This is one of the best combat memoirs I've yet read. Comer was an aircraft mechanic stationed stateside with the United States Army Air Force (USAAF) in November 1942, when he volunteered for combat service as a flight engineer/gunner.
After completing his training, Comer ended up in Britain in July 1943 with a B-17 bomber group in the 8th Air Force. He arrived at a time when U.S. bomber groups were experiencing high casualty rates from flying missions over German-occupied Europe. Each member of a bomber group was required to fly 25 missions before he would be eligible to return to the States, job well done. Comer conveys so tellingly the pressures encountered with each mission, the way weather affected operations, and the importance of teamwork among crews as a factor toward enhancing one's chances of survival --- and sanity --- as one edged ever closer towards the completion of 25 missions. (Thank you, A.L. for recommending this book.)
