Heck, I belly landed 6 yesterday. A B26 that I only pinged and ship auto-ack killed for which I got credit, and a 109 that I'm not sure I even pinged, but he got too low chasing me. The others I at least shot up pretty good. The P38 took out my right gear, so I ended up belly-flopping on the runway with nothing but good intentions in the gas tank.
I'd like to see any wheels down landing in the airfield perimeter score as a "landing", while any wheels up/canopy down/crash on deck landing, on the runway or otherwise, score as a ditch. So I stopped skidding on concrete; I still ditched that poor shot-up FM2.
On a scale of importance, I rate that right behind having sheep stickers automatically show up on your aircraft to show how many kills since your last death...
