Summary:
This collection contains interviews with Reimar and Walter Horten that were recorded by David Myhra.
Scope and Contents:
This collection contains interviews with Reimar and Walter Horten taped by David Myhra, author of The Horten Brothers and Their All-winged Aircraft. It includes various topics relating to the Hortens, and comprises sixty original tapes donated by Myhra, as well as two copies made by NASM, one consisting of sixty-one master reel-to-reels, and another of 120 reference CD-Rs. A box of "transcripts" for some of the tapes is also included in the collection, although it is unclear which transcripts go with which tapes.
Arrangement:
This finding aid was generated from the original recording labels. Mr. Myhra labeled most of the tapes, but each group of tapes is labeled differently. Dates are included when provided but the list does not follow a chronological order, which is irrelevant anyway considering the wandering nature of Mr. Myhra's interviews. The finding aid is arranged in groups, which roughly correspond to each set of interviews. In addition, NASM has given each tape a new number which runs consecutively from one through sixty. The original number given by David Myhra is listed in the description of each tape. The new NASM numbers for the original tapes correspond to the NASM reel numbers and the NASM CD-R numbers as to make locating each copy more convenient.
Biographical / Historical:
Reimar Horten and his brother Walter, two largely self-taught aircraft designers, were born in Bonn, Germany; Walter on March 3, 1912, and Reimar on March 12, 1915. Their interest in aircraft began as early as 1925 when they joined a fliers' club in Bonn. In 1932 Reimar and Walter commenced work on their first piloted all-wing sailplane the Ho I. The basic concept of the flying wing dates from the dawn of aviation, but the Horten brothers became the virtuosos of this aircraft. The Horten all-wing sailplanes were gliders without a fuselage or tail section. Because the fuselage and the tail section of a regular plane produced 30% to 50% of an airplane's drag, the benefit of the sailplanes was clear. During the time preceding World War II the brothers improved upon the Ho I glider, creating other models including the Ho II, Ho III, and the Ho IV--none of which had any engines. Reimar and Walter joined the Luftwaffe (German Air Force) during the course of the war where Walter flew Messerschmitt Bf-109s for six months and Reimar worked for Operation Sea Lion, whose objective was the invasion of England. Upon the cancellation of this operation the Horten brothers went on to continue their projects, developing many enhanced versions of their original flying-wing. In 1942 Reimar began working on the Ho VII at the Luftwaffe's request, a machine equipped with two pusher-type propellers and a pulse jet engine. However, the Ho VII was not strong enough to fly safely at the greater speeds made possible by the jet, so the brothers began work on the new Ho IX (code named "Go 229"), the first functional jet propelled flying wing. The arrival of the American army in 1945 ended the construction of this type of aircraft. After the war, Reimar moved to Argentina where he continued to develop his unorthodox aircraft designs; Walter stayed in Germany. Walter died in 1988 and Reimar died in 1994.

[6:10] Reimar destroys some, but not all, the documents he carried about the Junkes 004 engine; [9:00] Reimar picked up by Americans in the Harz Mountains, by jeep to Göttingen, DC-3 aircraft to London, arrived 7 April 1945 [11:54]. Reimar on some problems with the 004 engine (as installed in Horten IX at Göttingen?). [14:14] Reimar heard "propaganda" about concentration camps, the situation in the concentration camps "was a thing of propaganda" [15:10] …Reimar visited Sachsenhausen, Nordhausen.

[25:20] Walter gets 30 SS men to help his team until the end of the war, "good hard workers." [26:27] Flight test program at Oranienburg on Horten IX V2, Reimar and Walter told Ziller to make 30-minute flights at 4,000 meters altitude or less, Ziller reported that the Horten IX could out-turn Me 262 in mock dogfights (so flown more than 3 times?!), landed more slowly, could out-climb that aircraft, Horten IX could climb about 20-22 meters per second, based on telephone reports from Ziller, these were Reimar's "impressions," precise measurements not made. [34:12] Fastest speed, not over 500 kph or over 4000 m = 600 kph, Ziller climbed at full throttle but did not use full throttle in level flight. [41:30] Ziller made 8-10 flights in Horten IX V2, says Reimar. Reimar on Rössler, he needed to be "protected," medical condition, other trauma? [46:39] Ziller landed "hard" in Horten IX V2, bent struts, lost 14 days repairing the aircraft in January 1945 …Reimar discusses these repairs, allocation of men, tools, etc. [55:06] Horten IX V2 a sensational airplane to other personnel at Oranienburg, Myhra says they called it "Fledermaus," or bat. [56:00] Walter ordered a Horten IV brought to Oranienburg to demonstrate high-performance sailplane to Göring's staff, RLM officials visited, to sell aero community on all-wing potential, Schiedhauer could fly in spare time. [59:00] Walter reported one of the turbines stalled …Reimar believed engine ok, Walter reported engine sometimes stalled during start, Junkers mechanics found nothing wrong.

Reimar then describes possible speed range of jet aircraft, 747, Horten IX, with original small center section 960 kph, with larger center section 920 kph, Reimar estimated these speeds and he did not want to claim 1,000 kph, as Walter urged. Ziller thought Horten IX capable of 900 kph [45:00]. Reimar on dynamic pressure vis-a-vie wing skin thickness, etc. [48:18] Horten IX wingtips required reinforcement of wood with metal strips, Dr. Pinton at Dynamit AG had a glue that would bond aluminum and wood, Reimar tested concept and practiced bonding procedure on Horten IV b, but Wilkenson dismissed IV b work as wasteful diversion [50:30] …also had to reinforce Horten IX V3 but hide metal strips from radar. [53:29] Reimar on glue developed by Dr. Pinton at Dynamit AG to bond plastics, also good for fuel-proof coating inside Horten IX wet-wing, etc… Reimar's ideas for increasing torsional stiffness in wingtip, aiming to withstand 5,000 kg/m² dynamic pressure.
