For those unfamiliar with the Horten Ho-IX V1, it was the 1:1 unpowered aerodynamic testbed for the Ho-229 we are all familiar with. It was fitted with trapezoidal spats for the non-retractable Me-109 main landing gear and an open compartment above the rear of the wing for a drag chute. It was successfully flown numerous times, so it's not a "Napkinwaffe 1946" subject. Many years ago I attempted to convert a Pioneer Ho-229 into this configuration, but I was not sufficiently skilled to carry out my plan.
The Sanger "antipodal bomber" was a serious proposal for the world's first sub-orbital warplane. It had diamond cross section airfoils, the type of which was tested post-war, as well as finding their way onto missiles. The spaceplane was to have been launched using a rocket sled with a disposable booster. Supersonic wind tunnel tests were conducted using models, but no actual hardware was constructed. Based on the state of the art back then in materials and orbital mechanics, it was unlikely that anything would have materialized in time. And the landing gear are located waaaaaay too forward to allow a practical landing. Nevertheless, it is an interesting proposal that presaged post-war projects like the X-20 Dyna-Soar.
And if anyone hasn't figured it out, yes I am thrilled by the news of the incoming kits!
