Anxiety-inducing footage shows the first time a US man went hang gliding. 

But it’s not the fact he took off from a 4000ft mountain edge that has our hearts racing, it’s because his instructor forgot to attach his safety harness.

Chris Gursky, who landed himself a fractured wrist, shared the vision on his YouTube.

On a holiday in Switzerland, the footage depicts him clinging desperately to the glider as the pilot attempts to land in a safe place.
