I hope you’re correct.
I hope so too.
If, it was a botched hijacking then the sponsors would keep it quiet and not tip us off that they can still hijack an airplane. They would want to try again. The airport or whoever ran security would not want the public to know that their security is lacking.
If it was a rogue pilot then the airlines would not want that info made public. Lots of cash to lose there too.
If it was a mechanical problem then the manufacturer would not want that info made public either.
I think that the stolen and hidden jet would be the most likely answer we are given. The jet, hijackers and passengers would never be found.
Dead men tell no tales.
