Surviving Hell: A POW's Journey by Leo Thorsness
A very inspiring account of an Air Force Major who was shot down over North Vietnam in 1967. His book is short---only 127 pages---but I found it very inspiring. This book made me chuckle more than once which is ironic given the subject matter. He focuses a lot on the banter between him and his cell mates, as well as the little things which kept them sane while in captivity. It's amazing how they kept their sense of humor intact over all those years of torture. It really solidifies the importance of humor in the face of apparent hopelessness/danger.
For those who have read this book or will read this book, my favorite chapter is chapter fifteen. I won't saying anything more.
EDIT: I should also mention that he received the Medal of Honor for a mission he flew just days before he was shot down.
