I have no idea how they lost the plane. there are tons of transponders all around, I suppose they could be turned off but there still would be a black box and other equipment. That's the main part of the story that confuses me.
Same goes for invisible plane and no one hearing it.
The pilot would have made emergency calls before he ejected and they 100% plan alternate airfields to land in for an emergency.
I have heard a rumor that the plane auto ejected him like your hack theory. So maybe it's the first fighter jet hack.
Or maybe it's all part of the show.
that is a big jump to assume the plane got hacked by a hostile entity. possible but would be the first time of that sort of attack vector.
radios would still work though you can't hack HF/VHF/UHF
