And quoted from Breadbox, a 'new member' of the SDF:
"I read the article, they are 100% going off Minnie Chan, no questions asked, J20B+Vector Thrust. If you are following this thread, there isn’t anything there we don’t already know.
I can tell you for a fact that Sinodefence.com is more informed on J20 than anything else in the world."
Posters at PDF (esp. those who not frequent there) may have to grasp the deep imprinted psyche of the so-called professional forum of SDF while there are overwhelming their members who are also members here, both the known and clearly identifiable (use the same userIDs) and those who are surreptitious, be underground here (you never see their traces here but they clearly visit here regularly and even quoted info posted here at there). The materials of essences posted here are right immediately ported there within a fraction of time, mostly with the due credits but some merely ignored such courtesy, while the reverse actions are unfortunately less seen here, thus it's professional there yet here's a fan club, in their words.
It seems some "China Watchers" expect China to open its belly widely to the world through the direct words which are unmistakably understood, done from the position of catching up thus they forget to draw the wisdom of indirect interpretation from the various circulated information. Well, just live with that situation and ignore as necessary all the noises!
