I think the key question for space and aviation enthusiasts is whether or not the Pentagon is building a hypersonic suborbital manned bomber. If they are -- and it's a big "if" -- then that means the technology for civilian use is just a couple/few decades away. I haven't seen the numbers, but in my mind the market for suborbital commercial flights, say, New York to Sydney in an hour or two, is already there. It's a place on the road to reducing cost-to-orbit where the money's already there. Somebody just has to go get it. Plus DoD will end up solving most of the problems by being the first mover.
