Re: Why Just War Zones?
(Seriously, it might be simpler to require drone pilots to submit a flight plan for every flight. Like real pilots do.)
Not all real pilots. Class G is fairly loose, and that's where - by and large - drones should/will be operating. It's a rare thing for a glider pilot (for instance) to submit a plan unless they're intending to ride wave up to FL195 or otherwise play in lower Class C space.
