pictorial evidence is also guess you are seeing what the puppet masters let you see, there are also satellites and pictures where more than 20- 30 aircraft should be seen, if satellites can not see 20- 30 aircraft, then the number is low, no pictures of 5 or 6 J-20 together the number is likely low, how many there are? no one knows, close to 90 is niether a right one nor 28 simple because the puppet masters will let you see what they want
yes there was once a guy who told you China will buy Su-35 you and your friends said no, you were proven wrong in revenge you banned the guy, same was when you were proven wrong when you said Su-57 bort 05 was not going to fly again you banned the guy, some one told you do not speak Chinese, I do at least Japanese and read Chinese/Japanese ideograms you got angry and banned the guy, some one told you facts about J-20 aerodynamics but since you are a plane spotter not an aerodynamics engineer you felt angry too,since you know little about the subject, you banned the guy too, you really really are an honest guy
