one of the problems with a pilotless airliner is this>
it will do fine with all the information entered in to it, even while enroute.
but
the one thing is the unknown. for example the Brazil mid air. with or without pilots on the 737, the last backup for radar/tcas and the like was the MK I eyeball.
sadly, it failed too.
I hope there is a pilotless airliner soon. it will probably be used by FEDEX or UPS first...their pilots get paid way too much anyway!
but please, keep the thing away from my neighborhood.

ps. there will be more flights grounded by the minor stuff some pilots choose to carry .
