Surely the issue is when control from the ground is interrupted and the aircraft becomes (presumably) autonomous?
So the training and airmanship needs greater focus on this aspect - (the lost link 'autonomy' is Called Return Home for Israeli systems, and Emergency Mission for General Atomics products) ..This aspect is a 'fundamental' issue of RPA management - as equally important as MSA adherence for IFR
flown by rated pilots (such as Predator, Reaper, Global Hawk) and I see less infringements from these types than manned types because of the SA they have in their Ground Control Stations.
I think you are basically correct here, but it is not the SA of the GCS, more the ABILITY to communicate if 'classical' comms are lost...ie the telephone is a good back-up.
There are a good number that never make it to the public eye
...but comparing
ALL UAV / UAS / RPA / Drones is like stating that a 747 and a Cessna 150 are all flown by like minded professionals....
