Amazingly, despite all the publicity created by this thread, another party was issued with a skyhook at Penwyllt a week or so ago. This should not have happened! Reading their account in the logbook, complete with diagram, it would appear that the 'nightmare scenario' postulated by Andy Sparrow (i.e. that the skyhook would semi-lock or jam so creating the illusion it was safe) did occur. Fortunately, it did not fail (the downward pressure exerted on the ladder must have been sufficient to keep it in place) and no injury resulted although the person first up the pitch (a highly experienced caver) did get a nasty shock when he got to the top.
Hopefully, this will not happen again. A warning in red pen has been written on the board next to the key cupboard and I have been told that the skyhook has now been removed from the cupboard (this should have been done after the last incident). However, it is worth spreading the word to anyone who may not be a regular reader of this board.
Anyone wanting to visit the Upper Oxbow Extensions should be prepared to free-climb the skyhook pitch (with protection) or go the long way around over the high level traverses and then abseil back down the pitch - this latter option is a better trip in any case.
