I received several emails about dangerous baggage being loaded on aircraft, so I doubled the amount of Tier 3 scanners and watched.
I soon discovered that security officers’ productivity was not the cause. Dangerous baggage was correctly routed into the destroyer. However, when their colleagues arrived for a shift change, the scanners were unmanned for a moment. During this time, every single bag was accepted, including dangerous ones. When new officers started operating the scanner, everything was back to normal.
I remember that Tier 3 scanners used to stop the belt until they were manned again, however this is no longer the case. Can we get this feature back?
