Like their plans for a new super sensitive detector that could pick up a single molecule of explosive in the entire building - not quite though through. Happens here all the time, airport gets shutdown for an hour every time a cleaner leaves a door open. We have a perimeter fence 20miles long surrounded by trees but they search the airport if somebody leaves a door unlocked.
