|Given the low points to which this thread has sunk, I wasn't keen to get back on - but anyway I'll say this: the climber is back climbing, I don't know the full details of his injuries since I haven't been able to speak to him yet.
I have spoke to the belayer, however. He knows he made a mistake, he knows how to avoid it in future, and he is very upset about it and very concerned for the climber. I think anyone can imagine how he must feel. I'm not keen to go into this in more detail in public, I don't think that would be fair on the belayer. If people would like more details, they can make more enquiries and ask the climbers involved. Without being specific about this case, the lesson to be learnt is that climbing can be dangerous unless people belay with good technique, are vigilant and concentrate. Those latter points are particularly relevant in the gym where I think people may have a greater sense of security. There may also be more distractions than at the crag. As well as the climbers involved, everyone connected with the gym, the owners, staff, even other climbers who witness it, are affected by incidents like this - please be careful and don't take anything for granted.
