[Metatron]

I agree with most of the above, but still in the case of some obscure aircraft, one needs to sometimes be reminded what was actually used operationally and what was mere fantasy.

I only recently found out about the Arado nightfighter, and if I didn't read about it, I would no doubt have found out about it on this forum, and then googled it.

I agree that it's bad starting requests in someone elses thread, but when starting your own, it can become a good source of information:

Someone sees it, adds pictures, someone else sees it, adds a wikipedia article etc.
