“When it all happens so quickly, you just try not panic andhope there’s some luck with you" Mark Roberts told the British Mountaineering Council's website.
"There was no feeling of panic, more a concerted effort to protect my head and neck and be aware of what was below me, where I was heading and what I could do to slow and stop myself before I got to the more serious rocky outcrops".
"I was a little dazed but, critically, not unconscious. Interestingly, I had the foresight to check the cam was still attached and just hoped the vid had recorded that: it wasn’t one for repeating!"
