Travelling back to Manchester from Dusseldorf last Friday, passing through security at around 1750, I was staggered by a breach I saw.
The German security staff were being extremely thorough on x-raying hand luggage, one piece at a time, and were strict to ensure that each person passed through the metal detector singularly.
The area was busy, with about a 5 - 10 minute wait. A lady at the back of the queue attracted the attention of a Lufthansa employee to help her through as she was late and the flight was boarding. The employee took herself and the lady straight through the metal detector complete with jacket and handbag. The detector beeped, but the Lufthansa emplyee just waved the person on without regard to the security staff and they disappeared in the direction of passport control.
The colleague travelling with me was as surprised to see this as I was.
