Jaco van Gass, a British soldier from South Africa, lost an arm in Afghanistan. That’s not slowing him down a bit. He plans to climb Mount Everest, making use of a prosthetic arm that he helped design himself.

He said: “I came up with the idea to attach an ice axe to one of my prosthetics, so I kind of challenged the guys at Headley Court to see how we could get this done.”

Van Gass bought a regular ice axe and staff at the centre sawed off the double-sided head, then welded and bolted it to a specially adapted prosthetic made of carbon fibre and plastic.
