This is my response to it:
I have been approached while doing photography at airports. Some who don’t care about me being there, and some who don’t want you there at all, and thinking there is a law about taking pictures of aircraft. Safest thing to do is make sure your in a public area like a PUBLIC street, sidewalk, or if your lucky on your own property like me who lives next to an airport. Keep this in mind IT IS NOT UNLAWFUL TO TAKE PICTURES OF AIRPLANES!!!
