James Lee jumped from a plane at a skydiving site in Wiltshire, and after being in freefall for just a few seconds a fellow jumper hit the back of his head at very high speed.

He was completely knocked out and was rescued by quick-thinking friends who noticed that something was wrong – they grabbed hold of him, moved him into a safe position and deployed his parachute. He started regaining conciousness shortly after, and luckily landed safely, without any memory of what had happened.

The other skydiver landed fine with a small cut and imprint of the camera button from the back of James’ helmet – and one very sore leg!
