I recall MadsLad telling the tales from his dinghy recue when training, about 2000. It was still, then at least, a mandatory 'tick box' and caused some problems.
What happened was while he was at Valley they were all taken out from Holyhead and thrown off the back of a Navy launch to be recued by the Valley SAR helicopter. Which, instead of pulling them out of the sea, went off into the distance to answer a real rescue shout, leaving them to be picked up by the launch. Sometime later, while on a later course at Lossie, they has another go. This time they had to drive down to St. Mawgan to be thrown into the sea at Newquay. And guess what happened to the helicopter again - yes, off it went into the distance. He finally got the tick by being pulled from the sea off Yarmouth, third time lucky.
