Re: What is the sky?
#6 bird shot only has an effective range of 100m or so fired upwards
100m is over 300ft, which is well into Amazon's proposed "commercial drone" airspace. That's a pretty long way when we're talking back-yard operated drones.
And I imagine it doesn't take a lot of physical damage to bring down a small toy drone - a single pellet strike to any of several components would probably do it.
