Russian climber Alexander Gukov began his long journey home when an EMERCOM charter plane left Islamabad on Saturday. He will continue his rehabilitation in a Moscow hospital. Gukov was stranded over 6,000 metres (20,000 feet) above sea level for six days after his climbing partner Sergei Glazunov fell to his death. He survived bad weather conditions and repeated avalanches by building a... Еще cocoon in the snow. On the seventh day, better weather conditions meant a Pakistani army helicopter was able to mount a rescue. Gukov was quickly rushed to a military hospital, suffering from severe frostbite and hallucinations. The 7,145m-high Latok I in Pakistan's northern Karakoram range is widely regarded to contain some of the world's most difficult high-altitude mountain climbing. The north ridge has never been scaled, although Gukov and Glazunov came close.
