Unfortunately, this industry is reactive and not proactive like it should be.
It will take a drone to take out an airliner before anything drastic changes. I have a stern hatred for drones because it seems like they have just appeared out of nowhere with no real use but to annoy airline pilots globally.
Actually, the drone industry is getting better. Many modern drones have coding in them that will prevent them flying near airfields and will make them land if they try to approach an airfield.
Of course, you get idiots in any area: people racing Porches along public roads; irresponsible gun-owners; people who wantonly pollute. Most drone owners are responsible.
Among other things, drones can be used to get beautiful aerial photography and video. It should be possible for all to co-exist.
FWIW, I have a drone which I fly out in a quiet part of the country. Even so, on one occasion I was surprised by a Eurocopter flying low (probably 200') and fast where I was flying.
