Civil Aviation Bill

I thank the hon. Gentleman for that intervention because I absolutely agree with him. That is why I am very concerned that if cost is a driving force within security, airports may look to see how they can reduce costs rather than, as the hon. Gentleman says, continuing to be innovative. As he so rightly says, it is not enough to shut the stable door after the horse has bolted and say, ““They got through there but we can stop them next time.”” We have to stop them the first time—an incredibly difficult task.
