One wonders when commercial flights will be conducted remotely in the same way as Unmanned Aerial Vehicles?
Not for a very very long time. As of the present, they can't even guarantee a 100% datalink connection for CPDLC/ADS comms throughout the entirety of a flight on any single airplane, let alone controlling 30 thousand plus airplanes at any one time from start-up through to landing - something which would require multiple levels of redundancy of secure dedicated discreet datalinks for each individual airplane. It's not gonna happen for a long time yet..
