Guest: William Grahame was the guest for this Space Show program to discuss hypersonic R&D, programs, and flight. We began the discussion with a short summary of some of the existing or better known hypersonic and scramjet programs including Hi-Fire, Blackswift, and Falcon. We talked about development of these vehicles needing to come from the military side of things, not civil or the private sector. We also talked about educating the public as to why hypersonic vehicles are important and how the press is probably not that aware of their importance.

Guest: David Hoerr, co-author of "The Rocket Company," was the guest for this Space Show program. We started our discussion on the topic of Point A to Point B suborbital transportation as David had written a thoughtful piece on the subject in The Space Review on May 5, 2008. Please see: www.thespacereview.com/article/1118/1. David received lots of listener questions about the military version of Point A to Point B suborbital transportation, commercial versions, the market for such versions, and the advances needed in technology.
