Those pPruners still sending their requests to Santa should consider Combat Crew by John Comer, a B-17 flight engineer/top turret gunner who kept a journal of the 25 missions he flew in 1943 from Ridgewell, at a time when the casualty rate from his base was 80%. His writing matches anything I have read on the bomber offensive and shines far above most accounts of USAF operations. It's available from Amazon as paperback or Kindle, and I could not put it down. Comer describes not only the experience of flying on operations but also what went through the minds of his comrades as they watched their friends plunging to their doom. An aviation classic.
