A double amputee who conquered Everest has spoken of the agonising decision not to help a man who died on the mountain.
Mr Sharp died as he made his descent
Experienced climber David Sharp, 34, of Guisborough, Teesside, was on his way down from the world's highest mountain when he got into difficulties.
New Zealander Mark Inglis, said his party saw Mr Sharp as they climbed the 29,028ft (8,500m) peak.
He said there was nothing they could do for him.
Mr Inglis, 47, last week became the first double amputee to reach the top of Everest. His legs were amputated below the knee after he suffered frostbite during an expedition in 1982.
Speaking to the Close Up programme on New Zealand television, Mr Inglis said: "The trouble is that at 8,500m (27,887ft) it is extremely difficult to keep yourself alive, let alone keep anyone else alive.
"It was like 'What do we do?' We couldn't do anything. He had no oxygen, no proper gloves, things like that.
"On that morning, over 40 people went past that young Brit. I was one of the first."
Mr Sharp, who had climbed alone, was on his third climb of Everest when he apparently ran out of oxygen about 984ft (300m) below the summit as he made his descent.
Other climbers found his body in a cave last week, 1,000ft (305m) below the summit.
