Reviewer 2 Report

I appreciated your work.

It is the first one I ever read trying to give an objective point of view on user perceptions towards a technological revolution as widespreading of drones can be. I think such paper can be an effective tool also for helping the regulatory work. In my opinion, the latter is really behind, especially considering the possible impact that drone devices can have on safety of everyone. People opinions are important to clarify which regulatory aspects are lacking and how to address them, so because regulations shall be made "democratically" the study portrayed by this paper is of absolute interest.
