Wrong, see the F-117, B-2, the space shuttle itself (in particular it's ceramic tiles), the X-33 and the 787. All of them use composite polymer or ceramic structures, things that were mostly impossible to build fifty years ago.

Of course it was, which is why NASA originally went for the X-33 then the SLS. It's also why Boeing is doing the XS-1 instead of a shuttle 2.0 (which they own because they bought Rockwell).
