Dave Ketchledge was the special guest for this Space Show program. Mr. Ketchledge has written a comprehensive and valuable book, "The Next Shuttle" and we discussed this work in detail. Mr. Ketchledge went into the specifics about lifting bodies, why they are not being used when the technology is available, he spoke about the Andrews Space Technology Alchemist Gryphon TSTO theoretical RLV and the Northrop Grumman variation of Alchemist. In discussing his book, we talked about many relevant issues so I strongly suggest those of you interested in affordable space access, RLV technology, our history to date and who is doing what and how, listen to this program. You can also order book online in CD format by by visiting Dave's website, www.rocketengineer.bravehost.com or by visiting www.arapress.com/tns.html. Dave can be contacted at sketchledge@sbcglobal.net. In addition to discussing his book and RLV technology, we discussed his software Flight Dynamics 4. This is a refined engineering and design tool that handles changes in thrust, altitude, supersonic flight and subsonic compressibility and you can store everything and work it from your PC. We extended this program by half an hour to discuss terrestrial based nuclear power technology given our ongoing energy issues with fossil fuels and the fear around nuclear power. Dave, having worked in nuclear power industry and with our nuclear submarine fleet for 40 years, brought us up to date on the reality of reactor safety, proliferation, waste, waste storage, coal plants and their radiation, and radiation in general. You will not want to miss this part of our discussion. Again, you can contact Dave Ketchledge at sketchledge@sbcglobal.net if you have additional comments or questions for him.
