Celebrations have been held to mark the 60th anniversary of the first climb to the summit of Mount Everest.
Edmund Hillary and Tenzing Norgay completed the expedition to the world's highest peak in 1953.
The historic feat has since inspired many climbers to follow suit - including the men's sons, as Robert Hall reports.
