At one o'clock in the afternoon, the British climber Peter Kinloch was on the roof of the world, in bright sunlight, taking photographs of the Himalayas below, "elated, cheery and bubbly".
But Mount Everest is now his grave, because only minutes later, he suddenly went blind and had to be abandoned to die from the cold.
As the team descended, Mr Kinloch's guides noticed that he seemed to lose co-ordination. He would slip and stumble, then resume walking normally. After an hour, he made a surprising request to the team leader, David O'Brien, to be shown how to get down the ladders. At first he said he was having difficulty seeing, then he admitted that he could not see anything.
