I could be wrong but, when the commercial aspect comes into play, such as businesses making drone deliveries to customers and it's in the works, the regulations will get very complicated. I saw a video a fellow made at a car show with his drone, it was done beautifully and I enjoyed watching it, only concern there is, had the drone malfunctioned and dropped down into a crowd of people, possibly injuring someone, the consequences could have been catastrophic to the owner/operator. Liability insurance might be an answer, but who would give liability insurance on drones? Possibly the commercial operators would have this under control, don't know. Being in it's infancy, lots of questions. PJ
