The Drug testing industry would never relinquish its hold on the publics' fear.
The Unions would never relinquish their stranglehold on your paychecks.
The airframer would never relinquish its claim to the scapegoat (see above).
The airline would never pay the high cost of "no pilot". Pilots work cheaper.
Until the word "pilotless" changes its definition, there is no such condition. Even AI flight is piloted.
What you think you are sayng is not accurate, what you are discussing is "uncommanded" flight. And that cannot happen, ever, it is physically impossible.
Only the innumerates and not too bright bean counters consider it.
