London, Apr 14: Dare-devil Simon Brentford leapt off UK's highest vertical sea cliff at 1,125ft above sea level and landed safely, reports Daily Mail.
For Brentford it's no mean feat, and he'll take it one step further by jumping off and free falling before eventually using a parachute to land safely.
Brentford leapt off St John's Head, or Big John as it is known locally, in Orkney a few weeks ago and has possibly become the first person in the UK to do it.
The skydiver and base jumper is known in the UK for his daring stunts and was the first to jump from Sron Ulladale in the Outer Hebrides last year.
Brentford took his friend Adam Bibby along to film the jump and also attached a camera to a helmet so viewers could get first hand experience of what he sees.
The footage shows him making his way up the cliff on the Island of Hoy before switching to the head camera where he can be seen teetering on the edge of the cliff.
He jumps off before eventually releasing the parachute and steers himself to safety, landing on a tiny rock below.
The sport, which would be terrifying for most people, has become so popular its participants even tailor-make wingsuits to allow them to plunge through the air within just a few feet of sheer rock faces.
Another favourite is to jump thousands of feet up using a breathing apparatus to cope with the lack of oxygen.
But one of the craziest of all would have to be base jumpers, like Brentford, who freefall from clifftops before opening a parachute.
However, it is not a sport without risk and last month a man who jumped off Arizona's Supersition mountains in the U.S had to be rescued after he leapt off a 600ft cliff with his parachute on backwards.
He only survived because he drifted into a crevice before ending up perched on a tiny ledge. Luckily he was able to call for help using a mobile phone.
Base is actually an acronym that stands for four categories of objects which the participant can jump from: buildings, aerials, spans - for example bridges - and earth.
