I said to Scott that the ascent seemed to be going slowly and that I was concerned descending climbers could possibly run out of oxygen before their return to camp IV.
I explained I wanted to descend as quickly as possible to camp IV in order to warm myself and gather a supply of hot drink and oxygen in the event I might need to go back up the mountain to assist descending climbers.
I told them, you can succeed - it's not likely the first time, maybe 25 per cent, but you CAN succeed. You can also die. By April 16 they had already been to camp III, well ahead of most teams.
