English mountaineer Andrew 'Sandy' Comyn Irvine (1902 - 1924) who took part in the third British expedition to Mount Everest. Both he and his climbing partner George Mallory disappeared near the summit. Mallory's body was found years later but Irvine's remains still have to be discovered.
George-Mallory & Edward Norton. Could todays climbers replicate the early days of climbing on MT. Everest with early equipment?
Mount Everest. Climbers sometime stumble upon men and women who are dying on the mountain but have no way of helping them so they must leave them to die. Two climbers found this woman alone dying yelling, "Please don't leave me", but were forced to continue on and let her die as they had no means to help her and staying would risk their lives. Years later, they saved up enough money to finally return and give her a proper burial.
