What I hear is the desperate sound of arse-covering. Most likely there has been a massive overreaction to a couple of hysterical phone calls. Followed by the publicity given to these phone calls giving rise to a whole lot more. Followed by those in authority wondering just what it is they have done. And trying to find reasons that it isn't their fault. No conspiracy, just monumental incompetence.

The alternative is that a couple of spotty teenagers in a garage in Crawley have outwitted the CAA, the police, the army and the security apparatus of the UK. Not impossible, I know.
