There are one or two others I should mention, though, before I close. There's a major cost that's going to hit us in the next few years, probably starting in about two years' time, and that has to do with a requirement to implement another whole generation of screening and security systems in airports for the purposes of determining explosive devices of a very sophisticated nature—plastics and this sort of thing.
D'ici sans doute deux ans, les aéroports devront être dotés de nouveaux systèmes de détection d'explosifs très perfectionnés qui permettront notamment de détecter les explosifs plastiques.
