My Lords, when I represented Carrick, Cumnock and Doon Valley in the other place all those years ago, when the air traffic control in the south had some problems, the air traffic control at Prestwick took over for the whole of the United Kingdom. However, once Swanwick was open, it was integrated and therefore there is now only one NATS service. Would it not be better to have a look at going back to where one could come in when the other failed, and therefore we would have a backup?
