I refer to your editorial, “Clear guidelines needed to regulate drones”.
While I agree that some regulation over the responsible use of drones is desirable, I caution against overreaction, and over-regulation.
Yes, drones flown “for recreational purposes only” are considered model aircraft by the Civil Aviation Department and do not need approval. But, just as at ground level, Hong Kong’s airspace is crowded, and as drones become cheaper, easier to use, and more accessible, more of them will be heading for the skies. So some form of regulation or control is probably needed.
