This video shows the terrifying moment that a daredevil's 115ft cliff dive nearly went tragically wrong, with the thrillseeker lucky not to suffer serious injury or worse as he plummeted into the water.
Jon Gleason took the plunge at at Birdsboro, Pennsylvania, leaping from a ledge 35 metres above the water below him.
Gleason was filmed by his friends as he took the jump and then tried to transition into a reverse spin in the air.
However, he evidently lost control - when he hit the water, his arms could be seen flailing helplessly as he panicked.
It's estimated that he would have been travelling at 55mph as he hit the water, given the height he had jumped from. Thankfully for Gleason, he had a friend in the water ready and waiting for him in case the stunt did indeed go wrong.
Reflecting on the attempt, he later said: "After the dive I experienced a pain in my knee and left pectoral muscle, both had swelling but nothing was broken or torn.
"It didn't go as pretty as planned, but it happened."
In many respects he was a lucky man. The impact from falling into water from a great height can cause serious injury, with people potentially suffering concussion and broken bones, and a risk of being knocked unconscious as a result of the speed of the collision.
Posting the video on Instagram, Gleason was understandably met with an array of comments. One friend asked him whether he had been hurt, to which he replied: "Nothing's broken."
Another person said the fall looked like it must have been at least 150ft, but Gleason claimed: "Our 200ft rope called it at 115ft but definitely felt closer to 150ft based on pain."
Given the attempted reverse spin, perhaps Gleason's next stunt should be attempting to emulate the incredible London gymnast Andrew Price, who went viral at the beginning of the year after performing a mid-air split and jumping through a hoop that had been thrown at him.
The circus performer and gymnast went viral after performing the spectacular feat on 13 January.
As a hoop was thrown at him horizontally, Price jumped and performed a mid-air split - called a 'straddle' - to get through it.
Andrew said at the time: "This trick doesn't have a name and it's the first time ever done as far as we know. A lot of professional hoop divers that we showed it to have said the same.
"The one in the video was my third attempt. I asked whether we thought it would be possible to pass through the hoop in a straddle jump, so we tried it out and it turned out pretty cool."
Something to aim for! Although maybe rest up first, Jon.
