So what is the benefit of pilotless airliners exaclty? In the big scheme of the operation the pilots wages are insignificant anyway.
Next is the question of who is going to put thier money on the line to refine and develop the technology, and thats all before some regulator somewhere has to stick thier neck out to even certify it (We all now how difficult it is to even just get a medical renewed in a timely manner)
Once all thats done you have to convince the public there is something in it for them and get them on board... the same public who form thier unwavering views from social media and WhatsApp groups.
Remind me again what the benefits of a pilotless airliner were that make over coming all of those obstacles worth the risk and expense?
I dont doubt it's technologically possible, I just dont think its feasable in the lifetime of anyone here.
