It's illegal to operate a drone within five miles of an airport. There are about 5,000 airports in the U.S. Make sure you're not near an aiport when you shoot something with a drone. It may be more difficult to avoid an aiport than you think. There are guys flying drones around a public park near my house where I walk my dogs, and it's a half mile from our airport. I've warned them, but they look at me like i'm crazy and just go right on flying them. I really don't want their stupid drones causing a plane to crash into my house. Next guy gets photographed and reported to the FAA.
