Edmund Hillary wrote "High Adventure" about a year after his climb, and a it's a great description of just how things were done in those days! It's a very easy read too, in a boys-own-adventure style.

Speaking of aerial photos though, Over The Himalaya (http://www.amazon.com/Over-Himalaya-Koichiro-Ohmori/dp/09385...) has some staggering photos from the region if you like that sort of thing. Out of print, but worth tracking down.
