There are always nice Dutch people around and there are always the
amongst them. I am half Dutch and the attitude of some of my relatives get on my nerves all the time. In a suburb in AKL where an aunt lives, the Dutch community wants everything their way ( because of Tasman? ), edam, clogs, mini windmills at the Sunday market but when someone suggested putting a Chinese arch as part of a scheme setting up a small Chinatown ( a big Chinese population there ) there were deafening protests from mostly Kiwis of Dutch extract who opine that that will be the end of the Dutch world! Really xenophobic!
Coming back to this KLM B737 incident, night time departures and tendency to rush could have contributed to it. Fatigue could be a factor but I guess KLM pilot schedules are fairly relaxed compared to those of Easy and Ryan.
