Guy Cotter was so concerned about the safety of Sherpa guides and porters through Mount Everest`s notorious Khumbu Icefall that he and another commercial guide operator hatched a plan.
Researchers have suggested that genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa.
The Sherpa has been designed "to aid the security forces in counter-insurgency".
A veteran Nepalese guide who has climbed the Mt Everest 19 times is missing along with two others, after an avalanche hit their expedition in the Himalayas.
Three Japanese climbers and a Sherpa guide were swept away by an avalanche at a mountain peak in Nepal and a helicopter has been sent to rescue them, a
Tourism Ministry official said.
