There is a big threat to the lower end of the aviation industry (crop dusters, news choppers etc) from drones. The threat is not physical but of them being replaced by drones. It is similar to the threat of Uber to the Taxi industry. Expect much more fear-mongering about drones, and lobbying from the existing aviation industry. This is why much drone research takes place outside the ol' US of A.
