Im going with the Junkers Ju 87 also knows as the Stuka dive bomber. It had precise accurate bombing and it would dive down and aim the bombs in the dive then pull up and the bombs would hit the target dead-on.  

I may post the unknown but remarkable Macchi MC.205V "Veltro" (Italian for Greyhund)

This small and light fighter performed pretty well aginst Spitfires or Hurricanes ... only problem was that very few were built to have any significant effect on the war, and light armament ...

Oh yeah , ha i forgot about that. Did you know that it was achually the hurracanes that shot most of the german planes down and the spitfire took most of the fame.

Let me guess italien air force

Nice plane though.

And why not the "Centauro" ..... ?

I'm going with the DC-3 she's beautiful

Another WWII "deadly duo" .....

And the plane that forced Japan to surrender
