Jeb Corliss, a professional base jumper, was seriously injured when he crashed into rocks during a 3,500-foot freefall drop at Table Mountain in Cape Town on Monday. According to Park officials, the jump was unsanctioned, executed by Corliss without permission.

Corliss was airlifted to a hospital, where he sustained serious leg injuries during the drop, according to The Daily Mail, which he was filming as part of a documentary for HBO.

Table Mountain National Park officials told the Cape Times the jump was conducted without permission from Park officials by the BASE jumper, an acronym for buildings, spans, antennae and earth formations, or all the places jumps can originate.

The danger associated with base jumping does not allow us to issue permits. He did not have permission. We will definitely fine him and possibly press charges, spokeswoman Marle Collins said.

Caught on video, 35-year-old Corliss is seen with another base jumper wearing wingsuits just about to jump from Table Mountain in Cape Town. While gliding over mountains of rock, Corliss suddenly begins to plummet before clipping his legs on rocks and shouting in pain.

It could have been a strange gust of wind, it could have been that he got too close to the mountain, said fellow base jumper Joby Ogwyn who was there during the accident.

Corliss is in stable condition with broken legs, according to The Associated Press. Doctors said the only reason Corliss survived was thanks to his emergency parachute he deployed moments before clipping the rock, The Daily Mail reported, though he will still need surgery.

I feel better than I've ever felt, Corliss told the Cape Times from the hospital.

Corliss, one of the world's foremost and best-known BASE-jumpers and wingsuit pilots as his Web site states, has been base jumping for 14 years. Corliss has conquered the Eiffel Tower in Paris, the Petronas Towers in Kuala Lumpur and the Golden Gate Bridge in San Francisco.

Jeb Corliss, once the host of Discovery Channel's Stunt Junkies, was banned from New York City's Empire State Building in 2006 when police convicted him of reckless engagement for base jumping.
