Freeman Dyson tells his own story in A Failure of Intelligence, one of the most fascinating articles I have ever read. He deals with the maths of calculating collision risk v. the benefit of swamping the target and its defences, the philosophy of the lightened Lancaster, and above all the failure to appreciate the Luftwaffe's upward firing cannons or Shragemusik until after the war. I intended to summarise this long article for the Brevet thread but publishing the two books of our late departed and much loved Danny 42C took most of my time last year. Anyway, I'm sure you will enjoy this fact-packed story:
