Working conditions in Argentina, quality of labor, and other difficulties designing, building, and flying airplanes in that country; [4:52] towed Pulqui II with Ju 52. [9:42] Reimar's work on H IX center section, Reimar discusses the 17mm-thick plywood used to cover the center section, different layers of wood, glue, experimenting with Horten II to work out design of turbine air intakes without turbulence, angle of intake relative to wing chord … [16:00] Schiedhauer flew the test Horten II (Horten IX nose intakes), [17:03] BMW 003 engines considered for Horten IX but not ready; [18:10] Franz told Reimar he could turn 004 ninety degrees to accommodate 004 in center section, as originally designed, but RLM said no. [21:00] Reimar describes problems with resizing the center section to accept 004 with accessories, [25:48] center section geometry (of steel tubes) changed four times – changes in air intake placement and geometry, 003 to 004, then when Junkers arrived with accessories on the exterior of the engine, (4th change?) … 003 size changed and clearance between engine and structure, temperature and maintenance concerns. [28:24] Turbine mockup different from actual engine (BMW 003). After all changes, Center of Gravity balanced without need for ballast [29:21].

[35:30] Reimar sent his own men to visit Franz for guidance to use 004 …more details on rotating 004 to fit center section, Reimar and Myhra refer to photos of the Horten IX V3 center section, "rotated about 15 degrees" on the drawing …extended discussion about placement of engines with reference to drawings or photographs of Horten IX V2 and V3 …Myhra and Reimar agree that the top wing surface on the Horten IX V2 (Reimar's exclusive design) was much smoother than Horten IX V3 altered by Gotha, Reimar cannot explain why the changes. More discussion about shape of center section on V3, engine placement, surface details. [59:03] "The drawing is bad." – Reimar detects error in the drawing they are studying.
