Small UAVs do not pose any significant risk to people or the National Airspace System. "Dangerous" and "invasion of privacy" concerns are ridiculous, driven by paranoia borne of ignorance. We don't need fact-challenged posts like this to add to the public hysteria. There is absolutely no factual evidence to support the fear of personal drones. There have been more than a million of hours of flight time using these small aircraft worldwide, yet there is not one verifiable report of a drone crash in the US that resulted in a serious injury as defined by the FAA in CFR 49-830.2 to someone not connected to the flight. **Not one**. (A Band-Aid is not a serious injury). It is a safety record that all other segments of aviation would be jealous to have. (In the General Aviation fleet 100,000 hours would include at least one fatality.) Where's the blood and mayhem to justify the perception that small personal drones are a threat to public safety?
Bald, stupid assertions, such as yours, that are easily disproven by documented events, do not help the cause of responsible UAV pilots. Quite aside from the issue of whether UAVs can cause peronsal injury (they have), the argument that they are not a significant risk to the NAS, based on the lack of collisions with manned aircraft to date, is untenable. Consumer UAVs are still relatively new, and the adoption rate is increasing non-linearly. If you seriously believe that extrapolating from the first few years of limited data is reasonable then you are completely clueless. All it will take is one collision with a manned aircraft, possibly independent of outcome, and the FAA (and other equivalent agencies elsewhere) will have all it needs to get authorization to regulate hobby flights so tightly that you can probably write off an entire industry. I suggest you stop blathering and start paying attention.
