In recent years Don Williams has stuided the role of Royal Australian Air Force in the Pacific War. He was surprised to find that no book telling the complete story of Australia’s own wartime emergency fighter, the Commonwealth Aircraft Corporation Boomerang, had been published. Don decided to fill this gap by writing a book dedicated to the Boomerang. He is also a keen amateur photographer and is pleased that some of his photographs are included in the book. Sound research and writing were foundations of Don’s career as a policy analyst and these skills were further honed when he completed a mature age PhD.
