Protection from Ourselves
As a once very active licensed private pilot, I have watched the whole drone issue with more skepticism than most. I also might add that I fly R/C planes and even quadcopters (sometimes mistakenly referred to as drones) with FPV (First Person View) video systems. I have not, but plan to get into fully autonomous quad and hex copters which probably pushes it into the official "drone" category.
My concern and issue is that there is no monitoring or licensing of "drones". Anyone with the money can go online (even to Google Shopping or Amazon) and purchase what could be classified as a "drone".
I routinely see guys at our local flying field that have no formal training or licensing but have no qualms with taking off and flying to altitudes of 2,000 -3,000 feet or more and 3 miles plus out from the field. All within a few miles of a major International Airport and a population center of now over a million people. Again they do this with NO formal airspace knowledge or training and a disregard for safety (remember some birds brought down Sully's airliner in the Hudson a few years back).
As with any unregulated activity, it is always a few bad apples that cause the rest of us to suffer. Because we don't self regulate those few bad apples, someone else (in this case the FAA) will do so for us.
