OK 3DDave,
I hope you took a minute to think of your own answers before skipping to the answers!
What do we have?
Helicopters / Drones:
[ol 1]
[li]Heli Pilot killed / Drone pilot unharmed[/li]
[li]Passenger killed / Drone passenger killed[/li]
[li]Bystander killed / Bystander killed[/li]
[li]Heli Pilot in danger / Drone pilot unharmed[/li]
[li]Passenger in danger / Drone passenger killed[/li]
[li]Bystander in danger / Bystander in danger[/li]
[li]Heli Pilot in danger / Drone pilot unharmed[/li]
[li]Passenger in danger / Drone passenger killed[/li]
[li]Bystander in danger / Bystander in danger[/li]
[/ol]
So I'm not done the list yet, and here we see that the consequences of accidents, negligence, flaws, and malicious use is just bad all round, for helicopters and for drones to any bystanders and to any possible passengers on board. To the bystanders, it's a question of mass. Drones capable of displacing the functions of helicopters are much more massive than the toy drones, so the consequences of accidents can be drastic as the complexity of drones increases. They just haven't built up to that level yet.
Oh wait, did I not point out that there are NO SAFETY consequences to any drone accidents to the drone operators, standing on the ground far away? Well that's a pretty significant differential in the consequences of an accident. And all the advantages fall toward the operator of the drone. Sounds great.
But what about the rest of my questions:
For helicopters:
[ul]
[li]10. Compliance with helicopter and aircraft design safety code is assured by a rigorous inspection and certification laws, already in place. Failure to comply causes seizure of the aircraft.[/li]
[li]11. Compliance with helicopter and aircraft operational safety code is assured by rigorous training and flight inspection.[/li]
[li]12. Law enforcement can identify the operator in negligent operation through the redundant registration, communication, navigation, and location records of each aircraft in the sky.[/li]
[li]13. Malicious operation of helicopter and aircraft is extremely difficult (but of course it has been successfully done) mostly because of the large number of people and computers involved in most aircraft and helicopter operations.[/li]
[/ul]
For drones:
[ul]
[li]10. A design safety code is absent.[/li]
[li]11. An operational safety code is almost absent. Concealing your identity as the operator is especially easy for BLOS drones (beyond line of sight).[/li]
[li]12. Law enforcement can rarely identify the negligent operators of drones, despite the claims of the drone protection companies. Many examples can be cited.[/li]
[li]13. Malicious operation of drones is quite easy, provided the malicious goal is suitable to the limited mass and payload capability of the drone. Obviously larger drones can do more damage or carry more harmful payloads. Tracking drones engaged in such activities is difficult over cities and almost impossible in remote areas. Finding the drone, or its debris, does not often lead law enforcement to the suspect operator.[/li]
[/ul]
So here we are.
A drone can be operated maliciously, or negligently, with a good chance of no adverse consequences to the operator. Rules that we may put in place to improve the safety of these machines may work on owners who choose to be responsible, but the adverse cost and effort will discourage most.
Meanwhile, there are not many pilots of helicopters or fixed-wing aircraft that don't take seriously their own safety, when it's their own life on the line!
