Sixty years after Sir Edmund Hillary and Tenzing Norgay reached the summit of Everest, climber after climber has achieved the feat.
But the experience of an Everest climb in 2013 is undoubtedly poles apart from that of Hillary and Norgay.
In their expedition, climbers hauled loads of nearly 44lbs each, with food including tinned fruit and sardines.
Today, adventurers enjoy lightweight, state-of-the-art gear, with packs sometimes weighing less than half of Hillary’s load, to help them in the arduous task.
They have swapped heavy steel equipment for aluminium equivalents, and canvas tents for modern, purpose-designed replacements designed to stand up to Himalayan winds.
Twenty-first century Everest climbers can even send text messages and make calls from the summit, using far lighter and more reliable technology than the heavy radios used by Hillary and his team.
