Hastings further suggests that Gibson did not trust some of his pilots sufficiently - facts that have been disputed by other books and historians. I won't go into the details in the review - but the one belief in this is that Hastings could be trying to find a new take on what is a well told story in other books.
Hastings also goes into depth about the effects that the bombing had on the German war effort. Whilst of course the feet of Gibson’s men is never downplayed the actual effects of damage to Germany is exposed to not be as great as firstly expected. The crews of the bombers believed their mission was going to help speed up the end of the war and whilst it caused some damage and did delay things the main result was a huge loss of life to actually a whole lot of Migrant workers and some minor delays to manufacturing of no more than a few months.
For some other reviews that I've read of people with further knowledge of 617 Squadron and the Dambusters raid this book opens up questions that are perhaps factually incorrect. However Hastings is a very accomplished writer and a skilled narrator of a brilliant true life story and you can't take that away from the book. The chapter indeed which talks through the Dambusters raid itself for me was a non book down read.
If you have any kind of interest in the Dambusters raid then this is a great introduction to it and will give a very different view to the film of the same title.
