...probably because I don't really know what it is! that's why I said I wanted to "learn more about" them. I have no idea what the most successful German two-seater was. all I know thus far is that their two-seaters looked a LOT better than most of their Allied counterparts (looks count for something, don't they
the Aviatik? it seems like they were certainly in it for the long haul. I picked the ones that, honestly, I actually have some vauge comprehension of.
I was going to include the LVG on my list, but somehow the others stuck out in my mind more. the DFW seems like it ought to be worth mentioning too...
honestly, I wouldn't settle for just four types of aircraft form each service, because everybody made so many different airplanes just trying to outdo each other.
so, um, is one of those two planes the one you were thinking of? actually, ALL of the German two-seaters I've read about seemed to be fairly respectable planes when they were first sent to active duty. (that just shows you how little research I've done thus far)
that's a bummer that there is so little in the way of combat reports--well, first-hand that is. it seems like the long, arduous path around that would be to start looking over combat reports of people who shot such planes down.
