In turn, Thank you sir!
Pm sent, with much interest and gratitude.
Aerospace planes (as opposed to rockets) are one of the "themes" I'm interested in.
I'm still searching for the Russian (E50/50) "Spiral" as well, which actually flew, and which may have been modelled. If searching produces no result, I'll eventually design one for myself, and share it in turn.
Kind and Respectful Regards Dyna-Soar, Uyraell
