Reposted from another thread I participated in:
I've flown real aircraft for nearly 40 years (civilian, military and airlines) and, having thus been exposed to the FAA, here is my $.02 on the subject. It's a warning, really.
It is estimated that one million drones will be sold in the USA this year alone. Some of these will be purchased by idiots, by reckless individuals, and by others who have sinister motives (such as those who shoot lasers at airline cockpits, which, by the way, I have personally experienced). With these numbers it is almost inevitable that there will be a serious incident or accident involving a drone and a real aircraft. There have already been many close calls.
This registration process is just baby step 1 for the FAA. When such a serious incident or accident occurs in the future, the wrath of the FAA will descend upon ALL of the registered individuals. The next step is certification and licensing. Certification and licensing means training, examinations, evaluations, and inspections (and, of course, "fees"). More and more regulations will follow. I am not joking. This is already happening to commercial drone operators, and the FAA will come to see us in the same light.
I hope I'm wrong, but we may come to think of the pre-drone era as the good-old-days of model aviation.
IF YOU ARE NOT REQUIRED TO REGISTER, DO NOT REGISTER. REPEAT, DO NOT REGISTER. You are just setting yourself up for mountains of future red tape.
