Thanks a lot for this kind reply and YES, we all have our opinions .... but - I hope You don't mistreat this again as arrogance again - let me add one final question, since this is an issue I already had with others and I would like to understand:
Why is it so much difficult to discuss with me as a foreigner ? You better thrust other reports about anything even without a proof but if an image (IMO a clear proof) is presented it is being turned down as "from a foreigner without understanding" ?
Honestly, it is not so much difficult to differ between an AL-31 and WS-10; no-one needs to be an engineer or aircraft designer and even more why always this "it is so" even without any proof?? And why even more is everything against this not proven taken as an attack to Chinese ideals, capabilities ???
Again I don't exclude the possibility that J-10Cs are flying with WS-10 - I would be glad - and that new units are established ... but as long as all C-models spotted at CAC are powered by AL-31 it is a possibility at best, a rumour, but surely nothing confirmed or a fact.
Maybe I'm too much a nature-scientist, who only accepts something a fact after being proven ... and everything "below" is a report, rumour or guesswork, that depending the reliability of its source has still to be treated with a grain of salt until it is proven.
Or am I wrong?
