While your idea has only good intentions, I have to agree with Staffan and Ivi.
First, we are not (if you will pardon the pun) on the FAA's radar. We must keep reminding ouselves that as far as hobbies go 'plane spotting/photography' do not exist in the eyes of the overall US population (even those in the biz) and even in it's birhtplace the UK, it is a mystifing pastime. Also, keep in mind that there are NO FAA rules against photographing civil airliners in the US from an observation area or any area where you are not interfering with aircraft operations, i.e the ramp...Period! The problem is communication...the police, nat'l guard, ect..have not been educated about us, and why should they ? Again it is the lack of visibality that this hobby has. The #1 reason that cops stop us, is because someone saw us up against a fence with a ladder (I still have a problem with the use of ladders, even before 9/11 I questioned the wisdom of using these) and made a cell phone call. Remember we (the US) are still under the highest state of alert ever, and for the average person seeing you up on a ladder pointing a camera at a plane, well that would definetly send up a few red flags. Frankly, if I were not a spotter/photographer, I would probably call that in as well.. Speaking to several officers, most rather not bother with us, they have bigger fish to fry, but they are required to respond to those calls.
Also keep in mind that places like NYC where aviation photography has been tightly controlled since the late 80s, these rules are not laid down by the FAA, rather by the Port Authority. In many instaces where a cop states "It is against FAA rules" that is pure BS, but if he/she should happen to say that "there is a city ordinace forbidding...." then you had better do your homework on local ordinaces, before venturing out to the airport. Technically, an airport terminal is public property, funded by the taxpayers and as such you can photograph to your heart's content except of course for the screening areas, customs and other sensitive areas, however it gets a whole lot grayer when you are outside of the terminal and on the roadways that circle said airport.
Second, the last thing I want is another gov't buercracy dictating to me if I am allowed to enjoy one of my passions. I lost my ham radio ticket many years ago because I would not obey the FCC's tyranical and outdated rules.
Third, no one in their right mind pay a 'fee' to watch planes!
Actually, the ball is in our court. And with the recent spotter incident in Greece, we are not exactly batting a 1000 right now in the eyes of the public. We can either give the local authorities a hard time and further hurt our cause or we can move on and contact our local represenitive in congress, the city, the airport authority, police, ect...and keep pestering them until they acknowledge your complaint. IMHO, however nothing short of organazing, nationally or internationally and bringing our hobby to the forefront and getting some good press will give us the visability that we sorely need..
On a side note, I would be interested in hearing from any European spotter/photographer who was active in the early 70s when Carlos'the Jackal' attacked an EL AL 707 (missed) with an RPG from the observation areat at ORY. If I remember correctly, as a result, security was heightened to unprecedinted levels. So how did that effect spotting and photography. Perhaps we in the US can learn something from that incident
