The art work on the cover is not that great, but I guess you are not supposed to judge a book by it's cover.
Risking further infections on my virus-raddled computer.... 'Bomb Run' is a well-researched novel first published in 1971 ( I've got a paperback copy with a nice lanc/Me110 cover ). This was Dunmore's first novel ( he later went on to write the semi-official history of 6 Group, 'Reap The Whirlwind' so he knows his stuff ). It's OK to read but the characterisation is a little wooden - it's no match for Len Deighton's superlative 'Bomber' , for instance. Back into quarantine for me.....
