Jerry Pournelle points us towards an article at Air & Space on the DC-X/DC-XA aka the "Delta Clipper"
I remember watching a video of the DC-X at ConFransico, where Jerry spoke the immortal lines:
That my friends is a SPACESHIP! And she lands like God and Robert A. Heinlein intended, on her jets!
I'm not really sure what he said next, since at that point there were several thousand people cheering at the top of their lungs.
Of course, that was before they transferred the program to NASA...
