In the history of warfare there have been a catalogue of inventions that have changed the way battles are fought. The catapult, the longbow, the cannon, the machine gun. But one weapon changed not only the battlefield, but war itself. It extended the scope of military conflict to the far borders of entire nations and unleashed a terror the world had never known. That weapon was the Bomber. It emerged in the early twentieth century as the most potent symbol of modern war. The Bomber gave rise to images that define World War II; sticks of bombs tumbling from the bellies of B-24s, razed buildings, the mushroom cloud. No weapon or weapons system has received as much investment, manpower or innovation - or been so destructive. Using meticulously researched archival footage and expert insights, we examine the strategies, technologies, effects on humanity and the game changing planes developed over World War II.
