Three French adrenaline junkies boldly attempted to walk on a tightrope between two hot air balloons - with nothing but a parachute to save them.
Sebastien Montaz-Rosset, a member of the Skyliners team, and two other friends were hoping to complete the difficult challenge of walking from one hot air balloon to another without a safety harness.
In order to fulfil their dream, they headed to Spain to execute the thrilling stunt, with a support team up in the air to ensure everything ran smoothly.
The video shows the group of experienced parachutists and slackliners hoisting themselves up onto the extremely thin tightrope between the baskets at an altitude of around 10,000ft.
However, the experiment failed to pay dividends, with the footage showing two of the skyliners plummeting through the air at incredible speeds before deploying their parachutes. After failing to make it across, a third participant followed later on.
After landing, Montaz-Rosset insisted he would try again: "All of the Skyliners team were excited to put their skills to the test on such an amazing line. Thanks to the talent of the pilots, we came really close.
"We'll be going back again very soon to make it happen - watch this space!"
