I've landed so many times at HAU, and it's windy for sure! I remember one flight with SAS on a 737-600. A lot of crosswind and rocking from side to side. I was looking at the horizon out of the window, and then there were just trees (the trees you see on the final before touchdown in this vid) for two seconds before the plane leveled again. Got a little bit shocked by that, to say the least.
