I'm willing to bet that most of the drones that are counted are tiny hobby aircraft (multirotors as well as fixed wing). Most that I've seen bear little to no risk of injury should a crash happen due to light weight and small props.
Compare that to military drones that are relatively huge, made of metal, and sometimes well armed. There is a huge difference.
Is actually the one about the drones. I was shocked that there were over two times the number of amateur, civilian drones flying around than military ones. I will never hack at my neighbor's overgrowing trees again... :)
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
