"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, who 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."
I've done some stupid ass things in my life but this would take the cake. If memory serves, the eject levers are usually pretty much out of the way, but I am unfamiliar with this particular aircraft.
