According to my information, crew involved have failed to meet the 'zero tolerance level' imposed by the Scandanavians.
Sympathies to all concerned, but rules is rules, like it or not
Anyone that has been in aviation long enough will sympathise, the rules are changing, but we have all broken these in the past. It did not mean that any passenger was ever subjected to any safety risk, but there you go.
Another reason why flying isn't the necessarily the best job in the world any more!
Sad, but true.
