This page shows the UAV used in Haiti. The wings are 1 meter large, this for a weight less then a kilo. See the video and judge by yourself.

In JOSM WMS-TMS Preferences, in the Imagery providers list, look for HT Imagerie de drone, Haiti (ie UAV imagery fo Haiti).  Look for Limonade, Haiti. You will see very impressive results.

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. 

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.

          calculation without air resistance), if it were a human being
          hit this could already cause serious injury or maybe even
