You know me. I like to chuck a lit butt into the rattler pile now and again.
I was looking at the Boeing P-26's combat history. It had, in Chinese service, a number of kills against Imperial Japanese aircraft.
Arguably, Imperial Japanese operations in China were part of WWII, although not as generally defined.
You could also call the Spanish Civil War as, at the least, a nice precursor for all the delicious ultra-violence to follow.
One of the beautiful things about the inclusion of aircraft like P-26 or HE-112 into AH would be what I call the "beached turd" factor; the same one that keeps me flakking for inclusion of the Fairey Battle, the Blackburn Skua (which would sort of be uber in an SCW arena) and other similar early war junk. What would be the eny on such scrap tin?
In any case, I'm all for additional eras and aircraft, even from these sideshow theatres. Of course, in the MA (the only place we still have players) their use would be nearly nonexistent. But, if we had more playas...
