Adventurers continue to seek new firsts in unusual ways, which keeps getting harder as people push the envelope more and more.
Last October, Joby Ogwyn entered the record books by being the first man to jump from a plane circling over Mount Everest. He was clad in a custom-made wingsuit, those costumes that allow humans to glide like flying squirrels, before landing with parachutes.
From 29,000 feet above sea level, Ogwyn glided into the history books and plans to make the trip again, this time with an IMAX camera to film the descent.
Although it may seem like the flight would be the most dangerous part of the trip, it was when Ogwyn's parachute lines twisted up as he attempted to land at base camp that it looked like he may die. Base camp is at 17,000 feet.
Cameraman Barry Holubeck went along to film the flight and got blown off course in the jet stream after exiting the plane. For training, they jumped out of helicopters to fly along the Matterhorn and Eiger in Switzerland.
Their custom-made X-wing suits included small oxygen masks built in. They wore insulated clothing under the suits for the extreme cold. They had small HD cameras built into their suits to capture the flight.
