Tomaz Humar had spent nearly a week huddled on a ledge six-thousand metres up Nanga Parbat, the world’s ninth highest mountain. He was held in his precarious position by ice screws and ropes. The temperature inside his sleeping bag was minus five degrees Celsius. Repeated attempts to rescue him failed because of snow storms and avalanches. But on Wednesday two Pakistani military helicopters managed to fly close enough to his perch for one of them to dangle a line to him.
    There was nearly a disaster as the Slovenian climber was unable to detach the ropes holding him to the mountain. Luckily they snapped as the helicopter flew away from the peak and after thirteen minutes Tomaz Humar was back in base camp. He is said to be suffering from the effects of cold and hunger but otherwise he’s well.
    Tomaz Humar is famous for his solo assaults on some of the world’s toughest climbs. It was the second time he had tried to get up the Rupal face of Nanga Parbat. His earlier attempt also failed because of bad weather.
