Just a question/scenario
Ok so there's a flight plan.
Ok so some bad actor puts a civilian transponder on a bomber with all the correct data in it
Ok the target flies the flight plan route.
Ok so the yanks see these 'civilian' plane on primary and secondary radar squawking the correct code, on the flight path
So how do they 'know' what the target is without sending up something to visually ID it??
Just asking for a friend...
