Unless you meant to link to an article about prison strikes, the link is bad.

I was expecting an article about the DC-10.

That is so freaking completely awesome. Seems to go a long way toward realizing Heinlein's vision of single-stage rocket ships.

Thanks for sharing.

Post Re: The DC-X Lives!
Way cool to watch, but two words occur to me: fuel costs.

The problem with this kind of design is that as much fuel, or more, is required for landing as for takeoff. I can't envision a working model that would have a meaningful payload and carry enough fuel for even a single takeoff and landing with safety reserves.

Until and unless we develop propulsion systems with much greater delta-vee per pound, unpowered descent and landing will be the only workable spaceflight option.

I know, I'm such a wet blanket.
