Oh, man, now you went and did it -- got me all bristling with curiosity, as my knowledge of the Horton Bros. and the flying wing (I LOVE flying wings, and have even had dreams of flying in them), is cursory. Will you elaborate on your comment above? It sounds interesting! And when I think about all the great German scientists who came to America after WWII (one of my faves, Werner von Braun, for example), it makes me think ... what about the ones who stayed behind, in East Germany? What diabolical feats of aeronautical engineering did they accomplish that we never saw -- or, perhaps, never recognized when we saw them???
Anyway, please elaborate!! I'm fascinated!
A recent book, “Area 51, An Uncensored History” by Annie Jacobson touches on this subject. It is a good read and available on Kindle. It is especially interesting regarding the Rosewell Incident.
