As someone who has studied the Battle of Britain in copious detail these many years past I can say this book adds nothing to the sum of knowledge. What it does superbly is give people who are not specialists as I am a fine summary of what it felt like to be a young man in the RAF charged with the onerous duty of combating the Luftwaffe's formidable onslaught upon the British Isles. In sweeping and breathtaking prose Mr Bishop steers the non specialist reader into the skies with such vividity the non specialist must feel he or she is actually up there. For non pilots this must be a strange yet also exciting sensation. Courage, courage and courage. These are the qualities that sustained these young men. Also humour as Mr Bishop amply explains. To specialists such as me there are minor quibbles and flaws, of no interest to the run of the mill reader. Mr Bishop is wrong most emphatically in his assertions regarding the turning circles, acceleratory capacities, air frame to power inverse ratios and aerlion spivets of the Spitfire in comparison to the lesser known Hurricane. To specialists such as myself these are irritations. To the general public they will not detract from what is a magnificient work and a worthy tribute to the men who saved us from the German armada awaiting across the Channel had the RAF faltered. To all who doubt our debt I say they should read this wonderful book.
