Mossie and kitnut617,
Thanks for responding. The Tie Fighter pressure suit might be too "modern" looking (if "THE FUTURE" is indeed modern!) and close-fitting, but I appreciate the offer. I'm searching for a clunky, bulky look.
The astronauts are more "bulky" and more what I had in mind for the body, but it looks like the helmet and/or faceplate would be "solid" plastic. For "real" space use (that is, EXPERIENCED space folk, not my "stone-age", first-timer high altitude guy) they coat the faceplate with thin reflective stuff that, from a distance, looks solid. I could get away with paint on the faceplates of the astronauts for use with modern spacecraft, but I wanted a clear spherical bubble if at all possible for "my guy". Both Astronauts and deep-sea divers only "need" to see forward, but my pilot would need more peripheral vision.
