In reply to D Douglas: Stockport/Liverpool:
Faulty equipment or faulty tying in?
Reference to the harness seems to indicate that it's something the climbing pair should have spotted (worn equipment or incorrectly tied knot) rather than an issue with the wall equipment.
These are the questions that are important and the whole climbing community should examine them closely to help future accident prevention.
I'm also involved in SCUBA diving and I have to say that my experience of climbers is very much a 'bury your head' in the sand mentality. I don't really understand the mentality that if you don't discuss these thinge they won't happen again. In SCUBA we tear every accident to pieces and learn everything we can from it in order to help stop it happenning again.
We don't try to sweep these sort of things under the carpet, that's a very unhealthy attitude. Look up the work of Shek Exley for examples.
