled onto a raid of -38s. I was about 5k higher to begin the attack. In the end I think I only killed two of them though it was fun disrupting the entire Lightning raid.
