European Global Navigation Satellite System

I am grateful to the Minister for giving way. On that very point, may I give her one example of an important benefit? The aviation business increasingly depends on global positioning system technology, but there is no redundancy. We have no alternative method of positioning, using satellites, so if the system goes down—and it can—it will create a grave danger to aviation. Leaving aside the issue of costs, which is obviously important, does she agree that the principle of ensuring redundancy in such an essential navigation system must surely be right?
