Sorry for entering in a rather old topic, but if you look, you'll notice a TON of aircraft that never made it past the Prototype stage in the game or only had a very small amount built. These include the PZL MD-12, the Bushmaster 2000 (only 2 built), Tupolev Tu-70, Tu-110, The original IL-18 (the one introduced in the early 1950s, not the later, very different aircraft, thought that was introduced in 47'), the now cancelled Tu-334 (2 built), AIDC XC-2 and the DC-1 (only 1 built). And that is a handful of what I know right off the top of my head!
But I don't have a problem with that, it does expand the amount of aircraft we can get, and show somewhat of an alternate reality of how it would be if these aircraft did make it past those low build schemes. Afterall, there are also a lot of conversion aircraft (like the various DC-3 T-props and the Valsan 727s, none of which I believe were built new.) As long as the aircraft isn't filled with "paper airplanes" (aircraft that never had reached the prototype stage), I suppose there isn't a problem!
