1924 British Mount Everest expedition
The 1924 British Mount Everest expedition was—after the 1922 British Mount Everest expedition—the 2nd expedition with the goal of achieving the first ascent of Mount Everest. After two summit attempts in which Edward Norton set a world altitude record of 8,572.8 metres (28,126 ft), the mountaineers George Mallory and Andrew "Sandy" Irvine disappeared on the third attempt. Their disappearance has given rise to the long-standing speculation of whether or not the pair might – under a narrow set of assumptions – have reached the summit. Mallory's body was found in 1999 at 8,156 metres (26,760 ft), but the resulting clues did not provide any conclusive evidence as to whether the summit was reached.

1922 British Mount Everest expedition
The 1922 British Mount Everest expedition was the first mountaineering expedition with the express aim of making the first ascent of Mount Everest. This was also the first expedition that attempted to climb Everest using bottled oxygen. The expedition attempted to climb Everest from the northern side out of Tibet. At the time, Everest could not be attempted from the south out of Nepal as the country was closed to Western foreigners.
