Air Vice-Marshal Don Bennett is best known as the Australian commander of the Royal Air Force’s elite Path Finder Force in the Second World War. His drive, determination and passion for excellence saw him play a principal role in prosecuting the bombing campaign against Nazi Germany. Yet, the full story of his life has never been comprehensively explored. Few can recount his exploits as a pioneering aviator, or know why he was regarded as the most technically brilliant airman of his generation. Fewer still know the man’s background, interests, passions and obsessions, or what drove him to his many aviation achievements. Relentless Skies, Volume 1: The Most Efficient Airman, explores Bennett’s life up to 1942. New light is shed on his early years, pilot training, participation in the Centenary Air Race, setting world records in the seaplane Mercury, the 1940 rescue of the Polish General Staff from France & how he survived being shot down whilst attacking the Tirpitz. Binding together this series of extraordinary events & achievements is, crucially, an exploration of Bennett’s character & how it influenced his choices, relationships and approach to leadership. Unparalleled access to the Bennett archive has enabled biographer Ian Campbell to reveal the many facets of one of Australia’s greatest, and often misunderstood, wartime leaders.
