So Spanair dispatchers simply picked up heap of paper that came in throught the fax and handed it over to Nordic crew without even checking what's written on it? Error of omission if you ask me.
It would be unthinkable for anyone at Spanair, or anywhere else in Spain to mistake SVQ for SCQ or viceversa.
Or rather it would be unthinkable for anyone at Spanair, or anywhere else in Spain to admit (s)he made a mistake. I'm not saying that mistake was made in Spain but this attitude reeks of someone who never underwent proper CRM trainning. Mistakes happen and what matters is error management! Have you ever heard of a typo? Look down on your keyboard and tell me how far are C and V.
