Weather was clear and calm. The route was very busy. Straightforward climb. Good views. Group spent about half an hour on the summit. They descended to C4, where they arrived at 11 am and rested for an hour and carried on to C2. Kobold arrived at 5 pm: Ugyan and Casserley arrived at 8 pm. Ugyan was having troubles breathing at the bottom of the Lhotse Face, where Casserley had met her. She seemed to have tracheitis and at about 11 pm in C4, she had the feeling that she would suffocate. She told her husband Mike Kobold and all of a sudden, she collapsed and turned blue. Casserley fought for her life and with advice from Monica Piris (Russell's doctor), who he talked to over the radio; she came around and seemed Ok. Casserley gave her IV fluids and she was able to sleep. The next day, they all descended to BC. Kobold and Ugyan stayed for another couple of days at BC and then walked to Pheriche and flew back to Kathmandu. 25th summit team left C4 at 11:30 pm on 24th May. Weather was clear and it was not very busy on the route. Straightforward climb. Good views from the summit. They spent about 20 minutes on the summit and descended to C2, where they arrived at 3 pm - apart from Ramsden and Casserley, who arrived at 6:30 pm. Feldman reached C1 on 20th April. On his second trip to C1 he fell into a pool of water in the Khumbu icefall, which put him off the climb. He left the expedition on 25th April. Todd stayed at Base Camp to orchestrate the expedition.
