Yeah, I was thinking the same thing. Sounds like more like how NASA is than defense projects. I like the spirit though.

The Engineering On Friday: "Up, Up, and Away" is all about this rocket/plane. It is a shame they lost it.
There were several good technology predictions in SciFi conference calle "High Frontier". You should look it up, it outlines a number of potential weapons based upon this and other technologies.
