In August, 2005, Tomaž Humar was trapped on a narrow ledge at 5900 metres on the formidable Rupal Face of Nanga Parbat. He had been attempting a new route, directly up the middle of the highest mountain face in the world - solo. After six days he was out of food, almost out of fuel and frequently buried by avalanches. Three helicopters were poised for a brief break in the weather to pluck him off the mountain. Because of the audacity of the climb, the fame of the climber, the high risk associated with the rescue, and the hourly reports posted on his base-camp website, the world was watching. Would this be the most spectacular rescue in climbing history? Or a tragic - and very public - death in the mountains?
