Under the Nazi regime, fringe sciences were legitimate areas for research and development, resulting in funding for unorthodox ideas and projects that were too outrageous for other governments. During the last six months of the war, it seemed obvious the Germans had been crushingly defeated, but in spite of the military situation, Hitler continued to believe that victory would be achieved through the use of Wunderwaffen ("miracle weapons"). Separating the cutting-edge science from impossible creations, Michael FitzGerald discusses Nazi flying saucers, the V-1 flying bomb, the V-2 rocket, and the V-3 heavy gun, and assesses the German nuclear program.
