If Dyna-Soar and the Space Launching System had been completed, the United States would have had by 1965 a modern modular launch vehicle launching a reusable manned spaceplane -- something it now hopes to accomplish with the Delta IV / OSP by 2010. The nation could have been spared the false premise of the shuttle program and had a space station ferry in being by the beginning of the 1970's. It might even have been flying well into the 21st Century, while the Gemini, Apollo, and Shuttle were consigned to the trash heaps of history.
