I was chasing someone in a JU-87G (can't remember if it was on Warbirds or here) for a few minutes.  I had botched a diving attack on him and lost my opportunity to hit him with the big ack cannon the G has, but he was 4k, then 5k out and kept walking away from me while I futilely chased him.  It got to a point where I just saw his dot and there was no distance measurement (he was that far away).  Out of frustration, I loosed an arcing ballistic shot.  For a couple seconds, that shot sailed up above his dot, then down towards it...  then BOOM.  Somehow, I managed to actually hit him.  One shot, one kill with this gun.  
It was absolutely fantastic, and I'm sure he thought I was cheating, but it was just a one in a million shot.
Also, I remember being in a firefight in a German fighter, here I think.  I took two heavy rounds, one that took off my right wingtip, and one that took off my left wingtip.  The nose dropped, stall horn hooted, but as I picked up speed in my dive towards the ground (most of both wings missing), I managed to get control again.  I had coordinated flight again, even though it was performing very differently.  As it happened, I was about 10k feet up and close to my base (furball) so I pointed the plane at the base and started hoping.  To stay flying, I had to have the nose down pretty far, very space shuttle like.  I set up with a runway, killed the engine, and extended the gear.  I flared like crazy as I crossed the numbers at something like 200mph.  I pancaked down on the pavement, breaking off both gear at once, and slid much of the length of the runway before coming to a stop.  .ef and 'You have landed'.  Sweeeeet.
