The policy is not specific to duty free. I was caught by it last month during a domestic trip in France. I had bought Armagnac from a local producer in the South of France, and was flying bag to Paris. Luckily, the registration mentioned the policy, and gave me time to stuff the bottle in my checked-in suitcase. The rule is simple: you cannot bring a container greater than 100 cc, about 3 oz, in an airplane through security. You can bring several containers of lower capacity than 100 cc, but the combined capacity of these container is limited; they have to all fit in a 1 liter plastic bag. The theoretical rationale for the rule imagines terrorists mixing products in a bottle. Each of the products is supposedly harmless, or at least not detected by airport security machines, but the combined result is explosive. By limiting the capacity of the container, the security folks hope to limit the potential of any device fabricated aboard the plane. Those of us who have toiled through chemistry labs may find the all idea somewhat theoretical. You may remember the dire warnings of the teachers about what happens if you fail to control a reaction, if you let it overheat, or if you shake it a little too much. You may consider the improbability of repeating the experience in the shaky cramped space of an airliner's toilet. But then, you would not have the same mindset as the airline security folks. Given the rationale, I am still puzzled by the fact that bottles bought after the security check are allowed on board. Probably has to be a compromise between air traffic security and airport economics. -- Christian Huitema _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
