Book excerpt: Volume II of this mammoth reference work covers the years in which the League of Nations failed because of the emerging dictatorships in Germany and Italy and the expansionist policies adopted by Japan. Britain was still reeling from the consequences of World War I and the RAF was sadly far behind the other major world powers in aircraft design, still relying on bi-planes that were direct descendants of World War I thinking. It gradually became apparent that, despite UK government dithering, the RAF needed to develop new aircraft, engines and increase production to confront the bully-boy tactics of the Axis powers. As the turn of the decade approached extraordinary measures were taken to enable RAF to defend Britain's skies and this her freedom. As with Volume 1, this book covers every conceivable part of the RAF's history through these pre-War days.
