I recently bought a book written in the 1970s called Disturbing the Universe by Morgan Freeman for about 35p in a charity shop. I knew of him from the connections with Rudolf Peierls and Richard Feynman.
There was a short chapter on his experiences in ORS at Bomber Command in WWII. I was really surprised with his findings concerning, the low survival rates from damaged aircraft, the high level of LMF, the conclusion that eventually previous experience was not a deciding factor in survival and the reluctance of aircrews to relate their operational experiences.
I would recommend reading his views on the Bomber War.
