Once there was a war.. A war like none other.. A war cloaked in darkness, lit only by the flash of flares and searchlights, the explosions of bombs and the blaze of burning planes. So begins this series of the deadly war fought in the dark skies over Europe in World War II. For the first time in history of human conflict, a war was fought by men and machines in the air at night. Veterans from both sides recount the commonplace bravery and horror that they faced on a daily basis. The complex tactics that evolved and the race of competing technologies are related by graphic images and animation. The war had become not only battle between men but also a struggle of science and technology.
