... or that just means you are in Pakistan.
Even if everybody only used them with the best intentions, someday someone's gonna get seriously hurt by getting clobbered on the head by one of these things.
Still, for now: awesome video!
Yes, someone will get hurt. Someone may even die. It will be terrible, but it will be an accident. We can't prevent all accidents, nor should we try.
Other ways to do it could be by wireless internet.
I would be more concerned with battery life or dangers of mechanical failure on something large enough to use liquid fuel.

If your going to be flying something though the air that has a large range and can seriously hurt someone or damage property, it's not to much to ask that it be registered somewhere. Simple registration number so we know who the owner is.
Edit: The remote can also lose contact and the owner wouldn't know where the plane crashed to cover property damages.
Makes perfect sense, right?
"What if a baseball hits a car or a building?
I mean, those things aren't even under the operators control after they've left the hand (or bat). And my god, think about it! They could fill one with high explosives!
Quick, we need to regulate this. Every baseball needs a registration number so we can identify it's owner, and every baseball bat and throwing arm needs to be licensed!"
When a model airplane smashes into a car, person, building, etc. the owner could be thousands of feet (or miles as we see in this video) away. It's extremely difficult to trace the plane back to the owner.
