Assuming the above account is correct, then congrats to the relevant agencies for chasing this one down. Obviously a very frustrating and expensive exercise for all involved, however, if some airline station manager simply wants to avoid a late departure by circumventing security requirements, then be prepared for the consequences.
And apart from the on time issue, if I was the station manager and had a last to board/hard to find pax who then returned a positive explosive result, I wouldn't want that aircraft leaving until their bags were screened anyway!
Haven't seen the paper yet but I wonder if KAL made the deadline for the aviation jobs section this week...
