You always demand a report from PLA about their most recent jet as proof. It will never happen because that is the way they operate. But we have millions of citizens with cameras even in the most remote region. Were there an accident surely it would be recorded. The fact that they were mass-produced shows they have confidence in their design and reliability. We would think they are intelligent people and know what they are doing. Designing an inferior fighter to combat a potential foe is stupid. Ever heard the adage no news is good news?Again ... calm down!
Only since we have any reports about issues, does not mean there aren't any and the same for crashes.
Even more, I'm pretty sure even with all "over-budget" and "sorftware" issues the F-35 is still the most capable 5th generation fighter around alone based on its sensors and sensor-fusion capabilities, which we assume too for the J-20 but again nothing proven.
The point is again; You take any negative reporting in an exaggerated form for the FF-35 to portray it as a total disaster, which surely isn't correct in the same way you portray anything positive for the J-20 and the absence of anything negative for proof it might be the current epitome of aerial warfare, which again is naive and dangerous.
The accidents with F35 are widely reported and the snafu with F35 is reported by no other government agency GAO I can pull ream and ream of report. It is not speculation or exaggeration It is a fact
