It'll be "fine"... until one hits a bird (or a non-ADS-B drone piloted by some idiot) or has some sort of failure and it then dumps a 5kg package onto someone's car/house/head/child etc... then we'll get endless hours of "news" reports with headlines like "killer drones" or "death from above" and the inevitable outrage on social media.
On the plus side... it'll give all the Chemtrail/"Govt is spying on me" conspiracy theorists a new target
