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.
