Given the recent feat of landing a rocket vertically by SpaceX ( https://www.youtube.com/watch?v=aL_NZYD3YbY ), I figured i'd post up a complete set of Convair Astronautics SCDs. Convair's rocket designs continue in use today.... for complete information, please see this link: https://en.wikipedia.org/wiki/Atlas-Centaur Thanks are due to several SCD collectors for allowing this set to be put together.
