70 عاماً على الوصول الأول إلى قمة إيفرست
May 29, 2023 - في 29 أيار (مايو) 1953، أصبح إدموند هيلاري والمتسلق النيبالي تنزينغ نورغاي أول من يتسلق أعلى جبل في العالم، مستخدمان أحدث التقنيات المتوافرة في ذلك الوقت. ومنذ ذلك الحين، وصل إلى قمة جبل إيفرست أكثر من 11.000 متسلق.
The success of the British expedition, led by John Hunt, was attributed to the use of excellent oxygen apparatus and protective gear.
Special oxygen equipment of two kinds were employed – an open circuit system, by which a certain percentage of fresh air is absorbed as well as pure oxygen, and a closed circuit system where the mountaineer receives 100 percent oxygen from the cylinder.
Assault boots were also designed to be lighter and provide better insulation against the harsh conditions.
The science behind survival in an extreme environment has improved significantly since then, with today’s equipment prioritising ultralight and highly efficient gear. Ice axe handles, for example, are now made of lightweight metal instead of wood. Everest climbers in the 21st century often carry half the weight of Hillary’s pack load.
With advancements in technology the world’s highest peak has become a favourite destination for wealthy tourists. By 2022 more than 11,000 people had reached the summit, sometimes hundreds in a single day.
