No state controls airspace, but through both civil AND criminal statutes, they DO impose control over actions and inactions. And that is how they can indirectly control airspace. Another case in point where California and other states may have statutes similar to those in Pennsylvania: "Title 18, Section 2705, Recklessly endangering another person. A person commits a misdemeanor of the second degree if he recklessly engages in conduct which places or may place another person in danger of death or serious bodily injury." Not an FAA regulation. But if you're flying your quad around where an electric company or phone company lineman is up near the top of a pole doing work and you're getying in too close for his comfort, refuse to stop upon his request, and he fears that he might fall or come in contact with high voltage lines, I think I can convince a judge that I met the burden of proof for my case. Even if you were out in an open field away from homes, schools, airports, parks, or other restricted airspace. I could also add the previously mentioned Disorderly conduct charge, along with a few others that apply. What you are doing as a defense attorney is looking at a case through "horseblinders" statutorily. You only look at what is specifically inacted to address a violation. As a prosecutor just like ADA's, police are trained to any and every applicable statute available to them for a particular offense. Did I forget to mention Section 3302, Causing or risking a catastrophe? Remember that lineman? What if when he falls, he shorts out those electric power lines which among other t hings, supply a nearby hospital, and homes of bed ridden residents on ventilation machines? I'm quite certain that California has a similar statute to address that. And if by chance there was a redent power outage, that would just underscore my point in front of the judge. Thete is way yoo much available open spsce to fly quads in this country, to risk fines and imprisonment just to try to prove that you can do whatever you want, and nobody is going to stop you. To that I reply with something my Dad told me years ago: "The Army can't make you do what you don't want to. But it can sure make you wish that you had....".
