The highlight of my Wx3 time was the night we were tasked to assist a frigate (at Portland) that was doing a night IFR (in flight refuelling) task during a CASEX (simulating a submarine attack). The brief was to hook up then simulate fuelling. All was well until the skipper of the frigate announced that now he was free to manoeuvre he would be taking avoiding action on a suspect submarine contact. He then proceeded to 'tow' us around at high speed into wind, cross wind, down wind, and all on a dark night. It was almost comical but when we finished I can reassure you that I was completely knackered!! Never again! If you ever hitch your helicopter to anything that moves be sure you know where you are going.
