I'll have to examin this evidence and maybe people like
@siegecrossbow @Blitzo to weigh in. Like I said, the circumstances of the meeting are most important, regarding whether the F-35 revealed itself voluntarily or was detected when trying to remain stealthy. I don't know what you mean by saying "the same pilot of the old flanker make it twice in a week" cus there's no possibility that he tricked 2 F-35 to crash into the ocean in one week without shooting either down which would be a massive incident. Old or not, Flanker was made to dogfight while the F-35 was made to hit-and-run so if the F-35 gave away its stealth, it is absolutely expected that an entire array of 4th gen fighters would beat it like a fat child in a knife fight.
