Guest: Open Lines. Topics: why human spaceflight, NASA, Fox News, making the case for space, different paths to space development. In the first segment of this Open Lines program, I talked about making the compelling case for human spaceflight. I mentioned a blog article on this subject on www.outofthecradle.net where blogger Ken said that the case was being made all the time. I talked about my responses and those of a few others commenting on Ken's article saying it was not so.
