The British Mountaineering Council (BMC) says the climber who filmed himself falling around 100 metres on Snowdon probably survived because he was wearing a helmet.
It also praised the reaction of Mark Roberts' friends after he fell.
Accidents do happen, but Mark was well equipped, wearing a helmet, and that probably saved his life.
The other climbers in the area did exactly the right thing. His friend dialled 999 and asked for the police as soon as they saw the fall, and he was lucky in that two members of the mountain rescue were climbing nearby.
The team got to him within 30 minutes. Of course, we always try to be fast, but this time we were quicker than usual!

"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!"
'Stubbornness and sheer stupidity' to drive up Snowdon
A trial has has begun of a man accused of motoring offences by taking a car up Snowdon, even though he has not appeared in court today. 40-year-old Craig Anthony Williams from Cheltenham denies two charges of dangerous driving following separate incidents in September 2011.
