I live inside two no fly zones and I been calling the towers every time I'm going to fly, at first they didn't know what to ask or what the procedure was....aaaaa .hold on Sir let me talk to my boss, lol after a couple of times as soon as I told them my name, they already know what I am calling about and all they say is have fan and be safe, that's it !!! and I am talking about a major international airport here in south Florida. So I don't understand what the big deal is, just call the the tower and tell them know that you are going to be operating a drone with in 5 miles of the airport and you want them to be aware...that's simple
