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!
