A passenger enjoying a civilian joyride accidentally cut the trip short when he ejected himself from the plane after grabbing the eject lever while trying to brace himself.
The passenger was flying in a Pilatus PC-7 Mk II with an air force pilot friend, The Daily Mail reported.
He was instantly blasted 320-feet into the sky by the rocket-powered chair, before floating to the ground with an automatic parachute, the paper reported.
Air Force officers quickly deployed a helicopter to retrieve the passenger after his fall 80 miles south of Cape Town, South Africa.
The pilot of the craft, Captain Gerhard Lourens, is a long-time member of the Silver Falcons air force air display team, according to The Daily Mail.
