With servicing and weather problems it's quite normal to fall behind normal scheduling and then there will be catch up for the next few days, so it can be quite normal for flights to be leaving at that time of the night to various offshore problems. The metar was fine but I for one disliked going out at night particularly in the winter. 0 degree isotherm low, rough seas, strong winds, heavy rain, reduced vis due to snow. As for summer all the above less 0 degree and snow but factor in fog, the North Sea crews earn their pay. Well done to you all and take care.
