(First off, I have with me a binder with my letter from the FAA that explains photography of commercial aircraft is not prohibited by the FAA. This along with my business card mentions a telephone number an 'authority' might wish to call if they have their doubts). Also in the binder, I have three copies of TSA regulation 1544.211 Use of X-ray System. This proved beneficial on my trip that took me from BWI-FLL-RDU-FLL-BWI. What was the most valuable was having 1544.211(e)(4) at a glance in the outside clear insert pocket of the binder. As I removed my film from my carry on, I requested either to the metal detector "assistant" or the x-ray person that I "need" a hand inspection of this. Of course I got the usual, if it's below a certain speed it can go through reply. Without hesitation I held up the binder in a presentation manner and read while pointing to the words.."TSA Regulation one-five-four-four two eleven paragraph e subparagraph four If requested by individuals, their photographic equipment and film packages must be inspected without exposure to an X-ray system". At BWI, I had to read it about 5 times, telling the screener, I have TSA regulation...<blah, blah, blah> which gives me the right to have my film hand inspected and film speed does not matter. He gave me the schpiel that it can be up to speed of 1200..I said, I want it hand inspected, and speed does not matter..it is in the regs right here that I can request a hand search. Sure enough, two supervisors came over and said if it is in the regs we have to hand inspect it. No problems whatsoever after that. At FLL, I requested a hand inspection and got the same deal. This time it was if it is less than speed 800. I held up the reg again in a presentation manner and read it twice. A young clean-cut gentleman came over and laughingly said, "don't have a fit, we're gonna take care of you"..he whispers to me the screener is new. I was led over to the table with the explosive sniffer on it; they checked my film and I was on my way in less than two minutes. At RDU, I gave the same initial I want this hand inspected. A lady said..this is a new machine it can go through. I said TSA Regulation 1544.211 <blah blah blah>..she gave me a blank stare and called a supervisor. A Southwest Airlines security supervisor stepped over, and I showed him the regs and he told the others there, it's in the regs, we have to do it. No problems after that...even chatting with the National Guard troop and the supervisor about commercial aviation photography. That is the basic jist of my experiences and carrying the regulation TSA 1544.211 was invaluable. In fact, I called the TSA hotline and gave the receptionist an update after each airport visit. She also told me, the people there recommend that concerned passengers carry the a copy of the TSA regulations....it worked. Remember, we are now paying a fee for this service. The screeners are expected to know the applicable regulations or be familiar with them similar to that when you fly, the flightcrew needs to know the regulations. The receptionist told me, it will take time of course. I also advised her that there are no signs at the security checkpoints notifying that passengers may remove film for hand inspection as required in 1544.211(e). (of course this is true since none of the screeners knew the regulation). Overall it was a good experience, and even when I presented the regulations and read them, I was always treated with respect and in FLL the lady checking my film told me I traveled with too much stuff..:). Finally, I even did this as I handed over my film in the lead coated x-ray bags...lol. Afterall, it was the principal of the whole thing. Is the new security following the regulations that we are paying for in ticket fees. Yes they are. (Note:This is only applicable for U.S. airports) Walter DCA
