Rather, they hired the same LGM for consultants. Or the same
nazis from Gothaer Waggonfabrik...


More likely Horten, given the overall design.

Gothaer Waggonfabrik made the jet-engined version (Go-229) of the Horten
IX. gliders. One of them is in the USA.

I assume that this is based on publicly released information, at least

local Walmart store for $5000.00 ;-)

It would be rather like 50USD and the NRA would like it. Gives a new
meaning to the 2nd amendment.
