KLF50 at CWL

Yesterday (21st) I saw a KL F50 approaching RWY30 at CWL. I thought this was strange as I thought KL no longer operate the F50 into CWL, and there were no flights due in until 6o’clock (I saw it at around 4 btw). Also it was coming from the opposite direction to AMS. After it approached it went back up and turned and aprrocached again. Do any of you know what it was doing at CWL? :confused: My guess would be some training or something like that. Any info would be much appreciated 😀
