A splendid work. A detailed account of two important wartime fighter aircraft enlivened by the words of those who flew them. -- Len Deighton The epic struggle between the Spitfire and the Messerschmitt 109 upon which so much of western civilization depended in the summer of 1940 has found the ideal biographer in David Isby. I write "biographer" because, like the men who flew these remarkable fighter planes, Isby sees them in almost human terms, transcending the mere mechanical. -- Andrew Roberts, author of The Storm of War This is an important book on an enduring subject that should satisfy experts and newcomers to the field alike. -- Nick Cook, author of The Hunt for Zero Point and former Aviation Editor, Jane's Defence Weekly
