Query: Wonderful book!

This is a wonderful book that documents five separate stories ofB-17 "Bomber boys" from WWII.Two of these stories, one an amazing story of survival and the other about evading capture behind enemy lines, are perhaps the most interesting stories of individual exploits I have ever read. Not just from the war, but period.This book is a great read and a precious documentation of World War II sacrifice and heroism. The author is to be commended for capturing and publishing these stories while there is still time.
