Probably the best book I've ever read about the experiences of Bomber Command aircrew in World War II. Author Bruce Lewis himself was a veteran of 36 operations as a Wireless Operator in Lancasters with 101 Squadron. Each chapter of the book covers a different aircrew position, with the experiences of one or more aircrew vividly described, with a special bonus being the diary of a pilot under training, which is just fascinating. Some of the aircrew served in ordinary day to day squadrons, but operations inserting SOE agents, a bomb aimer's experience in 617 Squadron later in the war, and a Medal of Honor mission for an American ball turret gunner are great highlights. Although mostly about RAF operations, Lewis includes a chapter about an American B-17 copilot and a chapter about American air gunners (including the MOH op mentioned above). Absolutely riveting reading.
