A very interesting read that I finished not long ago was `Diary of a Spitfire pilot' byGranville Allen Mawer. It really was a diary and was only published in 2011 - long after his death. It covers flying in UK and later Darwin during the war. It gives an insight into the thoughts and feelings of the writer. Surprise ending.
Also `There's always Bloody Something' by Frank Bryant who travelled many times to Germany of an evening until he finally found himself on the ground there and locked away for safekeeping until the war was over. A very good read and highly recommended.
And `Bring back my Stringbag' by lord Kilbracken for a bit of nautical aviation.
