Haven't forgotten this thread and I'll try to clean it up. That just takes a little time and
as quite often there are answers to different themes in a single post, it's not always that
easy. Maybe I'll simply insert quotes to make split threads more readable.
About moving parts to the Aerospace section: That's ok, I think, if a type has reached
service status, even in very small numbers. But, with regards to the 6-shi/8-shi two seat
fighters for example, they remained prototypes and, at least to most of us, more "secret",
than many other aircraft, that never left the drawing board, so I think, they are quite well
suited to this section here. "
Prototypes that didn't enter series production may also be
appropriate at the discretion of the moderators" is the sentence, that to my opinion that
applies here.
But the task of keeping threads clearer and so better readable can be eased, of course, by
starting (new) threads with appropriate titles.
