With respect to Europe, what I think they're doing very well is the studies they're conducting to learn more about the problem. When Frankfurt put the moratorium on nighttime flights, the research showed it was not effective from a health perspective. While it did lessen the number of sleep awakenings, the surveys of people within the community showed that the level of annoyance had not changed since the departure of nighttime flights.
What I think they're doing very well in Australia is information sharing, equal engagement between the community and the airports, and the sharing of information much more freely, to the point where the public can go to the airports and ask for specific information or types of information. There are systems in place that allow the airport to facilitate those requests.
