I would agree. I think drones are very useful. They are lower cost than the operation of a fighter aircraft, or another aircraft that might be going to check out what could be triggering a threat but could actually be something less than a threat, for example, perhaps a flock of birds or something is showing up on radar and you need to identify and verify whether it is or isn't a threat. That can be done by drones.
They are cheaper, lighter, easier to upgrade, and they give you great range. Canada has a tremendous coastline and an enormous amount of territory to cover, so for the dollar a fleet of drones could do more than the cost of a single fighter aircraft. In that sense, it could be a very promising technology.
