Over a dozen Nazi jet and rocket planes flew before the close of the war and literally hundreds more designs were on the drawing board. We tell the story of planes such as the tiny HE 162 jet interceptor, built in deep underground caves and flown by pilots of the Hitler Youth. Of the amazing Horten Flying Wing jet bomber designed to attack New York. We reveal plans by Kurt Tank, the designer of FW-190, for a jet fighter armed with air-to-air missiles - a plane he later built for Argentina's General Peron. And we show for the first time the plans for a jet version of the Stuka dive bomber and how it might have reversed the tide of battle on the eastern front. Using specially commissioned computer graphics, never seen archive footage and interviews with aviation experts, we bring back to life the secret Luftwaffe planes of the second world war.
