Parents in Wiltshire urged to ensure children know about 999

Gough said the incident in which a teenager “stayed really calm” during an emergency happened earlier this year.

Henry, 15, from Wiltshire, had learned what to do in emergency situations in the scouts, so when his friend, Dom, 12, was injured in a mountain biking fall, he knew how to react.

“I just thought it was a normal crash. I went to check he was ok, but he was unconscious.”

Dom explained they were in woodland in January, looking for new jumps to do when he “was going too fast, lost control, flew over my handlebars and hit my head on the ground, the bike landed on top of me”.

“All I can remember is I was really cold, it felt like I was dreaming.”

Henry went to call 999, but had no signal, so enlisted the help of dog walkers.

They put Dom into the recovery position, gave him extra layers and were able to call.

Henry was able to give them their exact position through what3words.

“It was a bit scary but I knew what to do, I learned it at scouts.

“On expeditions or anything really, there could be an accident anytime and I had what3words in my phone for that.”

The helicopter landed four minutes after the call, just two minutes from the group.
