““If the fitter climbers had been able to move at their own speed that day there would probably have been a process of natural selection. The front runners could have summited early, within an acceptable time frame and it would have become obvious that those who were at the back of the line were not going to get safely to the top and back. What, in fact, happened was that the climbers, particularly in Rob Hall's team, were forced to stay together, which held back the faster climbers. Everyone was now moving at a slow, dangerous pace. It inevitably meant there would be bunching at the choke points.””
