I'd have to say today it's a lack of information. You can go to virtually any big box store online and buy a drone, and there's virtually no information that comes with that package, or only limited information.
I think the biggest issue is a lack of awareness and carrying the message of where you can and where you shouldn't operate them. I think we all recognize that the drones are going to be here, particularly on the recreational side. That's where the biggest deficiency comes. We're talking to professional drone operators and we allow them to operate in and around the airspace all the time. They're professionals; they have a coordinated process. The SFOC process that Transport Canada established is working very well.
The really big issue today is the lack of awareness on where you can and can't operate them, and what responsibility an individual takes when they hand one of these over either to themselves or to their child. Think of it from the safety perspective of handing your eight-year-old the keys to your car and saying, “Good luck, son. Let me know how you make out.”
