LOL.. Another loser comment. J-20 perform flawlessly and yet to crash like your overprice low quality F-35 and F-22. Made in America low like crap aircraft, scamming all the fools and making them paid over price plane.First mishap in 12 yrs. A jet that your China have yet to demonstrate even %50 capabilities. So by your reasoning, the J-20 are less costly and is a copy of a failed Russian project, that means it is going to be even worse than %50.
I will not surprised you come with comment like J-20 not fully operation, rush product. Plenty of sourgrape cheapshot just to ease your wounded ego.
