347 lives lost per year, or one per million people. Similar to Prion disease fatalities. Sure, that's 3 times more than lightening strikes... but that's still extremely low AND safer than whatever. As for the risk of a plane over a populated area, I think it's safe to say that a 4kg drone is a much lesser threat than a Cessna weighing 200 times more, and that's a very small plane. So it's really not fair to compare a drone crash and a plane crash (we're not talking military drones here, I hope you've read the article). "...I can only see delivery drones being safe with a built-in fixed wing that allows it to glide to the ground power-off below 10 mph": and it seems many people disagree but feel free to prove them wrong and show the world how you can glide a drone to the ground in a dense city to deliver blood at a hospital.
