I'm watching the drone take off and it got me wondering. If these things went into service, how does the tower and the drone communicate? How would it know which taxiway or when it is cleared for take off? Would it be some remote operator in a trailer talking to the tower? Would it be the guys in the tower pushing the buttons/joystick? Just how autonomous are these things to be? If a squadron of big, thirsty bombers needs refueling, how many drones would there be? How would comm protocol work out?
BTW, I think drone tankers are a great idea. They could orbit the fleet without fatigue. Big help for the CAP.
