An experienced base jumper is lucky to be alive after he smashed into a mountain during a 4,000ft dive.
The adrenaline junkie, known only as Karl, recorded the horrifying moment he jumped off Monte Brento, Italy, on August 16.
In the footage, he performs a mid-air flip - but when he opens his parachute - he realises something has gone horribly wrong.
Karl struggles to deploy the canopy correctly as he desperately pulls the cords to straighten it.
