No. But then nor can we so easily find any of the problems that the Russian and Chinese programs had. Theirs is not quite 'free society' we have.
Did they have problems? Be strange if they had not.
And while you continue to bash on like a broken record, take a leaf from your own book/advice and... learn from history.
China and Russia are amongst the two most blood-soaked secretive and repressive societies going.
Is the F-35/ 5th Gen program doing better than either Russian or Chinese? We may never know, but it’s what we have. Your unending bile and negativity could be considered as 'constructive criticism’, but sadly just comes across and some ‘Pier Spreyish' very sour grapes.
