Former Staff Sgt Charlie Linville, 29, from Boise, Idaho, is using a specially designed metal foot outfitted with a climbing boot and another one with crampons in his quest to conquer the 8,850-metre summit next month.
"My message is anything is possible. It is just not me being an amputee, but anyone sitting on the couch around the world that has problems you can overcome life, it is just how determined you are," Linville said in Kathmandu today, on his way to Tibet in neighbouring China, from where he will set out on Everest.
He retired from service and has been climbing since with The Heroes Project, a nonprofit organisation that helps wounded veterans.
Everest would be his highest and toughest mountain that he has attempted to climb. His quest last year was thwarted following the deaths of 16 Sherpa guides in April, the beginning of the climbing season, when an avalanche swept down. At the time, Linville was at the base camp at 5,360 meters.
"The only difference between me and any climber on the mountain is that I am missing one limb and I have to deal with metal," he said.
