Spending an afternoon hobbying at the national. Gorgeous light throughout the day until some dark clouds rolled in. They produced a number of rainbows and one of the showers drifted over the runway. It produced the most vibrant rainbow I've seen in a long time, right on the runway. Pictured is KL1179 to Linköping, climbing out straight through the rainbow. Delivered to KLM Cityhopper in March 2018.
