"The Nazi Plan To Bomb New York City."
Written by David Myhra, this one hour TV documentary features Oberst Siegfried Knemeyer's plan to obtain a flying machine capable of exploding a 5,000 pound conventional bomb over New York City which would have blankets of radioactive silica (sand) wrapped around it. The radioactive silica would have fallen on New York City like snow flakes causing radiation sickness and death leading the Nazi leaders to believe that they might then obtain a cease fire or some sort of condition surrender from the Allies. Knemeyer had set up a competition between three individuals: Wernher von Braun and his piloted A-9 rocket missile and its A-10 booster rocket, Eugen Sanger and his piloted, reusable, suborbital rocket bomber, and Reimar Horten and his six turbojet powered Ho 18A all-wing bomber. The documentary features on site interviews at the Horten workshop-Gottingen, Sanger workshop-Tauen, and von Braun's Peenemunde Experimental Rocket Center. Extensive computer generated color digital animation by Mario Merino is featured, and of course, on camera comments by David Myhra.

He played a major role in WWII for Germany and the USA. He was involved in inventing the B-52 Bomber.

Information from an ebay item WW2 German Luftwaffe Flight Computer DR2 Knemeyer.
This is a standard piece of Luftwaffe flight equipment, every pilot and navigotor would need one. It is officially called the DR2 Knemeyer. It is maker marked C. Plath Dennert & Pape Hamburg Altona. It is dated July 1938. The flight computer is used to calculate the effects of wind on speed and direction - dead reckoning. All the inside discs rotate, and the plastic pieces are still all in good shape. Some wear to paint on the metal disc on the outside.

Horten VII, W.-Nr. 29
Construction of the H VII took place at the Gottingen Bureau. The aircraft's wings, which were of wooden construction, were built by the Lln 3 workshop, while the center section, which was of welded tube steel construction with Dural skinning, was manufactured by the Peschke Firm in Minden. The aircraft made its first flight in May 1943 with Heinz Scheidhauer and Walter Horten on board. The aircraft had originally been conceived as a flying test-bed for the Argus-Schmidt pulse-jet engine after the H V had proved unsuitable for the role. When this plan was abandoned it was proposed as a fighter training aircraft. The H VII was powered by two Argus AS-10-SC engines drivinq two-bladed constant-speed propellers via extension shafts. The aircraft featured a fully retractable twin nosewheel under-carriage. So-called "wingtip rudders" were used in place of a conventional rudder. The aircraft was assigned the RLM-Number 8-226. The aircraft's pilots were Heinz Scheidhauer, Erwin Ziller and Walter Horten. In autumn 1944 Oberst Knemeyer demonstrated the H VII to Hermann Goring at Oranienburg, after the Reichsmarschall had expressed a desire to see a Horten aircraft in action.
Knemeyer was the RLM flight-test chief and was favorably disposed toward the aircraft developed by the Horten brothers. Goring, a former WW I fighter pilot, had not participated in the later gliding boom and was unfamiliar with the aircraft which emerged from the program. He wanted to see the aircraft fly on one engine, which Heinz Scheidhauer did without any hesitation. The Reichsmarschall was impressed; the Peschke Firm received an order for twenty examples.
Construction of the H VII V2 began in 1944, but the aircraft had not been completed when the war ended. The V3, which was to see the "wingtip rudders" replaced by spoilers above and below the wings, as on the H IX, progressed no farther than the manufacturing of various components.
In February 1945 Heinz Scheidhauer flew the H VII to Gottingen. Hydraulic failure prevented him from extending the aircraft's undercarriage, and he was forced to make a belly landing. The resulting damage had not been repaired when, on April 7, 1945, US troops occupied the airfield. The aircraft presumably suffered the same fate as the H V and was burned.
