Paraplegic thrill-seeker Christine Rougoor, 24, fulfilled a lifelong dream by taking part in the challenge.
The incredible feat was captured on camera and show Miss Rougoor yelling with joy during the jump.
She said: "It gave me a couple of seconds of freedom from any worries and thoughts.
"I would do it again in a heartbeat.
"The minute I got back, I begged them to push me back over."
The one-minute film shows Miss Rougoor, who is paralysed from the waist down, on a bridge in British Columbia, Canada.
Helpers then hoist her onto the rails before chucking her wheels-first over the edge.
She lost the use of her legs back in 2008 when she was involved in a biking accident in Florida.
Christine was in a coma for three weeks after the crash before waking up on Christmas Day.
Since then she has trained as an art and French teacher and raised money for good causes, including Wheels in Motion.
The amazing jump was made possible by 9Lives Adventures, who do extreme sports for disabled people.
Founder Karim Ladki said: "I normally tell the first-time jumpers to stay in the chair as it provides a good back support and keeps you upright.
"This also prevents any blood from moving around the body too much, furthermore preventing any light-headedness or black-outs." - theSUN
