But the real question is whether the persons operating the UAVs are getting flight skins or are really pilots. Believe most are not pilots (wear wings, large wristwatches, small etc).
Video game operators for sure, and maybe good technicians. But when it gets all quiet and there are no fans for anything to hit is the person on the ground going to (1) be able to talk to the air vehicle and (2) be quite as "invested" in getting it on the ground in one piece? I think somebody said that the prospect of your imediate demise wonderfully sharpens the senses and attention
