Query: Battling for life and freedom at the height of Mt. Everest.

This mission by mission diary account of a brave B-17 crew is a book that is very hard to put down! Flying higher than Mount Everest while battling with german flak, fighters, and frostbite, this book is proof of our "Greatest Generation" in the grips of war. We shall forever be indebted to the service of these and all other WWII veterans. God bless you all!
