19 Tons is likely pretty low for the J-20, but then you're the expert who was professing 15 Tons, but I guess you're now up to 16.5 Tons now right??? you feel free to believe any number you wish?? but those high G loadings will break most of history's older lighter airframes...."No doubt" LOL Math non-existent, eyeballing logic fail. But let's just add the "if you know anything about..." in there so the feeble-minded will be inclined to agree with you to look like they "know stuff"... by your definition. Just one question: in your imagination, is it that the higher the weight one calls the J-20 the more s/he knows about "structures" or does one just agree with precisely your 19 for maximum "knowingness" and any other number detracts from it? LOLOL Called you out on this "tactic" many times; learn a new trick, will ya?
