When I noticed Google announced drone delivery starting in 2017 and the fact that Walmart has applied for testing licenses it occurred to me that our biggest challenge will not be the FAA but the corporate "Air Grab" that is about to happen and those that will "control" the FAA. My feeling is that soon we will be told we can't fly above 200' because the corporate delivery airspace will be restricted to those who have paid the big bucks to fly in those zones. Soon we will be paying to fly our drones in small little drone parks that are sanctioned and "legal". Once again the little guy will have to standby and watch the money grabbers eat up another public resource. It was fun while it lasted.
