Okay.
I will turn to Mr. Johnson now.
Drones represent a sector of economic growth and we welcome that growth. They raise issues of responsibility and safety, as we have heard from several witnesses. You are talking about making our regulations consistent with U.S. regulations. You have contributed a great deal to these regulations.
From what I can see initially, there are three kinds of drones. There are very small ones, which as I like to say are the kind that destroy the inside of a house and that children play with. There are the more commercial ones, used by amateur photographers. Finally, there are drones designed exclusively for business and transporting merchandise.
Do the U.S. regulations reflect these types or do they focus on the weight of the devices only?
