Well reality is somewhere between your scenario and being hit by a
one kilo blanket dropped from 100m altitude. It would surely hurt,
so much is sure. <br>
<br>
In any case I don't quite see the case for alarm on that specific
front given that at least on auto pilot the devices seem to be quite
fail safe and there is tons of other stuff that has similar risks
that we ignore.<br>

What is working for us, is that it is completely possible
to build a working system that weighs less than 1kg (the
swinglet is < 0.5kg), and fly at ~100m, reducing
potential damage and conflicts to a minimum. </blockquote>

well, a 1kg drone falling freely from 100m altitude would have
981J (speed 44.3m/s or ~160km/h) at impact (OK, simplified
calculation without air resistance), if it were a human being
hit this could already cause serious injury or maybe even
death?<br>
Another reason for wearing an aluminium hat in the future ;-)<br>
