After Art had put 66 down and they all got out did it not sink? I don't think they had to wait long in the dingy.
It did eventually sink, long after the crew were picked up by the Seaking that was already airborne on a SAR exercise. I believe it floated for several hours before sinking.
When it ditched, I was flying on a SAR top cover for another Helo who was picking up an injured trawler-man.
