Sasless - crud12001 was the one who raised the time to rescue issue - I was just suggesting a possible reason for it.
As I said, I don't know how much night wet winch training the jigsaw crews do - it might be lot, it might not but it could have had a bearing on the time to rescue.
The Nimrod is usually deployed to act as On Scene Commander but since the crash occurred within 500m of the rig who were visual with it, they (the rig)took the responsibility (and quite rightly so). I just mentioned it because it highlights a disconnect between mil and civvie thinking, even though we should all be guided by the IAMSAR manual.
