The following episode happened on a flight from Trondheim Airport Værnes to Oslo Airport Gardermoen in March 2015.
The winter in Norway can be quite a winter. You can get -20 degrees centigrade or a meter of snow during a day. Winds can be quite strong, rain can quickly turn to hail. Flying in Norway demands quite a lot from the pilot. Or the personell in charge of keeping the runway free from snow.
