  Because I KNOW it won't be done by anyone alive today. Which leaves it wide open.

  • • Your preference for air-breathing rockets does not invalidat — Ex-News Junkie, Tue Dec 5 6:48pm
      e the idea of a space elevator. Rockets carrying an handful of astronauts will play a small role in the future I envision, but generally they will be obsolete.

        Space Elevator cannot possibly be made to work. DFM

        • • Ramjets would not use ozone depleting chemicals such as — DFM, Mon Feb 12 10:08am

            Rocket technology is not guarded merely due to its potential for weaponization. Rockets were originally intended, built and used, as weapons. Peaceful uses came later, much later. Large rockets, for... more
