$this->bbcode_second_pass_quote('jboogy', 'H')i Plantain , I didn't know that. Every photo I've ever seen of Hillary climbing the mountain shows him and his party not wearing oxygen masks , even the ones with him at or near the summit, I wonder how he knew he'd need bottled oxy. since he was the first to go that high. Were previous attempts failures because the climbers couldn't breath properly? How do the sherpas do it without oxy.? Can you condition your body to perform at significantly lower oxy. levels? I wonder if NFL teams that travel to denver to play are at a disadvantage.
You wonder how he knew he'd need oxygen? He was far from the first to go that high in our atmosphere. Think about where aviation was by the 1950's...
For that matter, balloonists had climbed well past that altitude (and lost consciousness in the process) by the 1860's. This was nothing new for mountaineers to discover. From my flying days I know all about hypoxia, which imparts euphoric feelings and has a profound effect on judgement. The meaningful measurement is called "time of useful consciousness" with the emphasis on useful. Without adequate oxygen your judgement would be almost as bad as a politician with taxpayer money and the power to spend. Almost.
I've climbed Pike's Peak (14,110 feet) and felt the same hypoxic symptoms I felt in the chamber when I was a student pilot. (Had a great instructor who owned a vertigo chair, got us into Longmont FAA Air Traffic Control and an altitude chamber!)
Your endurance IS a little better if you train at altitude - that was a factor in locating the original Olympic Training Center here in Colorado. And yes, we see NFL players sucking wind here sometimes, particularly the chubby ones on sea level teams...
The Everest pictures you've seen without masks were partly due to the fact that the masks had to come off in order to operate the camera. Hillary wrote about removing his mask to take pictures from the summit. I have a book of photographs from that expedition but there are none of Hillary atop the mountain because his Sherpa Norgay didn't know how to use a camera! My bet is the masks went right back on after pictures, particularly given the work their muscles were doing. I'm all about adventure and calculated risk, but scaling Everest without oxygen is a bit much!
I've admired Edmund Hillary since childhood. He had an innate sense of adventure that I relate to. He went on to summit many other mountains and eventually become the first human to stand on both poles and Everest. I liked his mind as well - exemplified by the modesty and understated Kiwi pluck in his first words upon descending (to his friend George Lowe) "Well, George we finally knocked the bastard off."
