Fighting over the beaches of Dunkirk and in the Battle of Britain, guarding the night skies during the perilous months of the Blitz, pioneering electronic countermeasures, and serving air-sea rescue roles all around our coasts, the Boulton Paul Defiant played a vital part through most of World War II, finishing it in the important target-tug role. The Defiant is rightly considered Wolverhampton’s highest profile contribution to the war, and the most important product of Boulton Paul Aircraft. This book celebrates the contribution of the Defiant to the war in more than 200 illustrations, most from Boulton Paul’s own archives, and many never published before. It exposes some of the false myths attached to an aircraft held in great affection by many of its crews.
