The advantage of pilotless aircraft for the military is two fold; time on target and pilot safety.
Modern UAS can stand on target for 30 hours or more, but obviously no pilot can do that, hence the advantage of having them piloted from Arizona on 8 hour shifts.
With regards pilot safety, if a UAS gets shot down (a real possiblity) then it is just hardware that can be replaced, highly trained aircrew take years to get through the system.
I dont see any benefits from a commerical aspect simply because, as someone has mentioned above, you will still need a pilot on the ground so there is no real cost saving, and in the case of a hardware malfunction the pilot is there to sort things out, this is a lot harder if the pilot is thousands of miles away.
Just MO'L doing the usual and spouting rubbish for publicity
