We can't go back. What's going to be out there will be very prolific. I think it's training at the onset, before we even allow the sales of these things. Technology has to be somehow.... If it doesn't work out, eventually it could be limited in some way.
As I was saying also, and as COPA is saying, it's making sure people have the competency and that whoever they are, they are linked to their UAV someplace so that we can do the tracing. It cannot be a free-for-all thing out there in the airspace.
