I once killed 999000's entire formation of B-17's with rockets fired from a P-38L. I don't think I've ever killed more than one of his planes at a time since, and I don't think my k/d ratio against him is even positive. But that one time was incredible. I think he laughed more and harder than I did.
I think I rolled in to a dead on pass, and at 1.5K I popped the nose up just enough to lose sight of him, and rippled off all ten rockets. I rolled out and dove away, looking back in time to see all three planes explode into a single fireball.
