Mr. Blitzo is continually upping his game gentlemen, Bub, you were always good! (sometimes a little biased toward your J-20?) understandable though! and though you may still have a bias for your hometeam, (you're very honest about that), I find your objectivity and professionalism have grown!
On a personal note, I want to thank you for once again reminding our friends, that Dr. Song's excellent paper, and faithful tutelage to the likes of Yang Wei and others, have created a culture of dynamic innovation at Chengdu! I think I speak for most of the J-20 fans here, when I say that Zhuhai was like a "breath of fresh air".
Oh and Siege, your excellent translation of Dr. Songs paper, along with my old friend the Engineers explanation of J-20 aerodynamics, (I would have loved to have heard him on the J-20 a Zhuhai?? wheres he been???) were the two principle elements of a "light bulb turning on" with regard to the J-20, a planform I had a bias against until I saw the light...
good work gentlemen! and thank you for your hard work.....
