Not really amusing. A GoPro Karma w/ battery & camera weighs a little over 4 lbs (1870g) and, depending on the height from which it dropped, could do some serious injury. And there are MUCH heavier drones out there.
There appears to be little regulatory interest in requiring manufacturers to incorporate some means of retarding the speed of a dropping drone - such as a drogue chute, auto-rotate or similar design. Beyond safety to those on the ground, you’d think it would also be desirable for saving the drone itself.
Not that drones are alone in this regard. Same goes for the RC aircraft hobby. One unexpectedly dropped in a straight dive 15ft from a group of us & was heavy enough to have killed someone.
