I have an idea as to why CAC chose 2002 for their second flying prototype (I think we can agree this isn't a static test bed).Remember last year when we first saw 2001 come out? Well there was that controversy as to whether there was one or two J-20s numbered 2001, one equipped with Al-31, one equipped with the silver nozzles. My line of thought is that they're using the Al-31 2001 as the static test frame (why they needed two 2001 aircraft we are all imaginative enough to think up plausible reasons i think), and so they're in the rare situation where the xxx2 number is free, and they haven't flown a second prototype yet.
So you're saying they have used the 2001(with al-31) as a static test airframe and after they have "changed" the engine to the silver nozzles one which made 2001 became finally the "real" prototype??
