Not too long ago trains had at least two people up front, three if there was much shunting to be done, now 3000 tons of heavy metal travel from Brissy to MEL with only one occupant in the cab, 'technology' made it possible.
I wonder if we will see RPT flights with only one pilot and technology to take over and divert and land if/when the fertiliser hits the prop?
I bet a dollar that we do - sometime...
