@kchangnyt And those airplanes can't cross the ocean like dirigibles can! The argument never changes. :-)

@RocketAcademy If slamming NASA for not having a Mars roadmap, seems also silly to laud nonexistent DARPA paper plane as revolutionary.

@kchangnyt XS-1 contractors have been working for months; a Orion contractors for years. Millions of $ vs. billions. Silly comparison.

@RocketAcademy Right. XS-1 contractors have been sketching for months. Northrup has cute model. Ergo space transport revolution.

@kchangnyt Hardware doesn't materialize overnight. Do you think Orion was built in six months?

@kchangnyt The Bush Vision of Space Exploration was announced in 2004. Complaining that DARPA hasn't build a Spaceplane in 6 mo seems odd.

@RocketAcademy I'm not complaining about DARPA. I'm saying it's silly to extrapolate from incomplete paper study to revolution as done deal.

@kchangnyt Yet, you extrapolate from a suborbital launch of a Sesame Street toy and a rubber duck to NASA astronauts on Mars?
