Mt. Everest Day? Thanks, I didn't know that.
Above, climbers and porters on a 1963 American expedition set off in their bid to ascend
Mount Everest. The team used 900 porters to carry 27 tons of supplies to base camp.
In the end six team members reached the summit with little more than their backpacks.
