Team One have summited but the mountain is so crowded with other climbers that they get caught in yet another queue as they attempt to get down. It's turned into a marathon climb of nearly 18 hours with climbers suffering frostbite in the bitter cold. Now it's Team Two's turn at the summit and they set off two hours early in an attempt to beat the queues, but it means an extra two hours in the dark on one of the coldest days anyone can remember. Mark Inglis makes history as the first double amputee to summit, but two climbers who are struggling mutiny when Russell orders them to turn back.
