An adrenaline junkie hangs onto his best friend's arm while on the "longest highline" in the US.
Filmed in November 2018, Friedi Kuehne and his friend both edge across a highline set up in Utah canyon.
Kuehne's friend then unclips his harness before lowering himself down. He then lets go of Kuehne's grasp before promptly deploying his parachute.
