On the ball member of staff doing job properly with a positive result, thats all you need to know.....
You're asking us to trust them? Without public scrutiny of the resasons for a full blown terminal evacuation, I have little confidence. My first impression is someone seems to have been asleep on the job or initilal procedueres were inadequate, leading to a major escalation later.
It's either a real secret, therefore counterterrorism so I am now concerned, or it's some secret squirrel nonsense. Was anyone detained or arrested?
Why was a full terminal evacuation required at a major UK airport please? I don't want secret procedures made public, just an informed top level view please. We're not quite in a Police state just yet. How arrogant just to say "Trust us"! Dear me.
