All this business about Dutch arrogance or attitude is complete and utter drivel. The same would be said about BA, Lufty or almost any other major airline.
As Piltdown Man said earlier one day we will find out what happened for these guys to believe they were on a runway. This will be a fascinating read.
What is so intriguing about this incident is that these guys had been flying for a number of years, like most of us. They had been regularly and successfully going through sim checks and line checks, and yet, they were able to make such a basic mistake. KLM does not employ idiots, whatever some may appear to think. And yet it did happen to them.
As far as I am concerned what is to be learned from this is that, potentially, anyone is capable of a major cock-up, especially if you think it could never happen to you.
