Dunno. It is good that the Chinese members here are proud of what China accomplished and I have never said they should not. Heck, I left aviation over ten years ago and have forgotten most of the math I used daily and we used a lot of junk yard cars in the radar range instead of sophisticated software, but if there is a god of aviation, perhaps you as a Greek can check your mythology for one, he must be laughing his butt off at the claims these guys made and still making.
Apollo must be the God of flying, but Greeks assign Ikarus as the protector of aviators, and actually call all cadets 'Ikari' .
That's funny, we used to use old Unimog trucks to test and calibrate our fighter and AA radars, works almost as good as software.
