British airport

The sound clip appears to have been made in an airport in England. There are noises that may be coming from the outside--jackhammers and bicycle bells or from a more distant part of the building. Perhaps the bells are on some sort of luggage cart? The sounds of people walking briskly, some in high heels and one running, and the voices of children and men talking closer to the recorder all sound as if they are amplified by being in an indoor structure. The resonance of the shoe noises also suggests flooring common to an airport. The announcements on the PA system are in British accents and mention "airport"--possibly the international wing (a man at the beginning seems to say he was just in Brussels).
