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?
Another reason for wearing an aluminium hat in the future ;-)
