This includes one of my favorite details, which is the coded message sent to confirm the ascent:
>Snow conditions bad stop advanced base abandoned yesterday stop awaiting improvement
Wikipedia[1] has the breakdown, as well as the rest of the code for other individuals[2]:
>Snow conditions bad" was the agreed code to signify that the summit had been reached; "advance base abandoned" referred to Hillary and "awaiting improvement" referred to Tenzing.
One thing I always think about with these kinds of codes: what would they have said if the snow conditions were actually bad and they had to abandon their base?
