Professional skater and performer Lukasz Malewski was doing a stunt at the Flic Flac circus in Duisburg, Germany when the incident happened.
The clip shows Lukasz getting his running take-off badly wrong and falling over before he has even got to a jump over the arena.
The momentum he has built up on the slope however means he takes off on his backside, sending him horizontal.
He is then seen flying high into the rafters in front of a packed audience before coming down – and managing to get one foot onto the landing ramp.
Lukasz desperately tries to grab a hold of the ramp but doesn’t have enough momentum and falls backwards over the precipice.
Spectators can be heard gasping as he drops 20ft to the ground with nothing to break his fall.
Another stunt performer on a scooter had spotted that the jump had gone awry and attempts to break Lukasz’s fall but doesn’t get there in time.
Lukasz discovered he had suffered a fractured wrist in the incident on December 22 after a second trip to hospital.
